After upgrading to Q1 2011, drag and drop within a single treeview is no longer working in an existing project. The treeview is bound to a DataTable.
According to the documentation, this simple example should work. Any idea why it doesn't?
tv.AllowDragDrop = true;
tv.DataSource = _subOptions;
tv.DisplayMember = "optionDesc";
tv.ValueMember = "OptionID";
