OnClientNodeExpanding not working in RadTreeView

[Abhishek]

Hi,

I have a RadTreeView in a web page. I want to handle the event when '+' is clicked to expand a node.
When I try to handle it on server side it works fine.
But when I try to handle this event in JavaScript using OnClientNodeExpanding it does not work.
Please help.

Abhishek Jain

Hello Abhishek,

Have you tried correct method to attach the OnClientNodeExpanding event, that is without including brackets with handler name?

Check out the example:
aspx:

<telerik:RadTreeView ID="RadTreeView1" OnClientNodeExpanding="OnClientNodeExpanding"
     runat="server" CheckBoxes="True" ShowLineImages="False">
   . . .

client code:

<script language="javascript" type="text/javascript">
    function OnClientNodeExpanding(sender, args) {
        alert("OnClientNodeExpanding fired");
    }
</script>

Could you paste the code that you tried?

clien code

<script language="javascript" type="text/javascript">

Hi Abhishek,

Which control exactly you're using - RadTreeView for ASP.NET or RadTreeView for ASP.NET AJAX?

All the best,

Hello Abhishek,

I've tested the event again and it's fired without a problem. Please send us a simple page where the erroneous behavior occurs. Thanks
