Using a DockingManger that contains a Listbox in one pane and a GridView in a Document Pane. I have try to implement drag and drop from the Grid to the Listbox using code I have found here (http://www.telerik.com/community/forums/winforms/treeview/need-winform-example-drag-from-grid-to-treeview.aspx) but unable to implement. The Not Allowed drag Icon is shown when selecting a row and draging. Using Q1 2009 Winform controls. Any help greatly appreciated.
