MVC Dashboard Using AngularJS And Web API



Introduction 

In this article, we will see in detail how to create a dynamic MVC dashboard display using AngularJS and Web API. Using this web application, you can write your own SQL query to bind dynamic dashboard. This program makes your work easy to display any Table/ Columns details with your entered where condition, Order BY and with Group By option for the selected database on your home page. 

Features in Shanu MVC Dashboard


  1. Dynamic SQL Query:
  2. Column Names:
  3. Table Names:
  4. Where Condition:
  5. Group By:
  6. Order By:

Here, we will see details of each part,

1. Dynamic SQL Query

We can bind any data on our Dashboard page by entering our Select Query in this text box. We can also write our join query to display data from more than one table with where conditions. We need to first check the Is Query Checkbox for displaying our Dynamic SQL Query data on the dashboard page. If the check box is not checked then by default we will display the column and table details which we have given.



We can see from the above image, first we display the simple select query result in our dashboard page. Next, we display the combination of 2 table data using left outer join select query which will display UserName, UserType, Phone, Address, Email from userDetails and userAddress table. Here you can write your own SQL select query to display data with your where condition, Group By, Order By or Union or any other select query to be displayed. 

Note In this article, we can find the sample database and table creation query in code part. Before running this application kindly run the code part SQL script to create sample database and table with insert record for testing the output in our MVC dashboard page.

Sample Select query to be used for our application:
  1. select ID,ItemNo ,ItemName ,Comments ,Price from ItemDetail where Price>'1000'  
  2. select A.UserName,A.UserType,A.Phone,B.Address,B.Email  
  3. From  
  4. Userdetails A Left Outer JOIN UserAddress B  
  5. on  
  6.   
  7. A.UserID=B.UserID  
Here in this application we have option only to select and bind the data. If user entered any insert, drop, delete query, other than select query we will see the alert message as only select query can be used from this application. We have checked SQL Injection in each user input and display the error message to the user. We will see more in detail about this SQL injection checking in this article.

Note: Now we have fixed for only one database, we can select any table dada from the given Database name in our web config.

2. Column Names & 3) Table Name

Next we have another option to display the data by entering specific column or all columns to be displayed from the user entered tables .here user no need to write the complete Select SQL query. Here we can first write all our column names with comma and then write our table name for the given column details. We can also write our join query here by giving all the join column name details in the Column Names and join table name details with on Condition on the Table Name input. Here we can see a sample output for column and table details.



Sample Column Name and table details to be used for testing:
  1. Column Names: UserName, UserType, Phone

    Table Names: UserDetails

  2. Column Names: A.UserName, A.UserType, A.Phone, B.Address, B.Email

    Table Names: Userdetails A Left Outer JOIN UserAddress B on A.UserID=B.UserID
3. Where Condition

Now let’s see how to write our where condition for the given column and table details. If user need to add some condition using then they can add there condition same like we write in our SQL query to add more conditions we can use and key word. Here in the following image we can see the output of using where condition in our dashboard page.
 
 
 
Sample Column Name and table details with where condition to be used for testing:
  1. Column Names: ItemName, Price

    Table Names: ItemDetail

    Where Condition: Price>'4000'

  2. Column Names: ItemNo, ItemName, Comments, Price

    Table Names:ItemDetail

    Where Condition: ItemName like 'm%'

5. Group By

To use the Group By for our given column and table details user needs to check the Group By checkbox. In the Group By text box user can enter the column details for Group By. Here, we can see a sample output using Group By for the given column and Table details. Here, we can see as we have used both where condition and also unchecked the where condition to display the dynamic data with condition using Group By keyword.
 

Sample Column Name and table details with where condition and Group By to be used for testing:

  1. Column Names: ItemName,Price

    Table Names: ItemDetail

    Where Condition: Price>'4000'

    Group By: ItemName
6. Order By

To use the Order By for our given column and table details user need to check the Order By checkbox. In the Order By text box user can enter the column details for displaying the data in any order as ascending or in descending. Here, we can see a sample output using Order By for the given column and table details.
 


