Has anyone here got a sample (or can find one) of how to perform drag and
drop in SL4 using the basic events and logic? I presume that the necessary
code to do this is not a tangled nightmare. I have performed drag-and-drop
in WinForms apps many times, so I'd just like to know what the equivalent
code is in SL4.

 

All the samples I can find use the toolkit drop target which doesn't look
useful for me. It seems to have some miraculous behaviour whereby it "knows"
what to drop where. Only I know where things can be dropped.

 

I'm actually trying to allow a drag of a node in a ComponentOne TreeView
control to another TreeView. I have tried using the C1DragDropManager class
supplied by C1, but when I follow the sample code absolutely nothing
happens, no events are raised. To make things worse, the samples from C1 are
really unclear and they don't describe the absolute basics such as when the
class can be used and what can be dragged in what circumstances. This is
typical of 3rd party kits which are convoluted beyond belief.

 

As you can tell, I'm getting pretty frustrated as I've spent almost 2 solid
hours now stuffing around with C1 classes and searching the web without
success.
