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.
You have to set AllowDrop to true
I have attached a zip file to this post (zipped using WinZip 12.0)
I don't have a .RAR extractor, please zip the sample if possible.
