Normally, if you select an item in the treeview, the element is adorned with a pink border. I have one app however where this feature has stopped working. What could cause this?
The app shows a world map that consists of a large number of canvasses and polygons. The one thing I thought could cause this, was the Panel.ZIndex that is set on certain shapes.
Ctrl-Shift click to select an element works perfectly, but the pink border never appears.
The following is in the trace file if that helps:
System.Windows.ResourceDictionary Warning: 9 : Resource not found; ResourceKey='noBreakpointDrawingImage'
