The OnClientLoad client-side event occurs after the RadTreeMap has been fully initialized on the client-side.

The event handler receives one parameter:

• The instance of the RadTreeMap control firing the event.

Hook the OnClientLoad event and get the client-side instance of the RadTreeMap as demonstrated in the example below. This technique can be used to retrieve the RadTreeMap instance for use elsewhere.

JavaScript

<script type="text/javascript">
var treemap;
function OnClientLoad(sender) {
    treemap = sender;
}
</script>

<telerik:RadTreeMap RenderMode="Lightweight" runat="server" ID="TreeMap1" OnClientLoad="OnClientLoad">

    <telerik:TreeMapItem Text="Parent Item">
        <Items>
