How To Display A Confirmation Dialog And Cancel The Postback When Using A Telerik RadButton



TODO:

You are using a Telerik RadButton, and you want to display a Confirm Dialog, and capture the user pressing cancel, thus canceling the Postback.

 

SOLUTION:

    <!-- Define button, and put method to call in the OnClientClicking event -->

    <telerik:RadButtonID="btnDelete"runat="server"Text="Delete Customer"OnClick="btnDelete_Click"

        OnClientClicking="ConfirmDelete">

    </telerik:RadButton>

   

    <!-- Confirm action here.  Cancel press in this dialog will return FALSE, which in turn we will catch and set cancel = true in the args -->

    <telerik:RadCodeBlockID="RadCodeBlock1"runat="server">

        <scripttype="text/javascript">

            function ConfirmDelete(sender, args) {

                if (!confirm('Delete Customer, do you wish to proceed?')) {

                    args.set_cancel(true);

                }

            }

        </script>

 

    </telerik:RadCodeBlock>

 

NOTES:

You may not need the RadCodeBlock, I did in this case due to Application
