OnLoad

The load event occurs when the RadCheckBoxList client-side object is instantiated on the page.

The event handler receives two parameters:

1. The instance of the loaded RadCheckBoxList control.

2. An empty event args.

This event comes handy in scenarios when the user wants to operate with the control's client-side API and events at the earliest available stage.

Example 1: Handling RadCheckBoxList OnClientLoad event.

ASP.NET

<script type="text/javascript">
	function clientLoad(sender, args) {
		alert('RadCheckBoxList Object Loaded');
	}
</script>

<telerik:RadCheckBoxList runat="server" ID="RadCheckBoxList1">
	<ClientEvents OnLoad="OnLoad" />
	<Items>
		<telerik:ButtonListItem Text="English" Selected="true" />
		<telerik:ButtonListItem Text="German" />
		<telerik:ButtonListItem Text="French" />
	</Items>
</telerik:RadCheckBoxList>
