Property Value

If specified, the OnClientItemsRequesting client-side event handler is called when the KaxComboBox is about to be populated. Two parameters are passed to the handler:

• sender, the menu client object;
• eventArgs with three properties:
  • get_context(), an user object that will be passed to the web service.
  • set_cancel(), used to cancel the event.

This event can be cancelled.

<script type="text/javascript">
function onItemRequestingHandler(sender, eventArgs)
{
var context = eventArgs.get_context();
context["Parameter1"] = "Value";
}
</script>
