    I have a RadWindow appear and load another page in my project when I click a button. However, when the RadWindow loads on top of an ActiveX control I have embedded in the main page, the border is behind the ActiveX control while the contents remain in the foreground. Now, I am unable to drag, resize, close, etc. the RadWindow. I've noticed that a lot of the RadControls work this way. Undocked RadDocks disappear behind ActiveX controls when you drag them over them. The DropDown list (if big enough to extend to the ActiveX control) will also disappear behind it.

    Is this a known issue? Is there a fix or a workaround? Because the ActiveX control is critical to our project. And I currently see no way around this problem.

    Thank you.

    Hey Andrew,

    Have you tried changing the z-index of the RadWindow to see if that forces it above the ActiveX control? I know Window and Dock have pretty low z-index values (as seen here in the documentation), however I'm not sure how ActiveX controls handle z-index or if they ignore it and do their own thing. 

    I did find this article from Microsoft about setting activeX controls, and it shows that you can set a Z-Index on them...  So there might be hope yet!

    Please let us know if this works as I'm kinda curious, but I've never touched ActiveX so I can't test this theory out.

    The solution to this problem, in case anyone wants an answer in the future, is to set the Overlay property of the RadWindow to "true."
