How to achieve that just the top modal window is accessible?

Following problem. In my application you can open multiple modal windows. Every window is dependent on the previous opened window (hierarchical). Means that when a child window is opened, the user cannot drag this child window aside and interact with the parent window.

How can I achieve, that the surface behind the top child window freezes? I use RadWindow, by the way.

Solution

  • The key was the bool WindowBaseAutomationPeer.IsTopmost Property of the RadWindow class. Telerik Documentation