Sample Column Name and table details with Order By:
  1. Column Names: ID, ItemNo, ItemName, Comments, Price

    Table Names: ItemDetail

    Order By: Price desc

SQL Injection checking in user entered select query

 
We have also checked for the SQL Injection before executing user entered SQL Select query. We have created an array list to add all SQL injection string and we will be checking any of the array word matching with user entered select query. For example, we can see the above image as after select query we have entered drop query. But when we click on Search button, we display the message as drop is not accepted in select query.
 
Here is the list of SQL Injection string we have used in our application, You can add or remove as per your requirement. 
  1. // Array value to check for SQL Injection  
  2. $scope.sqlInjectionArray = ['create', 'drop', 'delete', 'insert', 'update', 'truncate',  
  3.                                 'grant', 'print', 'sp_executesql', 'objects', 'declare',  
  4.                                 'table', 'into', 'sqlcancel', 'sqlsetprop', 'sqlexec',  
  5.                                 'sqlcommit', 'revoke', 'rollback', 'sqlrollback', 'values',  
  6.                                 'sqldisconnect', 'sqlconnect', 'system_user', 'schema_name',  
  7.                                 'schemata', 'information_schema', 'dbo', 'guest', 'db_owner',  
  8.                                 'db_', 'table', '@@', 'Users', 'execute', 'sysname', 'sp_who',  
  9.                                 'sysobjects', 'sp_', 'sysprocesses', 'master', 'sys', 'db_',  
  10.                                 'is_', 'exec', 'end', 'xp_', '; --', 'alter', 'begin', 'cursor',  
  11.                                 'kill', '--', 'tabname', 'sys'];

Step 2: Create your MVC Web Application in Visual Studio 2015.

After installing our Visual Studio 2015, click Start, then Programs and select Visual Studio 2015 - Click Visual Studio 2015. Click New, then Project, select Web and then select ASP.NET Web Application. Enter your project name and click OK.

 
 
 Select MVC, WEB API and click OK.

  

Now we have created our MVC Application. Next, we add our connection string in our Web.Config file. Here, we are not using Entity Framework. We will directly get the data from our MVC Web API controller method using normal ADO.NET method. 

  1. <add name="dashboard" connectionString="Data Source=SQLSERVERNAME;Initial Catalog=DashboardDB;Persist Security Info=True;User ID=UID;Password=PWD" providerName="System.Data.SqlClient" />  
Kindly update with your SQL Server connection.

Step 3: Add web API Controller

Right click Controllers folder, click Add and then Controller.

 

Here, we will add a Web API Controller to be used for our AngularJS.

Select Web API 2 Controller – Empty and click Add. After that enter the controller name as DashboardAPIController

 

Get Method

Use the Http Get method to get all our dynamic data from database using normal ADO.NET method.

  2. public string getDashboardDetails(string sqlQuery, string columnName, string tableNames, Nullable<int> isCondition, string conditionList, Nullable<int> isGroupBY, string groupBYList, Nullable<int> isOrderBY, string orderBYList)

Step 4: Creating AngularJS Controller

Firstly, create a folder inside the Script folder and we give the folder name “MyAngular”

Now add your Angular Controller inside the folder.

Right click the MyAngular Folder and click Add and New Item, Select Web, then select AngularJs Controller and give name to Controller. We have given my AngularJS Controller as “Controller.js”

 
 
If the AngularJS package is missing, then add the package to your project.

Right click your MVC project and click Manage NuGet Packages. Search for AngularJS and click Install.

 

Modules.js: Here we will add the reference to the AngularJS JavaScript and create an Angular Module named “AngularJs_Module”. 
  1. // <reference path="../angular.js" />    
  2. /// <reference path="../angular.min.js" />     
  3. /// <reference path="../angular-animate.js" />     
  4. /// <reference path="../angular-animate.min.js" />     
  5. var app;  
  6. (function () {  
  7.     app = angular.module("dashbordModule", ['ngAnimate']);  
  8. })();  
Controllers: In AngularJS Controller we have done all the business logic and returned the data from Web API to our MVC HTML page.

1. Variable declarations

Firstly, we declared all the local variables need to be used. 

