Step 1. Creating an MVC Application

Open Visual Studio
File à New Project…
Select ASP.NET MVC3/4 Web Application.
Enter the name of Application as "CodeFirstDemo".
Click OK.

Step 2. Creating the Model

Right click on the Models folder and create a model with the name of "ProjectModels" and create properties, as shown in the code, given below:

ProjectModels.cs

namespace MvcXML.Models
{
public class ProjectModels {
public int Id {
get;
set;
}
[Required]
public string ProjectName {
get;
set;
}
[Required]
public string Location {
get;
set;
}
public bool IsEdit {
get;
set;
}
}
}

Step 3. Create a XML File

Create a folder with the name of XML, as shown in the following picture, and create an XML file with the name of "ProjectList.XML", using Add a New Item by right clicking on XML folder. Write the code as follows in XML file.

ProjectList.xml

<?xml version="1.0" encoding="utf-8"?>
<Projects>
<Project>
<Id>1</Id>
<ProjectName>The Primus</ProjectName>
<Location>Gurgaon</Location>
</Project>
<Project>
<Id>2</Id>
<ProjectName>DLF</ProjectName>
<Location>Gudgoan</Location>
</Project>
<Project>
<Id>4</Id>
<ProjectName>Dev Builders</ProjectName>
<Location>Grater Noida</Location>
</Project>
</Projects>

Step 4 : Create a Controller.

Right click on the Controller folder and create a controller with the name of "AdminController", as shown in the picture below. Write the code given below in Admincontroller within an Index Action.

AdminController.cs

public class AdminController: Controller {
//
// GET: /Admin/
public ActionResult Index() {
List < ProjectModels > lstProject = new List < ProjectModels > ();
DataSet ds = new DataSet();
ds.ReadXml(Server.MapPath("~/XML/ProjectList.xml"));
DataView dvPrograms;
dvPrograms = ds.Tables[0].DefaultView;
dvPrograms.Sort = "Id";
foreach(DataRowView dr in dvPrograms) {
ProjectModels model = new ProjectModels();
model.Id = Convert.ToInt32(dr[0]);
model.ProjectName = Convert.ToString(dr[1]);
model.Location = Convert.ToString(dr[2]);
lstProject.Add(model);
}
if (lstProject.Count > 0) {
return View(lstProject);
}
return View();
return View();
}
ProjectModels model = new ProjectModels();
public ActionResult AddEditProject(int ? id) {
int Id = Convert.ToInt32(id);
if (Id > 0) {
GetDetailsById(Id);
model.IsEdit = true;
return View(model);
} else {
model.IsEdit = false;
return View(model);
}
}
[HttpPost]
public ActionResult AddEditProject(ProjectModels mdl) {
if (mdl.Id > 0) {
XDocument xmlDoc = XDocument.Load(Server.MapPath("~/XML/ProjectList.xml"));
var items = (from item in xmlDoc.Descendants("Project") select item).ToList();
XElement selected = items.Where(p => p.Element("Id").Value == mdl.Id.ToString()).FirstOrDefault();
selected.Remove();
xmlDoc.Save(Server.MapPath("~/XML/ProjectList.xml"));
xmlDoc.Element("Projects").Add(new XElement("Project", new XElement("Id", mdl.Id), new XElement("ProjectName", mdl.ProjectName), new XElement("Location", mdl.Location)));
xmlDoc.Save(Server.MapPath("~/XML/ProjectList.xml"));
return RedirectToAction("Index", "Admin");
} else {
XmlDocument oXmlDocument = new XmlDocument();
oXmlDocument.Load(Server.MapPath("~/XML/ProjectList.xml"));
XmlNodeList nodelist = oXmlDocument.GetElementsByTagName("Project");
var x = oXmlDocument.GetElementsByTagName("Id");
int Max = 0;
foreach(XmlElement item in x) {
int EId = Convert.ToInt32(item.InnerText.ToString());
if (EId > Max) {
Max = EId;
}
}
Max = Max + 1;
XDocument xmlDoc = XDocument.Load(Server.MapPath("~/XML/ProjectList.xml"));
xmlDoc.Element("Projects").Add(new XElement("Project", new XElement("Id", Max), new XElement("ProjectName", mdl.ProjectName), new XElement("Location", mdl.Location)));
xmlDoc.Save(Server.MapPath("~/XML/ProjectList.xml"));
return RedirectToAction("Index", "Admin");
}
}
public ActionResult Delete(int Id) {
if (Id > 0) {
XDocument xmlDoc = XDocument.Load(Server.MapPath("~/XML/ProjectList.xml"));
var items = (from item in xmlDoc.Descendants("Project") select item).ToList();
XElement selected = items.Where(p => p.Element("Id").Value == Id.ToString()).FirstOrDefault();
selected.Remove();
xmlDoc.Save(Server.MapPath("~/XML/ProjectList.xml"));
}
return RedirectToAction("Index", "Admin");
}
public void GetDetailsById(int Id) {
XDocument oXmlDocument = XDocument.Load(Server.MapPath("~/XML/ProjectList.xml"));
var items = (from item in oXmlDocument.Descendants("Project") where Convert.ToInt32(item.Element("Id").Value) == Id select new projectItems {
Id = Convert.ToInt32(item.Element("Id").Value),
ProjectName = item.Element("ProjectName").Value,
Location = item.Element("Location").Value,
}).SingleOrDefault();
if (items != null) {
model.Id = items.Id;
model.ProjectName = items.ProjectName;
model.Location = items.Location;
}
}
public class projectItems {
public int Id {
get;
set;
}
public string ProjectName {
get;
set;
}
public string Location {
get;
set;
}
public projectItems() {}
}
}

Now, create a View for the action, using right click on the controller's action and write the code as follows for the Index and AddEditProject respectively.

Index.cshtml file.

@model IEnumerable
<MvcXML.Models.ProjectModels>
@{
ViewBag.Title = "Index";
}
<style type="text/css">
.topDiv
{
width: 50%;
margin: 10px auto;
background-color: #f2f2f2;
text-align: left;
padding: 2%;
}
</style>
<div class="topDiv">
<fieldset style="margin: 2% auto; width: 90%; background-color: #FFEBCD; text-align: center">
<h4>
@Html.ActionLink("Add New project", "AddEditProject")
</h4>
</fieldset>
<fieldset>
<table style="margin: 2% auto; padding: 5px; width: 90%">
<tr style="background-color: #FFFACD">
<th>
ProjectName
</th>
<th>
Location
</th>
<th>
Manage
</th>
</tr>
@{
foreach (var item in Model)
{
<tr style="background-color: #FFFFF0">
<td>
@item.ProjectName
</td>
<td>
@item.Location
</td>
<td>
@Html.ActionLink("Edit", "AddEditProject", new { id = @item.Id }) / @Html.ActionLink("Delete", "Delete", new { id = @item.Id })
@* /@Html.ActionLink("Details", "ProjectDetails", new { basePath = @item.basePath })*@
</td>
</tr>
}
}
</table>
</fieldset>
</div>
