Forums Application Using MVC4 and Entity Framework

Hi all in this article I would like to show you how to create a forums application using MVC4 and Entity Framework.

This application mainly covers the following:

1. Registering a User.
2. Login.
3. Create questions on the technology available.
4. Add reply's to the posted questions.

There were also several things included like getting the last reply posted for the question and also not allowing the user to post questions or replies without logging in.

The database for the current application has the necessary tables and Stored Procedures as follows:

Ok now let's create an MVC application.

 

 

 

 

Open your "_ViewStart.cshtml" that is present in the "VIEWS->Shared" folder and replace the contents with the following:
 

 

<!DOCTYPE html>

<html>

<head>

    <meta charset="utf-8" />

    <meta name="viewport" content="width=device-width" />

    <title>@ViewBag.Title</title>

    @Styles.Render("~/Content/css")

    @Scripts.Render("~/bundles/modernizr")

    <script src="@Url.Content("~/Scripts/tinymce/jquery.tinymce.js")" type="text/javascript"></script>

</head>

<body>

    <div id="branding">

    </div>

    <div>

        @if (Session["UserName"] != null)

        {

            <div class="logged_in" id="user_navigation" runat="server">

                <a title="Your Profile" href="">@*<img height="50" width="50" class="photo" src='<%= Url.Action( "GetPhoto", "image", new { photoId = Session["UserName"] } ) %>' />*@

                    <img alt="" src="@Url.Action("GetPhoto", "User")" height="50" width="50" class="photo" />

                </a>

                <div id="user_info">

                    <p>

                        <span class="hide">Signed in as </span><a href="" title="Your Profile" class="ipbmenu">

                            <span class="ipbmenu">@Html.Label("Name", Session["UserName"].ToString()) </span>

                        </a>

                        <img alt="&gt;" src="http://www.gimptalk.com/public/style_images/master/opts_arrow.png" />

                    </p>

                    <ul class="boxShadow" id="user_link_menucontent" style="display: none; position: absolute;

                        z-index: 9999;">

                    </ul>

                    <ul id="user_other">

                        <li><a href="../User/Logout">Logout</a> </li>

                    </ul>

                </div>

                <br />

            </div>

@*<strong>@Html.Encode(User.Identity.Name)</strong>

            @Html.ActionLink("Log Out", "Logout", "User");*@

        }

        else

        {

            <div class="not_logged_in" id="user_navigation" runat="server">

                <a class="rounded" id="A1" title="Sign In »" href="../User/Login"><span class="left">

                    Sign In »</span> <span class="services right"></span>

                    <br />

                </a>

                <br />

                <span class="links">New user? <a id="register_link" title="Register Now!" href="../User/Register">

                    Register Now!</a>&nbsp; </span>

            </div>

        }

    </div>

    <div id="primary_nav">

        <ul>

            <li class="left active" id="nav_discussion" runat="server"><a title="Go to Forums"

                href="@Url.Action("Main", "Home")">Forums</a></li><li class="left" id="nav_members"

                    runat="server"><a

                    title="Go to Member List" href="@Url.Action("Members", "Home")">Members</a></li>

        </ul>

    </div>

    @RenderBody()

    @Scripts.Render("~/bundles/jquery")

    @RenderSection("scripts", required: false)

</body>

</html>

 

If you would like to include your own scripts and CSS then open the "BundleConfig.cs" that is present in the "App_Start" folder and you will see CSS or scripts included that you need to add the following to:

 

bundles.Add(new StyleBundle("~/Content/css").Include("~/Content/css/ipb_common.css",                "~/Content/css/ipb_editor.css",                 "~/Content/css/ipb_help.css",                 "~/Content/css/ipb_login_register.css",                 "~/Content/css/ipb_print.css",                 "~/Content/css/ipb_styles.css", "~/Content/css/ipb_ucp.css"));

Now let us create a Model with two classes, namely "userModel" and "Register".

 

 

 

 

Copy and paste the following code in your class and build the application.

