  PROJECT DESCRIPTION
  The project shows how to support 'Undo' of Drag & Drop operations with RadTreeView.
  
  A Stack<string> is used to store the XML of the TreeView before each Drag & Drop operation. 'Undo' loads TreeView from the to XML in the Stack.
  
  Note: this technique can be used with every RadControl which supports the GetXml and LoadXmlString methods.
