I try use this solution
http://www.telerik.com/community/forums/aspnet-ajax/treeview/allowedit-ignored-in-radtreeview.aspx
but this does not load ParentNodes..
How I can set this??
regards,
this is my code (i do all by code)
public UpdatePanel CreateTreeViewObject(Page pg)
{
UpdatePanel updatePanel = new UpdatePanel {ID = "upTreeView", UpdateMode = UpdatePanelUpdateMode.Always};

new RadTreeNode(_resources.GetString("Workspace", new CultureInfo(_culture)))

AllowEdit = false,
AllowDrag = false,
AllowDrop = false,
ContextMenuID = "MainContextMenu",
Value = "0"
