I have a scrollViewer with an ItemsControl (which holds rows with data) as content. The data from these rows is grabbed from the server so I want to display a ProgressRing with a text until the data arrives. Basically I want the content of the ScrollViewer to be a grid with progress ring and a text and after the data arrives the content to be changed with my ItemsControl.
The problem is that the ScrollViewer does not accept more than 1 element as content. Please tell me how can I solve this problem. (I'm a C# beginner)
