Hello Yevgeniya,

I just answered your support ticket on the same subject. For convenience I paste my reply below:

Hello Yevgeniya,

I examined your project and reproduced the problem. I noticed however, that you are not actually closing the RadWindow, but submit the parent page from within the content one when the RadWindow is maximized. Note that when a RadWindow is maximized, we intentionally hide the scrollbars and what is actually happening is that the page is submitted (via Ajax) while these scrollbars are still hidden (e.g. there is a style on the parent page that hides the scrollbars). Because you are using Ajax and the page is not actually fully reloaded and there is nothing that would "tell" the RadWindow that it is closed so the scrollbars should be brought back, the problem occurs. That is why when you disable Ajax, the problem does not appear - the whole page is reloaded and the dynamically entered style for hiding the scrollbars is removed.

To fix the problem in the project that you sent me, all you need to do is to close the RadWindow properly - by using its close() method:

    
            function updateParent() { 
        
                GetRadWindow().BrowserWindow.updateByChild(); 
        
                GetRadWindow().close(); 
        
            }

If this doesn't help in your real scenario, try closing the window and then calling the code in the updateByChild() function with a small timeout.

I hope this helps.

    }
    function OnClientClose() {
        document.documentElement.style.overflow = "scroll";
    }
</script>

<telerik:RadWindow ID="RadWindow1" runat="server" VisibleStatusbar="False"
            EnableTheming="True" Height="250px" Width="750px" DestroyOnClose="True"
