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.
tv.AllowDragDrop = true;
tv.DataSource = _subOptions;
tv.DisplayMember = "optionDesc";
tv.ValueMember = "OptionID";
According to the documentation, this simple example should work. Any idea why it doesn't?

In the latest version of RadTreeView (Q1 2011 11.315), we shipped sort and filtering support which constrains the possibility to do drag and drop operation in bound mode. This operation is valid only for unbound mode, if sorting and filtering functionalities are not performed.
