Hi. I'm fairly new to this. I am trying to set up a RadTileView with a variable number of items. I have bound the ItemsSource to my ViewModel, set up the ContentTemplate as a grid, and can display each item fine. The only problem is that when there are too many items to fit on one row in the window they still lay themselves out as a single row and a horizontal scrollbar appears. What I want is for the items to wrap onto multiple rows with a vertical scrollbar if necessary. I'm sure this must be totally obvious but I can't seem to find the right setting to make it do this.
