Hallo Doug!
Thankyou for your answer. It took a while before I understood everything, but now I think I know how it works.
But I have a problem with the HitTest method. I allways get a logic .T. back, never a nodereference.
I have tried to use the HitTest method before, and it doesnt matter what value there is on X and Y, I allways get a .T. in return. (Maybe I have got a .F. back sometime, but never a nodereference.
I dont know what is wrong.

I must release the button over node 3 so the information in "selecteditem" can change to node 3.

In that case, you should use the TreeView's HitTest method to determine which node is being dragged. HitTest expects you to pass it the X and Y coordinates of the mouse, but those values must be in twips (1/1440th of an inch) rather than pixels. So, first you have to know how to converts twips to pixels and pixels to twips. Here is code that determines how to do that (it assumes there are nTreeFactorX and nTreeFactorY properties of the class this method code is in):

Now in the TreeView's MouseDown method, you can do something like this:
>

loNode = This.HitTest(nXCoord * Thisform.nTreeFactorX, ;
>  nYCoord * Thisform.nTreeFactorY)
>* do something with loNode, such as storing it in a property
