telerik radMenu shows through to a radWindow

Question

I have a radMenu on the main site.master form which shows on a page. The page has a radGrid with a button to open a radWindows that shows a report. When the radWindow opens everything works great but the radMenu shows through onto the Window. How do I prevent the menu from showing through on the window.

Answer 1

The default RadMenu z-index is 7000 whereas the default RadWindow z-index is 3000 (reference here). Change the z-index of the RadMenu to be less than the RadWindow (or the contrary as you prefer).

<telerik:RadMenu runat="server" style="z-index: 2900" />

Answer 2

Julien is right - more info can be found here.

Note that if you use a RadWindowManager (instead of standalone RadWindow controls), you should set the z-index to the manager itself.
