OnClientDataBound
This article demonstrates how you can use the OnClientDataBound event to execute a script when the data binding of RadSlider is finished.
The only parameter the event handler receives is the client-side object of the slider that fired the event.
You can check in Example 1 how this event can be used for notifying the user that the data binding of the slider is finished.
Example 1: Using the OnClientDataBound event.
<script type="text/javascript">
function sliderDataBound(sender) {
$get("message").innerHTML = "RadRotator control is data bound with " + sender.get_itemData().length + " items!";
}
</script>
