How to add a "confirm delete" option in ASP.Net Gridview?

Ok lets say you do have a grid with a button inside template column

<asp:Button ID="btnSave" runat="server" Text="Save" OnClientClick="return check();" />

and write in your check function determine if button should raise a postback?

<script type="text/javascript">

function check() {

  var doINeedToAskUserConfirmation =  // Get this according to your needs
  if ( doINeedToAskUserConfirmation  ){
      return confirm("Are you sure?");
  }
  return true;
}

</script>

lets say you have a button

<input type="button" id="btnConfirm" value="Proceed"/>

Make an ajax call to determine if you need any confirmation.

$("#btnConfirm").click(function(){

   $.ajax({
     type: "POST",
     url: "some.ashx",
     data: { name: "John", location: "Boston" }
  }).done(function( response ) {
     // lets say when response is true we will ask confirmation
     if ( msg )
     {
        var c = confirm( "All record will be deleted. Are you sure ? ");
        // Do another ajax call to complete your operation
     }
  });


});
