Telerik.Web.UI.TreeListDragDropColumn

TreeListDragDropColumn is used for utilizing items drag and drop operation in RadTreeList.
It renders a drag handle which can be used to get hold of the item and drag it around.
When this column is used, an item can be dragged only if the drag handle is clicked.
Note that item selection still needs to be enabled in order for the handle to be active.
