But after I changed my plugin from a WPF window to Rhino Panel, this OnDrop event can never be fired again. I wonder if anyone knows if WpfElementHost is doing something under the hood that makes it different?
If so, what would be correct way to implement OnDrop event listener?
Sorry to bother you again. Maybe the above example is not good enough. Would it be possible to provide a sample code on how to drag and drop items between two listBoxes in a rhino panel? I can’t find any examples in your official Github.
