Disable only the root Node or Root Node should be non clickable

[Goutham]

Hi There,

I have treeview with 2 and 3 level sub node. On click of each node i am loading the iframe on right side. i want disable the clicking of root nodes because on click of root nodes nothing should happen.Is it possible to disable the root node clicking or just disable the root nodes
and also the treeview is fullExpanded state.

Hello Goutham,

You can cancel the event when clicking on the root node like below.

ASPX:

<telerik:RadTreeView runat="server" ID="RadTreeView1" OnClientNodeClicking="ClientNodeClicking">
    <Nodes>
        <telerik:RadTreeNode runat="server" Text="Australia" Value="RootItems">
            <Nodes>
                <telerik:RadTreeNode runat="server" Text="Sidney">
                </telerik:RadTreeNode>
                <telerik:RadTreeNode runat="server" Text="Brisbane">
                </telerik:RadTreeNode>
            </Nodes>
        </telerik:RadTreeNode>
       </Nodes>
</telerik:RadTreeView>

Java Script:

<script type="text/javascript">
    function ClientNodeClicking(sender, args) {
       if (args.get_node().get_text() == "Australia") {
           args.set_cancel(true);
        }
   }
</script>

Thanks,
Princy.

Hey Princy,

Thanks for the reply. I am using radtreeview 6.3.8.0 assembly in this OnClientNodeClicking is not there
AfterClientClick or BeforeClientClick is available.
