Query: Ajax call back on tree node check uncheck

[Hemangajit Dutta]

Hi,
     Greetings. We are using Telerik Treeview with check box functionality. We need to make some Ajax calls when we uncheck the check box for doing some validations. Can you please provide me with some code sinppets on how to achieve that functionality.

Thanks

Hi Hemangajit,

Have you tried attaching OnClientNodeChecking/OnClientNodeChecked client events and invoke the Ajax call?

JavaScript:

<script type="text/javascript">
function OnClientNodeChecking(sender, args)
{
    if(args.get_node().get_checked())
    {
        alert("UnChecking");
        // Ajax call
    }
}
</script>
