Heya Silderado,

So... you're saying you open a RadWindow (I am guessing using RadWindow.Show() somewhere?), and when you close the window you get that error message?

Is there any way you can post the code you are using for the aspx/.cs that is involved?  Also, not sure if this helps at all, but here is a post with a similar problem that references a problem found in an older version of the control which was fixed in newer releases.  Do you have all the service packs for Q2?

[Silderado]

After closing the window when I try to perform any action the error occurs.

I'm using the service pack for Q2.

This post I had already checked and not helped me.

The code I'm using to open a new window:

   RadWindow Consulta = new RadWindow();
   Consulta.ID = "RadWindowManager1";
   Consulta.NavigateUrl = "Tela.aspx";
   Consulta.VisibleOnPageLoad = true;
   Consulta.Width = 550;
   Consulta.Height = 480;
   RadWindowManager1.Windows.Add(Consulta);

Hi Silderado,

The code that you posted looks OK and should not be the reason for such problem. At this point I cannot tell what is the exact reason for such error, but if you open a support ticket and send me a full sample project where this error can be reproduced, I will check it right away.

For any future people that might get this error, I found it was because I had a ScriptManager in both my popup window AND master page.  Removing the duplicate instance(s) of this (either asp:ScriptManager or RadScriptManager) so there was only one instance of it, which I kept in my master page, resolved this issue.
