Is there a way to find out which elements a certain element overlaps?

Question

I have a custom canvas that allows elements to be dragged. However I do not want to allow elements to overlap.

Hi there,

you could perform a hit test using the VisualTreeHelper.HitTest method. Here's more info on that: http://msdn.microsoft.com/en-us/library/system.windows.media.geometryhittestparameters(v=VS.100).aspx
