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()
  • DefaultVB.aspx
  • DefaultVB.aspx.vb
  • TreeView.xml
