    This works great except e.Node.Selected = False
    I try disable that you can click (select) on node 1 and 2, but it may not function?
    Help me :-)
    Protected Sub RadTreeView1_NodeDataBound(ByVal sender As Object, ByVal e As RadTreeNodeEventArgs)
        e.Node.ToolTip = (TryCast(e.Node.DataItem, DataRowView))("NodeId").ToString() & " + " & (TryCast(e.Node.DataItem, DataRowView))("ParentNodeId").ToString()
        e.Node.ImageUrl = "../images/caTree/" & (TryCast(e.Node.DataItem, DataRowView))("ImageUrl").ToString()
        e.Node.NavigateUrl = "../admin_dbpage.aspx?id=" & (TryCast(e.Node.DataItem, DataRowView))("NodeId").ToString() & "&db=ledare" & "&url=ledare/"
        e.Node.Target = "main"
        If (TryCast(e.Node.DataItem, DataRowView))("NodeId").ToString() = 1 Or (TryCast(e.Node.DataItem, DataRowView))("NodeId").ToString() = 2 Then
            e.Node.AllowDrag = False
            e.Node.Selected = False
        End If
    End Sub

    Hi Kjell,

    The selected property of a node can be used in a scenario when you need to have a specific node selected/not selected. I tested the scenario and once you set the selected to false, the node does not get selected on page load. However, as I understand from your scenario you are trying to make the node not selectable. You can use the AllowDrag property of a node if you need to disable the dragging of a specific node of the Enable="false" if you need to disable the node.   Another approach is to cancel the selection and the clicking of the specific node using the client-side approach with the OnClientNodeClicking event:
    <telerik:RadTreeView ID="RadTreeView1" runat="server" Skin="WebBlue" OnClientNodeClicking="OnClientNodeClicking" OnNodeDataBound="RadTreeView1_NodeDataBound" EnableDragAndDrop="true">

    function OnClientNodeClicking(sender, args) {
                      if (args.get_node().get_text() == "nameOfTheNode")
                         //cancel the click event
                          //prevents selection of a node
