    You can seamlessly populate RadTreeView from XML.

    • Loading from XML file 
      RadTreeView1.LoadContentFile("TreeView.xml");
    • Loading from XML string 
      RadTreeView1.LoadXml("<Tree><Node Text="Books"/><Node Text="Music"/></Tree>");

    You can also retrieve the current RadTreeView structure in XML format:

    • C# 
      string xml = RadTreeView1.GetXml();
    • VB 
      Dim xml as String = RadTreeView1.GetXml()
    • DefaultCS.aspx
    • DefaultCS.aspx.cs
    • TreeView.xml