 

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel.DataAnnotations; using System.ComponentModel.DataAnnotations.Schema; using System.Web.Mvc;   namespace mvcForumapp.Models {     public class userModel     {         [Required]         [DataType(DataType.EmailAddress)]         [Display(Name = "Email address")]         [MaxLength(50)]         [RegularExpression(@"[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4}", ErrorMessage = "Please enter correct email")]         public string Email { get; set; }           [Required]         [DataType(DataType.Password)]         [Display(Name = "Password")]         public string password { get; set; }     }       public class Register     {         [Required(ErrorMessage = "username required")]         [Display(Name = "Choose username")]         [StringLength(20, MinimumLength = 4)]         [Remote("IsUserNameAvailable", "Register", "Username is already taken")]         public string Username { get; set; }           [Required(ErrorMessage = "display required")]         [StringLength(20, MinimumLength = 4)]         [Remote("IsDisplayAvailable", "Register", "displayname already taken")]         public string Displayname { get; set; }           [Required(ErrorMessage = "EmailAddress required")]         [DataType(DataType.EmailAddress)]         [Display(Name = "Email address")]         [MaxLength(50)]         [RegularExpression(@"[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4}", ErrorMessage = "Please enter correct email")]         [Remote("IsEmailAvailable", "Register", "EmailAddress is already taken")]         public string Email { get; set; }           [Required(ErrorMessage = "password required")]         [DataType(DataType.Password)]         [StringLength(20, MinimumLength = 8)]         [Display(Name = "Password")]         public string password { get; set; }           [Required(ErrorMessage = "password required")]         [DataType(DataType.Password)]         [Compare("password", ErrorMessage = "password didn't match")]         [StringLength(20, MinimumLength = 8)]         public string PasswordConfirm { get; set; }     } }

Now let us create a controller and provide the name you need, or since we are initially trying to create and register a user, the name "UserController" is a better naming convention that will make your work easy in MVC otherwise we will encounter problems when we implement or work on large applications.

 

 

Name it "Register".

 

 

 

First let us work on user registeration. As I said, we are using Entity Framework to add an entity model to our project, from the tables and Stored Procedures that I provided, you can easily add an Entity Model to the application, Entity Framework 

beginners can check my previous articles explaining how to add a model to the project from here:

 

http://www.c-sharpcorner.com/UploadFile/Dorababu742/entity-framework-crud-operations-using-stored-procedure/

 

Now replace your controller code with the following

 

