e.Node.Selected

[Kjell]

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">
           </telerik:RadTreeView>

javascript:

function OnClientNodeClicking(sender, args) {

                  if (args.get_node().get_text() == "nameOfTheNode")

                  {

                     //cancel the click event

                      args.set_cancel(true);

                      //prevents selection of a node

                      args.get_node().set_selected(false);

                    

                  }

             }
