ASP.NET

Check/Uncheck All GridView Checkboxes With jQuery

GridView is a very important control in ASP.NET, and at times, we are required to do the check and uncheck of all the child checkboxes with a parent checkbox. This parent checkbox is usually located inside the header of GridView. This feature can be achieved with just 2 lines of jQuery code. Let me show you how to do it.

GridView Code

First, in your GridView, you have to create a ‘Template Field’. Inside this, you have to create 2 things - ‘Header Template’ and ‘Item Template.’

Add a checkbox inside the ‘Header Template’ and give it an Id (‘rowCheckbox’). Add another checkbox inside the ‘Item Template’ and give it an Id (‘childCheckbox’).

The below GridView code shows what I mean.

  1. <asp:GridView ID="gridView" runat="server" AllowPaging="true" PageSize="10" OnPageIndexChanging="gridView_PageIndexChanging">  
  2.     <Columns>  
  3.         <asp:TemplateField>  
  4.             <HeaderTemplate>  
  5.                 <asp:CheckBox ID="rowCheckbox" runat="server" /> </HeaderTemplate>  
  6.             <ItemTemplate>  
  7.                 <asp:CheckBox ID="childCheckbox" runat="server" /> </ItemTemplate>  
  8.         </asp:TemplateField>  
  9.     </Columns>  
  10. </asp:GridView>   

C# Code where GridView is bound with Data

  1. List<Products> products;  
  2. protected void Page_Load(object sender, EventArgs e)  
  3. {  
  4.     if (!IsPostBack)  
  5.         BindGridView();  
  6. }  
  7.   
  8. void BindGridView()  
  9. {  
  10.     LoadData();  
  11.     gridView.DataSource = products;  
  12.     gridView.DataBind();  
  13. }  
  14. void LoadData()  
  15.     {

  121. {

  123.     BindGridView();  
  124. }  

Here, I am binding GridView from a Class data instead of Datatable. You can understand how it is done by reading - How to Bind GridView with Class instead of DataTable.

jQuery Code

Now, add the jQuery Check Checkbox code that will check all the Child Checkboxes that have id (‘childCheckbox’) when the Parent Checkbox (with id ‘rowCheckbox’) is either checked or unchecked.

Add the jQuery code to your page.

  1. <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>    
  2. <script type="text/javascript">    
  3.     $(document).ready(function () {    
  4.         $("[id *= rowCheckbox]").click(function () {    
  5.             checkChildCheckbox(this);    
  6.         });    
  7.     
  8.         function checkChildCheckbox(rowCheckbox) {    
  9.             $("[id *= childCheckbox]").prop("checked", $(rowCheckbox).prop("checked"));    
  10.         }    
  11.     });    
  12. </script>    

The 2 lines of jQuery doing this magic are -

  1. checkChildCheckbox(this);  
  2. $("[id *= childCheckbox]").prop("checked", $(rowCheckbox).prop("checked"));  

Modifying the Code

The above code will work perfectly; but if the GridView has paging, then you will find your checkboxes not retaining their values on page navigation.

To make the Check/Uncheck feature in GridView to work, you have to store the parent checkbox’s selection inside a hidden field.

So first, create a hidden field in your page.

  1. <input type="hidden" id="checkBoxHidden" runat="server"/>  

Then, modify the jQuery code with the following new one.

  1. <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>  
  2. <script type="text/javascript">  
  3.     $(document).ready(function () {  
  4.         var booleanValue = ($("[id *= checkBoxHidden]").val() === "true");  
  5.         $("[id *= rowCheckbox]").prop("checked", booleanValue);  
  6.         $("[id *= childCheckbox]").prop("checked", booleanValue);  
  7.           
  8.         $("[id *= rowCheckbox]").click(function () {  
  9.             checkChildCheckbox(this);  
  10.         });  
  11.   
  12.         function checkChildCheckbox(rowCheckbox) {  
  13.             $("[id *= childCheckbox]").prop("checked", $(rowCheckbox).prop("checked"));  
  14.             $("[id *= checkBoxHidden]").val($(rowCheckbox).prop("checked"));  
  15.         }  
  16.     });  
  17. </script>  

So now, the Check/Uncheck feature will also work on GridView paging.