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.UI;   namespace mvcForumapp.Controllers {     public class UserController : Controller     {         //         // GET: /User/           newForumDBEntities db = new newForumDBEntities();           public ActionResult Index()         {             return View();         }           [HttpGet]         public ActionResult Register()         {             return View();         }           public ActionResult IsUserNameAvailable(string UserName)         {             var usrAvailable = db.tblUsers.Where(p => p.UserName == UserName).Select(img => img.UserName).FirstOrDefault();               if (usrAvailable == null)             {                 return Json(true, JsonRequestBehavior.AllowGet);             }             //string html = "<span style='color:Red;'> Username in use</span>";             return Json("<span style='color:Red;'> Username in already in use</span>", JsonRequestBehavior.AllowGet);           }           [OutputCache(Location = OutputCacheLocation.None, NoStore = true)]         public JsonResult IsDisplayAvailable(string Displayname)         {             var usrAvailable = db.tblUsers.Where(p => p.DisplayName == Displayname).Select(img => img.DisplayName).FirstOrDefault();               if (usrAvailable == null)             {                 return Json(true, JsonRequestBehavior.AllowGet);             }             //string html = "<span style='color:Red;'> Username in use</span>";             return Json("<span style='color:Red;'> Display name in already use</span>", JsonRequestBehavior.AllowGet);           }           [OutputCache(Location = OutputCacheLocation.None, NoStore = true)]         public JsonResult IsEmailAvailable(string Email)         {             var usrAvailable = db.tblUsers.Where(p => p.EmailID == Email).Select(img => img.EmailID).FirstOrDefault();               if (usrAvailable == null)             {                 return Json(true, JsonRequestBehavior.AllowGet);             }             //string html = "<span style='color:Red;'> Username in use</span>";             return Json("<span style='color:Red;'> Emai in already in use</span>", JsonRequestBehavior.AllowGet);           }           [HttpPost]         public ActionResult Register(mvcForumapp.Models.Register user, HttpPostedFileBase file)         {             if (ModelState.IsValid)             {                 if (file == null)                 {                     ModelState.AddModelError("File", "Please Upload Your file");                 }                 else if (file.ContentLength > 0)                 {                     int MaxContentLength = 1024 * 1024 * 3; //3 MB                     string[] AllowedFileExtensions = new string[] { ".jpg", ".gif", ".png", ".pdf" };                       if (!AllowedFileExtensions.Contains(file.FileName.Substring(file.FileName.LastIndexOf('.'))))                     {                         ModelState.AddModelError("File", "Please file of type: " + string.Join(", ", AllowedFileExtensions));                     }                       else if (file.ContentLength > MaxContentLength)                     {                         ModelState.AddModelError("File", "Your file is too large, maximum allowed size is: " + MaxContentLength + " MB");                     }                     else                     {                         using (var db = new newForumDBEntities())                         {                             Byte[] imgByte = null;                             HttpPostedFileBase File = file;                             //Create byte Array with file len                             imgByte = new Byte[File.ContentLength];                             //force the control to load data in array                             File.InputStream.Read(imgByte, 0, File.ContentLength);                             var userdets = db.tblUsers.CreateObject();                             userdets.UserName = user.Username;                             userdets.DateJoined = DateTime.Now;                             userdets.DisplayName = user.Displayname;                             userdets.EmailID = user.Email;                             userdets.Password = user.password;                             userdets.Photo = imgByte;                             //var encrppass = Encrypt(user.password, true);                             //var userdets = db.tblUsers.CreateObject();                             //userdets.EmailID = user.Email;                             //userdets.password = encrppass;                               db.tblUsers.AddObject(userdets);                             db.SaveChanges();                             return RedirectToAction("Main", "Home");                         }                     }                 }               }             return View(user);         }     } }

 

Now let us create a View for registering inside the controller. There are two action results with the same name "Register" but the functionality is different, one is for HttpGet that just returns a view with controls and the other is for HttpPost to post the data to the database.

 

 

 

 

 

You can also create a strongly-type view by selecting the desired class from the drop-down and select create in the Scaffold template if you would like to have your own design just create an empty view.

 

Your view initially, if you didn't select a strongly-typed view, will be as follows:

 

@{

    ViewBag.Title = "Register";

    Layout = "~/Views/Shared/_Layout.cshtml";

}

Changes in "RouteConfig.cs" that is in the "App_Start" folder:
 

 

public static void RegisterRoutes(RouteCollection routes)         {             routes.IgnoreRoute("{resource}.axd/{*pathInfo}");             routes.MapRoute(                 name: "Default",                 url: "{controller}/{action}/{id}",                 defaults: new { controller = "User", action = "Index", id = UrlParameter.Optional }             );         }

 

 

Now run the application and you will be shown the following:

 

 

 

Clicking on "Register" will route to the Register view and "Login" will route to the Login view.

 

This is how the register view looks:

 

 

 

 

 

Remote validation:

 

Check here for the implementation of remote validation http://msdn.microsoft.com/en-us/library/gg508808(v=vs.98).aspx

 

Here I checked whether Username, displayname and email exist, if the do not exist then remote validation fires if not then it will not show an error.

 

 

If everything is fine then you are ready to register.

 

 

 

After you are registered, it will route back to the default page.

 

Now let us work on Login as you already create a Model let us work on creating a controller for Login and required Views.

