OnClientItemChecked
The OnClientItemChecked client-side event occurs immediately after a particular item is being checked.
The event handler receives two parameters:
The instance of the combobox firing the event.
An eventArgs parameter containing the following method:
get_item returns the item that has just been checked.
get_domEvent() returns the DOM event object.
Use this event to respond to the newly checked item:
<script language="javascript" type="text/javascript">
function OnClientItemChecked(sender, eventArgs) {
var item = eventArgs.get_item();
sender.set_text("You checked " + item.get_text());
}
</script>
