Cancelling logout server event

[Katya]

Hi Telerik,

On Clicking the logout button, I am displaying a confirm box. If the user press yes, then logged out. I tried the following code in the OnClientClicked event but I am getting some sort of JavaScript error in IE. In Firefox nothing happen. Please inspect the below code and guide me.
function OnClientClicked(sender, eventArgs)
{
    eventArgs.set_cancel(!confirm("Confirm logout?"));
}

Thanks to all,
Katya

Hi Katya,

Try the same JavaScript code in the OnClientClicking client side event of the RadButton and it will work as expected. You are getting an error in IE because the eventArgs of OnClientClicked event does not have a set_cancel method.

JavaScript:

<script type="text/javascript">
    function OnClientClicking(sender, eventArgs) {
        eventArgs.set_cancel(!confirm("Confirm logout?"));
    }
</script>

Thanks,

Thanks. Got it working. But how those events differ, I didnt get? Can you make it clear?

Hi,

Please have a look at this documentation on RadButton client side events.

Thanks,
