MVC GridView - Implement the "Select All" Checkbox inside the SetHeaderTemplateContent

created 10 years ago

I have a MVC Grid View.  Inside the grid view header, I had kept the checkbox.  If I check or uncheck that checkbox, all the rows inside the grid is getting selected.

Where as, after selecting all the rows, If I uncheck any one of the rows, the header checkbox is not getting unchecked.

I had tried using Jquery, It is not working.

For your reference, I have attached a sample, please verify and let me know, how to achieve this functionalty.

Thanks for your help.

Hello,

In general, we recommend using the built-in "Select All" functionality. It does not require extra code. See the online Select All Rows demo regarding this.
To accomplish this task, you can also use the approach described in the How to implement check boxes with SelectRows and SelectAllRowsOnPage features in a grid's template example. Although it is designed for the web forms technology, the scenario remains the same. See the MVC GridView - "Select All" check box loses its "checked" state ticket for more details.
Let us know if you need further assistance.

      Thanks for directing me to the correct example.  I was able to accomplish the Select All Rows.  Please let us know, How to access the selected rows state in the controller?  Is there any predefined methods or how to I get those values in the controller.
      Thanks

        Hello,

        Thank you for informing me that the information was helpful.
        To access the selected rows state in the controller, perform the following steps:

        1. Get selected rows values via the client-side ASPxClientGridView.GetSelectedFieldValues method;
        2. Pass these values to a Controller via an option described in the Passing Values to Controller Action Through Callbacks help topic.
          See the How to get all GridView selected keys and pass them to a Controller example demonstrating this scenario.