  1. app.controller("AngularJs_Controller", function ($scope, $filter, $timeout, $rootScope, $window, $http) {  
  2.     $scope.date = new Date();  
  3.     $scope.MyName = "shanu";  
  4.   
  5.     $scope.isQuerys = false;  
  6.     $scope.Querys = "";  
  7.     $scope.ColumnNames = "UserName,UserType,Phone";  
  8.     $scope.TableNames = "UserDetails";  
  9.   
  10.     $scope.isCondition = false;  
  11.     $scope.whereCondition = 0;  
  12.     $scope.Conditions = "";  
  13.   
  14.     $scope.isGroupBy = false;  
  15.     $scope.GroupBy = 0;  
  16.     $scope.GroupBys = "";  
  17.   
  18.     $scope.isOrderBy = false;  
  19.     $scope.OrderBy = 0;  
  20.     $scope.OrderBys = "";  
  21.     // Array value to check for SQL Injection  
  22.     $scope.sqlInjectionArray = ['create', 'drop', 'delete', 'insert', 'update', 'truncate',  
  23.                                 'grant', 'print', 'sp_executesql', 'objects', 'declare',  
  24.                                 'table', 'into', 'sqlcancel', 'sqlsetprop', 'sqlexec',  
  25.                                 'sqlcommit', 'revoke', 'rollback', 'sqlrollback', 'values',  
  26.                                 'sqldisconnect', 'sqlconnect', 'system_user', 'schema_name',  
  27.                                 'schemata', 'information_schema', 'dbo', 'guest', 'db_owner',  
  28.                                 'db_', 'table', '@@', 'Users', 'execute', 'sysname', 'sp_who',  
  29.                                 'sysobjects', 'sp_', 'sysprocesses', 'master', 'sys', 'db_',  
  30.                                 'is_', 'exec', 'end', 'xp_', '; --', 'alter', 'begin', 'cursor',  
  31.                                 'kill', '--', 'tabname', 'sys'];  
Search Method

In this method we call on search button click. Here we check for all the validation of user entered data before passing all the parameter to our Web API method. In this method we have commented for each condition checking. 

  1. //search Details    
  2. $scope.searchDetails = function()  
  3. {  
  4.     // 1. Check for Select Query -> In this fucntion we check for SQL injection in user entered select query if any key word from the array list is found then we give msg to user to entert he valid select query

  141. }  

Main Search Method

Finally after validation we call our main bind method to pass all the parameter to our Web API to get the dynamic data from the database. 

  1. // Main Select and Bind function    
  2. //All query details entered by user after validation this method will be called to bind the result to the Dashboard page.    
  3. function searchTableDetails(sqlQuery, columnName, tableNames, isCondition, conditionList, isGroupBY, groupBYList, isOrderBY, orderBYList)  
  4. {  
  5.     $http.get('/api/DashboardAPI/getDashboardDetails/',  
  6.     {  
  7.         params:  
  8.         {  
  9.             sqlQuery: sqlQuery,  
  10.             columnName: columnName,  
  11.             tableNames: tableNames,  
  12.             isCondition: isCondition,  
  13.             conditionList: conditionList,  
  14.             isGroupBY: isGroupBY,  
  15.             groupBYList: groupBYList,  
  16.             isOrderBY: isOrderBY,  
  17.             orderBYList: orderBYList  
  18.         }  
  19.     }).success(function(data)  
  20.     {  
  21.         $scope.dashBoadData = angular.fromJson(data);;  
  22.         //alert($scope.dashBoadData.length);    
  23.         //if ($scope.dashBoadData.length > 0) {    
  24.         //}    
  25.     })  
  26.     .error(function()  
  27.     {  
  28.         $scope.error = "An Error has occured while loading posts!";  
  29.     });  
  30. }  

Step 5: HTML part to bind all our dynamic result for the Dashboard

Next in our MVC View page we design our dashboard page and bind all the dynamic data at runtime. 

  1. <html data-ng-app="dashbordModule">  
  2. @{ ViewBag.Title = "Shanu Dashboard"; }  
  3.   
  4. <body data-ng-controller="AngularJs_Controller">  
  5.   
  6.     <table style='width: 99%;table-layout:fixed;'>
