  54.     <tr class="hyperlink">  
  55.         <td style="color: Blue;">  
  56.             @{  
  57.                 var grid = new WebGrid(source: Model.EmployeeModelcollection, rowsPerPage: 10);  
  58.             }  
  59.             @grid.GetHtml(  
  60.                          tableStyle: "gridTable",  
  61.                          headerStyle: "gridHead",  
  62.                          footerStyle: "gridFooter",  
  63.                          rowStyle: "gridRow",  
  64.                          alternatingRowStyle: "gridAltRow",  
  65.                             columns: grid.Columns(  
  66.                             grid.Column("Title", header: null, format: @<text>  
  67.                                 <input type="radio" id="rbtemployee" onclick="javascript:SingleRadiobuttonSelection(this.id)" /></text>),  
  68.                                      grid.Column("Name", "Name"),  
  69.                                  grid.Column("City", "City"),  
  70.                                      grid.Column("Contact", "Contact")  
  71.               )  
  72.          )  
  73.         </td>  
  74.     </tr>  
  75. </table>   

Step 5

Execute the application. It looks like this:

Here we see that all the radio buttons are selected.

If you want to select only one radio buttons then perform the following changes in the index.cshtml file.

We add the name tag in the radio button.

<input type="radio" id="rbtemployee" name="employee" onclick="javascript:SingleRadiobuttonSelection(this.id)" /></text>),

Now execute the application and the output will be:
