WPF GRID to GRID drag and drop

Question

I am trying to find a way to drag and drop between two grids(NOT datagrids). Both grids have 3 columns and the second grid gets populated based on whats dropped from first grid and the rows on second grid are generated dynamically. First grid has custom controls as icons. I am unable to get the items on the first grid as row/column co-ordinates but the mouse event handler gives me the (x,y) point co-ordinatels. Is there an easy way of doing this?

Thanks.

If I understand correctly then the main problem you have is to get the control under your mouse cursor. You can get it by using either UIElement.InputHitTest or VisualTreeHelper.HitTest to get that control / visual. Also do check out this article on MSDN: Hit Testing in the Visual Layer - it is a well-written explanation of this process with examples.