 

Follow as we do for Register starting from the controller, first add a controller named "logincontroller" in the "Controller" folder then replace it with the following code:

 

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc;   namespace mvcForumapp.Controllers {     public class LoginController : Controller     {         newForumDBEntities db = new newForumDBEntities();           [HttpGet]         public ActionResult Login()         {             return View();         }           [HttpPost]         public ActionResult Login(mvcForumapp.Models.userModel user)         {             if (ModelState.IsValid)             {                 if (isValid(user.Email, user.password))                 {                     var user1 = db.tblUsers.FirstOrDefault(u => u.EmailID == user.Email).UserName;                     Session["UserName"] = user1;                     //FormsAuthentication.SetAuthCookie(user.Email, false);                     return RedirectToAction("Index", "Register");                 }                 else                 {                     ModelState.AddModelError("", "Login Data is Incorrect");                 }             }             return View(user);         }           private bool isValid(string Email, string password)         {             //string crypto = Encrypt(password, true);             bool isvalid = false;             using (var db = new newForumDBEntities())             {                 var user = db.tblUsers.FirstOrDefault(u => u.EmailID == Email);                 if (user != null)                 {                     if (user.Password == password)                     {                         isvalid = true;                     }                 }               }             return isvalid;         }     } }

 

Add Views correspondingly as we did for "Register", after adding the view your login view your run will look as follows:

 

 

 

After successful login you will be shown your user name along with your image as follows, before that ensure you implement code for showing the image of the user logging in; we will implement that as follows.

 

You will see your "_Layout.cshtml" as follows:

 

<img alt="" src="@Url.Action("GetPhoto", "User")" height="50" width="50" class="photo" />

 

This means we are trying to load the image from the "controller(User)" with the method or function name "GetPhoto"; change it as per your controller and method here. For a better understanding I will create a new controller and name it "displayImage" with the function "ShowImage" so my image source will be as follows:

now <img alt="" src="@Url.Action("ShowImage", "displayImage")" height="50" width="50" class="photo" />

 

Your controller code to display the login user image is as follows:

 

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc;   namespace mvcForumapp.Controllers {     public class displayImageController : Controller     {         //         // GET: /displayImage/         newForumDBEntities db = new newForumDBEntities();           public ActionResult Index()         {             return View();         }           [HttpGet]         public ActionResult ShowImage()         {             string user = Session["UserName"] as string;             byte[] photo = null;             var v = db.tblUsers.Where(p => p.UserName == user).Select(img => img.Photo).FirstOrDefault();             photo = v;             return File(photo, "image/jpeg");         }     } }

 

Here is what you will see after successful login:

 

 

 

Now let us create a controller and a view for logout. Create a controller and name it "Logout" and then replace your controller with the following:

 

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc;   namespace mvcForumapp.Controllers {     public class LogoutController : Controller     {         //         // GET: /Logout/           public ActionResult Logout()         {             Session.Abandon();             return RedirectToAction("Index", "Register");         }       } }

 

Now add a view by right-clicking on the "Logout" action result and select the master page. Your view should be as follows:

 

@{

    ViewBag.Title = "Logout";

    Layout = "~/Views/Shared/_Layout.cshtml";

}

<h2>Logout</h2>

After successful log-out you will be routed to the main view again.
 

So far so good. Now let us create Controllers and Views for the rest, i.e posting questions, replies and all. First let us bring all the Questions from the database from each technology.    

As we are using Entity Framework each and every Stored Procedure from the database is treated as a model, not only Stored Procedures but also tables.
 

First let us create a controller for displaying the list of technologies available and the number of topics and replies under each technology, also the last posted question information.
 

Create a controller and name it "Technology" and replace the code with the following code:

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc;   namespace mvcForumapp.Controllers {     public class TechnologyController : Controller     {         //         // GET: /Technology/         newForumDBEntities db = new newForumDBEntities();           public ActionResult Index()         {             List<mvcForumapp.selectStats_Result_Result> userview = db.selectStats_Result().ToList();             return View(userview);         }       } }

 

Create an empty View by right-clicking on "Index" and replace the view with the following:

 

