From my reading of this line "
When you are using the RadBusyIndicator control you always have to set its Content property. This will be the content on top of which you want to visualize the RadBusyIndicator control." in this article http://www.telerik.com/help/silverlight/radbusyindicator-getting-started.html I mocked up this quick demo to see if I could use it. WPF app loads a window. In the window is a frame which loads a page. On that page is a button that when clicked puts the thread to sleep for 3 seconds. In that button I get a handle to the parent window and set the IsBusy to true....but it never shows. I've tried numerous variations but I can't get it to work in my project or my mockup??
Main Page cs
I'm sure it works so I must be doing something wrong?
