Replace confirm with radconfirm in drag-and-drop demo

[Paul J]

in the drag-and-drop Grid demo (http://demos.telerik.com/aspnet-ajax/grid/examples/programming/draganddrop/defaultcs.aspx) when dragging items to the Recyle Bin, it gives a regular confirm box. How would I replace this with a radconfirm box?

I've got it so far as that it shows the radWindow through the radconfirm call, but it doesn't give me a chance to say yes/no, and instead continues execution of removing the dragged items. how do I 'pause' the execution properly?

here's the code snippet from the demo that uses the regular confirm

var node = args.get_destinationHtmlElement();
                            if(!isChildOf('trashCan', node))
                            {
                                args.set_cancel(true);
                            }
                            else
                            {
                                if (confirm("Are you sure you want to delete this order?"))
                                    args.set_destinationHtmlElement($get('trashCan'));
                                else
                                   args.set_cancel(true);
                            }

and here's my similar code, but trying to use the radconfirm. I must be missing something?

var node = args.get_destinationHtmlElement();

                                      

           if(!isChildOf('trashCan', node))

           {

               args.set_cancel(true);

                                  

           }

           else

          {

              var callBackFn = function(arg) {

                  if (arg) {

                      args.set_destinationHtmlElement($get('trashCan'));

                  }

              }

          radconfirm("Are you sure you want to remove this user from the role?",callBackFn);

          return false;

          // if (radconfirm("Are you sure you want to remove this user from the role?",callBackFn))

         // args.set_destinationHtmlElement($get('trashCan'));                                                                              

         // else

         // args.set_cancel(true);

        }

Thanks for the help.

Hello Paul J,

Predefined RadWindow dialogs are built on HTML elements, CSS and JavaScript and they cannot block the execution thread of the browsers. We provide a solution (a simulation of blocking the thread) that works in many cases, but unfortunately it cannot be applied in your scenario, because in this case the thread have to be blocked really in order to achieve the desired result.

All the best,

Well that is disappointing.  Is there not a way I could adjust my scenario to accomplish a modal prompt when dragging items from a grid to the recycling bin for confirmation of deletion?

Hello Paul J,

As I mentioned in my previous reply, the thread in this scenario must be really blocked. The predefined dialogs only simulate blocking the execution thread and this is why you need to use the standard browser dialogs, instead of the predefined ones.