@model IEnumerable<mvcForumapp.selectStats_Result_Result> @{     ViewBag.Title = "Main";     Layout = "~/Views/Shared/_Layout.cshtml"; } <div id="secondary_nav">     <ul class="left" id="breadcrumb">         <li class="first"><a href="">MVC-Forum Community</a></li>     </ul> </div> <div class="clear" id="content">     <a id="j_content"></a>     <h2 class="hide">         Board Index</h2>     <div class="clearfix" id="board_index">         <div class="no_sidebar clearfix" id="categories">             <!-- CATS AND FORUMS -->             <div class="category_block block_wrap">                 <h3 class="maintitle" id="category_47">                     <a title="View category" href="../Home/Main">Technology related questions</a></h3>                 <div class="table_wrap">                     <table summary="Forums within the category 'GimpTalk'" class="ipb_table">                         <tbody>                             <tr class="header">                                 <th class="col_c_icon" scope="col">                                     &nbsp;

Earlier I set the default routing view as Index from Register, so let us change that so when someone hits, the default view will be shown with the list of questions.

Changes in "RouteConfig.cs" that is in the "App_Start" folder:
 

 

public static void RegisterRoutes(RouteCollection routes)         {             routes.IgnoreRoute("{resource}.axd/{*pathInfo}");             routes.MapRoute(                 name: "Default",                 url: "{controller}/{action}/{id}",                 defaults: new { controller = "Technology", action = "Index", id = UrlParameter.Optional }             );         }

 

This is how your view looks when you run the application:

 

 

 

Ok since I have questions in each and every Technology, this was displayed. Add a new technology in the tblTechnology table and run your application, when there are no question in that technology you will have a chance to post new questions in that technology.

 

 

 

Currently we haven't implemented anything for that; it will show an error page instead. We will see how to post new questions later on. First let me show you how to display all questions available in the selected Technology. 

 

For the existing "Technology" controller I will add a few methods or you can add a new controller if you need to. I am adding the "a" method to the existing controller i.e "Technology" as follows:

 

 

 

public ActionResult DisplayQuestions()           {             int TechID = Convert.ToInt16(Request.QueryString["TechID"].ToString());               List<mvcForumapp.QuestionList_Result> disp = db.QuestionList(TechID).ToList();             return View(disp);         }

 

Create a view by right-clicking on "DisplayQuestions" and replace it with the following code:

 

@model IEnumerable<mvcForumapp.QuestionList_Result> @{     ViewBag.Title = "Details"; } <style type="text/css">     .disabled     {         /* Text and background colour, medium red on light yellow */         float: right;         margin-right: 20px;         background: #999;         background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#dadada), to(#f3f3f3));         border-top: 1px solid #c5c5c5;         border-right: 1px solid #cecece;

What will happen is, by selecting a particular technology in the image above will display all the questions related to that technology.

 

 

 

In this you can start a new Topic or post a new question if the user was logged in. 

 

So far so good. Let us create the final step in this i.e creating questions and posting replies, first let us see how to create questions.

 

Create a class in the model with the name "Questions"; your class should be as follows:

 

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel.DataAnnotations;   namespace mvcForumapp.Models {     public class Questions     {         [Required(ErrorMessage = "Title required")]         [Display(Name = "Enter Title")]         [StringLength(20, MinimumLength = 4)]         public string TopicTitle { get; set; }         [Required(ErrorMessage = "Description required")]         [Display(Name = "Enter Description")]         [StringLength(20, MinimumLength = 10)]         public string TopicDescription { get; set; }         [Required(ErrorMessage = "Content required")]         [StringLength(Int32.MaxValue, MinimumLength = 10)]         public string TopicContent { get; set; }     }

 

Create a controller with the name "Question" and replace the code with this:

 

public class QuestionController : Controller     {         [HttpGet]         public ActionResult PostQuestion()         {             int techID = Convert.ToInt16(Request.QueryString["TechID"].ToString());             return View();         }       }

 

This is how it is viewed when you route to the "PostQuestion" view:

 

 

 

Create another method in the same controller with HttpPost to post the question:

 

