I'm facing an issue with the RadWindow control. If you attempt to drag the window during a postback and the server-side code attempts to close the window via script, the window closes and then re-appears. When the window re-appears, you are not able to close this window using the "X" icon.

Telerik Version: 2011.1.413.40.

Steps to Reproduce:
1. Click "Open Dialog" button.
2. Click "Submit" button in the window. This issues a Thread.Sleep(5000) in the Submit button click event to simulate a long-running task.
3. While the window is posting-back, drag the window around.
4. The window will close, via script from the server-side postback using ScriptManager.RegisterStartupScript to close the window using javascript similar to: "var radWindow = GetRadWindow(); radWindow.close();".
5. Observe that the window re-appears.
6. Now, attempt to close the window. You cannot close this dialog.

Hello Ryan,

I also tested your code and I was not able to replicate your behavior. What I can confirm is that there is an issue when you inject a call to the RadWindow's close() method from the code-behind and the DestroyOnClose property is set to true. This happens under IE9 only, as it changed a lot of the behaviors of the iframes and what we have found so far is that iframes do not dispose properly in this browser.

Your code results in the Sys is undefined error, just as Princy reported, and once a JavaScript error occurs on the page there is no guarantee how the page will function after that. For one thing - scripts are no longer executed and therefore you would, indeed, have no way to close the RadWindow.

The way to work around this IE9 bug is to either set the DestroyOnClose property to false, or to use the timeout:

setTimeout(function ()

{

radWindow.close(returnValue);

}, 0);

You can find a video from my experiment here: http://screencast.com/t/aMDwf46ry. Note that the error is not present in IE8 for example and that the timeout resolved it, which allows the RadWindow to be closed at will.

Thank you for the video. It was very helpful because I can see that I'm not explaining my issue clear enough. I have recorded a video as well for you to see. Also I am including my updated code as well. I included your recommendation for the setTimeout in the CloseModal script.

Here is the link to my screencast: http://screencast.com/t/fxLrEIatjXV4

In the video, after I click the Submit button on the Dialog.aspx, I then click and drag the window while the page is in a post-back and I do not release the window drag until after the window closes. You'll notice that the window re-appears after its been closed. I then attempt to close the window with the "X" in the upper right-hand corner. I am not able to close the window. Then, I attempt to "Submit" the dialog.aspx again hoping that my "CloseModal" script method will close the dialog. The window does not close.

My issue is not related to IE 9. I can duplicate the issue in IE7, IE8, and Google Chrome (14.0). I didn't try Firefox.

Here is my updated code.

Hi guys,

You can also check if the RadWindow is already closed in the OnClientDragEnd event and if so - make sure its popup element is hidden:

function OnClientDragEnd(sender, args)

{

if (sender.isClosed())

{

sender._popupBehavior.hide();

}

Where this function is, of course, attached to the OnClientDragEnd event of the RadWindowManager.

All the best,
