RadWindow confirm close handling

[Steve Holdorf]

I have a RadWindow that has a custom button that performs a save and close. This works fine. Now, what I am trying to do is display a javascript close confirm dialog when the user selects the top right close X button. I saw the article about the radConfirm method and adding add_beforeClose(onBeforeClose) techniques. In my case I have had no luck with either. Can you recommend a way to do this?

Thanks,

I found your example (see below) but am getting the javascript runtime error: Object expected on the radConfirm call.

<script type="text/javascript">

  function onBeforeWindowClose(oWinow, args)
  {
   function callbckFunction(confirmResult)
   {
    if (confirmResult)
    {// confirmResult == true
     // Close this RadWindow

     // First remove the handler in order to avoid recursion
     oWinow.remove_beforeClose(onBeforeWindowClose);

     // Close the window
     oWinow.close();

     // Reattach the handles after the window is closed.
     // RECOMMENDATION: If the DestroyOnClose="true" property is set in in the RadWindow's declaration,
     // then remove this line of the code:
      oWinow.add_beforeClose(onBeforeWindowClose);
    }
    else
    {// confirmResult == false
     radalert("Closing is canceled");
    }
   }

   // Cancel closing
   args.set_cancel(true);

   // Show a rad confirmation dialog
   radconfirm("Are you sure ?", callbckFunction, 400, 200, null, "Rad Confirm");
  }

  function GetRadWindow()
  {
   var oWindow = null;
   if (window.radWindow)
    oWindow = window.radWindow;
   else if (window.frameElement.radWindow)
    oWindow = window.frameElement.radWindow;
   return oWindow;
  }

  function pageLoad()
  {
   // Get the RadWindoiw object that contains this page
   var oWindow = GetRadWindow();

   // Attach RadWindow's OnClientBeforeClose handler
   oWindow.add_beforeClose(onBeforeWindowClose);
  }

  function pageUnload()
  {
   // Get the RadWindoiw object that contains this page
   var oWindow = GetRadWindow();

   // NOTE! If the DestroyOnClose="true" is set in the RadWindow's declaration,
   // then the oWindow object will be 'null'.
   if (oWindow)
   {
    // Detach RadWindow's OnClientBeforeClose handler
    oWindow.remove_beforeClose(onBeforeWindowClose);
   }
  }

</script>

Hello Steve,

If you need to call radconfirm(), radalert(), radopen(), etc. RadWindowManager's functions, you must have a RadWindowManager control present on the page where the script is executed.
