What I have is a Grid with each cell containing its own canvas. I have a UserControl (uc) that I want to be able to drag/drop to other cells within grid. I was able to get my drag/drop of the uc working except for the error in the subject.
On a drag/drop of a uc, I determine the canvas the drag started in, get a reference to the uc, clear the original canvas's children and add the uc to the new canvas. The wierd thing about this error is that it is not entirely consistent. Sometimes,
I can drag the uc around to three or four different cells before receiving the error. I have read multiple posts about this error but I don't seem to be able 'disconnect' the uc from its original logical parent. Help is appreciated.
