  • Create another JavaScript file and name it as Controller.js.
  • Start writing code as given below.
    1. app.controller("gridController", function($scope, $rootScope) {  
    2.             var data = [];

  • Here, we have static JSON data in the same way you do with the db data.
  • Data is in the form of array objects.
  • In every column object, we have multiple key value pairs.
  • In the object showTags, the key is used to merge multiple boolean columns into one column as tags.
  • showColumns is used for show and hide of columns.
  • Other keys serve the same purpose as the name given to them.
  • $rootScope is available globally in the whole application that is we can set rootscope in 1 controller and access the value in other controller with rootscope.
  • we store the array of columns in $scope.columns and array of data in $rootScope.gridData.
  • We are going to access these in View for binding of data.
In the Index view of home controller, start writing the following code. 
  1. <html ng-app = "myApp">
  2. <body>
  3. <div class="table-responsive" ng-controller="gridController">  
  4.    <table class="table table-striped table-bordered table-hover dataTables-example">  
  5.       <thead>  
  6.          <tr>  
  7.             <th ng-repeat="column in columns" width="{{column.width}}" ng-if="column.showColumns == 'true' && column.dataType != 'commands' && column.dataType != 'bool'">  
  8.                <b>{{column.key}}</b>  
  9.             </th>  
  10.             <th ng-repeat="column in columns" ng-if="column.dataType == 'bool' && column.showColumns=='true'" width="5%">Tags</th>  
  11.             <th aria-sort="descending" ng-repeat="column in columns" width="{{column.width}}" ng-if="column.showColumns == 'true' && column.dataType == 'commands'">{{column.key}}</th>  
  12.          </tr>  
  13.       </thead>  
  14.       <tbody>  
  15.          <tr ng-class="{'primaryRow':rowIndex===key}" data-ng-repeat="(key,val) in gridData">

  28.                <span ng-hide="true">{{val[column.key]}}</span>

  • Put ng-app directive on html tag and ng-controller on div tag.
  • Here in the view we created key value pairs.
  • We automized the entire grid without hardcoding the name of single column in grid.
  • We use ng-repeat for automizing the entire json.

    • Columns are created by putting ng-repeat on th. Example : <th ng-repeat = "column in Columns">column.key</th>.
    • Show and hide the columns by putting column.showColumns key on tags.
    • We also put multiple conditions and set different styles by iterating.
    • It iterates as many times as number of keys in $scope.columns.
    • Similarly row data are created by iterating $scope.gridData with column key.Example : <tr ng-repeat="(key,val) in gridData"><td ng-repeat="column in Columns"> val[column.key]</td></tr>.
    • Include scripts in bundle config.cs.
  1. bundles.Add(new ScriptBundle("~/bundles/angular").Include(  
  2.                 "~/Scripts/angular1.5.5.min.js",  
  3.                 "~/Scripts/Module.js",  
  4.                 "~/Scripts/Controller.js"));  
  • Add this bundle in RegisterBundle method in BundleConfig.cs file.
  • Include bundle on layout page as given below.
  1. @Scripts.Render("~/bundles/jquery")  
  2. @Scripts.Render("~/bundles/bootstrap")  
  3. @Scripts.Render("~/bundles/angular") 

Now, run the application and get the result.
