How can I determine if a Drag event is in progress when inside another event? Inside the tree's BeforeExpand event for example? The tree doesn't seem to have anything like an IsDragging or DragInProgress property.

Also, if this functionality is not supported and I have to track this myself (as I am currently), how can I tell when an invalid dragdrop has been completed?

Meaning, if I drag over an invalid target and release the mouse the dragdrop ends but no event is raised. Its like canceling, but QueryContinueDrag doesn't register anything useful and I can't find any way be notified when this happens. As a result I can't accurately track if the tree is in a dragging state or not.

I've handled all the other dragdrop potentialities but this one.

Hi Keith,

We are working over this issue.In the meanwhile you can try inserting a bool value in the source code of the control to track the dragging state of the TreeViewAdv control.
