OnClientLoad
The OnClientLoad client-side event occurs after RadListBox has been fully initialized on the client-side.
The event handler receives one parameter:
- The listbox instance firing the event.
This event is helpful if you need to get the client-side instance of the listbox when it is embedded in other controls. Hook the OnClientLoad event and get the client-side instance of the listbox as demonstrated in the example below. This technique can be used to retrieve the RadListBox instance for use elsewhere.
JavaScript
var listbox;
function OnClientLoadHandler(sender) {
listbox = sender;
}
<telerik:RadListBox RenderMode="Lightweight" ID="RadListBox1" runat="server" OnClientLoad="OnClientLoadHandler" ... />
