Assuming you called DoDragDrop from the SelectionDragStart event, that should work. If you like you can attach a sample project to this article and we can try to figure out what is going on there.
OK, I've attached a sample project - it is in VS2008 format, let me know if you have a problem with this.
The attached project is the infragisitcs sample called "UltraTree Drag and Drop VB", *but* it has been modified such that the UltraTree is created at runtime rather than at design time.
You should note that the dragdrop feature does not work.
Thankyou for your assistance.
I don't have a .RAR extractor, please zip the sample if possible.
I have attached a zip file to this post (zipped using WinZip 12.0)
You have to set AllowDrop to true