[HttpPost]         public ActionResult PostQuestion(mvcForumapp.Models.Questions user)         {             int techID = 0;             if (ModelState.IsValid)             {                 techID = Convert.ToInt16(Request.QueryString["TechID"].ToString());                 using (var db = new newForumDBEntities())                 {                     var userdets = db.tblQuestions.CreateObject();                     userdets.TechID = Convert.ToInt16(Request.QueryString["TechID"].ToString());                     userdets.QuestionTitle = user.TopicTitle;                     userdets.QuestionDesc = user.TopicContent;                     userdets.DatePosted = DateTime.Now;                     userdets.UserName = Session["UserName"].ToString();                     userdets.viewCount = 0;                     userdets.ReplyCount = 0;                     db.tblQuestions.AddObject(userdets);                     db.SaveChanges();                     return RedirectToAction("DisplayQuestions", "Technology", new { TechID = techID });                 }             }             return View(user);         }

 

 

After a successful post you will be routed to the list of questions for that technology.

 

You can do the same for replys by creating a class in "Model" with a name called "Replys" and adding the necessary for that. This is how it is displayed when a post has replys.

 

For viewing the questions with replies add "View" and "Controller" correspondingly and your code should be as follows in the controller:

 

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Data.SqlClient; using System.Data; namespace mvcForumapp.Controllers {     public class Question_AnswerController : Controller     {         newForumDBEntities db = new newForumDBEntities();         int vwcnt = 0;         [HttpGet]         public ActionResult displayQuestionwithAnswers()         {             var paramQuesID = new SqlParameter("@QuestionID", SqlDbType.Int);             var paramRepCnt = new SqlParameter("@viewcount", SqlDbType.Int);             int quesID = Convert.ToInt16(Request.QueryString["QuestionID"].ToString());             paramQuesID.Value = quesID;             var viewcount = db.tblQuestions.Where(e1 => e1.QuestionID == quesID).FirstOrDefault();             vwcnt = viewcount.viewCount;             if (vwcnt == 0)             {                 vwcnt++;                 paramRepCnt.Value = vwcnt;                 var v = db.ExecuteStoreCommand("UPDATE tblQuestions SET viewCount = @viewcount WHERE QuestionID = @QuestionID", paramRepCnt, paramQuesID);             }             else             {                 vwcnt = vwcnt + 1;                 paramRepCnt.Value = vwcnt;                 var v = db.ExecuteStoreCommand("UPDATE tblQuestions SET viewCount = @viewcount WHERE QuestionID = @QuestionID", paramRepCnt, paramQuesID);             }             List<mvcForumapp.Questionwithreplys_Result> disp = db.Questionwithreplys(quesID).ToList();             return View(disp);         }         [HttpGet]         public ActionResult GetPhoto()         {             //RouteData.Values["QuesID"]             int quesID = Convert.ToInt16(Request.QueryString["QuestionID"]);             byte[] photo = null;             var usrname = (from a in db.tblQuestions                            where a.QuestionID == quesID                            select new { a.UserName });             var v = db.tblUsers.Where(p => p.UserName == usrname.FirstOrDefault().UserName).Select(img => img.Photo).FirstOrDefault();             photo = v;             return File(photo, "image/jpeg");         }         [HttpGet]         public ActionResult ReplyPhoto()         {             //RouteData.Values["QuesID"]             int quesID = Convert.ToInt16(Request.QueryString["QuestionID"]);             byte[] photo = null;             var usrname = (from a in db.tblReplies                            where a.ReplyID == quesID                            select new { a.UserName });             var v = db.tblUsers.Where(p => p.UserName == usrname.FirstOrDefault().UserName).Select(img => img.Photo).FirstOrDefault();             photo = v;             return File(photo, "image/jpeg");         }     } }

 

View for the corresponding controller:

 

@model IEnumerable<mvcForumapp.Questionwithreplys_Result>   @{     ViewBag.Title = "Index";     Layout = "~/Views/Shared/_Layout.cshtml"; } <style type="text/css">     .disabled     {         /* Text and background colour, medium red on light yellow */         float: right;
