Disable Node click for Particular Node Level

[Phaneendra]

Hi,

I have a RadTreeView, binded from database of 5 Levels.
Handling the Node click from client side, now I'm facing an issue, if the Node level is 2 I have to block the node click no post back should happend when user clicks on that node.

Hi Krishna,

Try the following code to block the node click from client side.

JS:

<script type="text/javascript">
    function OnClientNodeClicking(sender, args)
    {
        if (args.get_node().get_level() == 2)
            args.set_cancel(true);
    }
</script>

Thanks,
Shinu.

Hi Krishna,

Here is the code that worked for me as expected.

ASPX:

<telerik:RadTreeView ID="RadTreeView1" runat="server" DataTextField="name" DataFieldID="id" DataSourceID="SqlDataSource1" DataFieldParentID="parent" OnClientNodeClicking="OnClientNodeClicking">
</telerik:RadTreeView>

JS:

<script type="text/javascript">
    function OnClientNodeClicking(sender, args)
    {
        if (args.get_node().get_level() == 2)
            args.set_cancel(true);
    }
</script>

Please provide your full code if it doesn't helps.

Thanks,
Shinu.

This solution works partially. So set_cancel(true) in node clicking correctly prevents postback but also prevents the node from being selected.
Adding args.get_node().set_selected(true);  in the function selects the node.
