OnClientLoad

Updated on Aug 24, 2026

The OnClientLoad event is raised when the RadTileList object is initialized. It can notify the developer that the control isavailable (e.g. to store a reference to its client-side object for later use). For example, event handlers can be attached dynamically through the Client-side API of the RadTileList.

The event handler receives two arguments:

1. the RadTileList object that fired the event

2. an empty event arguments object

The following example shows how to set the SelectionMode of a RadTileList in its OnClientLoad event.

JavaScript

<telerik:RadTileList RenderMode="Lightweight" runat="server" ID="RadTileList1" OnClientLoad="OnClientLoad" AutoPostBack="true">
	<Groups>
		<telerik:TileGroup>
			<telerik:RadTextTile Name="Sample Text Tile" Text="Lorem ipsum dolor sit amet" Title-Text="Sample"></telerik:RadTextTile>
		</telerik:TileGroup>
	</Groups>
</telerik:RadTileList>

<telerik:RadCodeBlock runat="server" ID="RadCodeBlock1">
	<script type="text/javascript">
		function OnClientLoad(sender, args) {
			var tileList = $find("<%= RadTileList1.ClientID %>");

			tileList.set_selectionMode(Telerik.Web.UI.TileList.TileListSelectionMode.Single);
			//equivalent to tileList.set_selectionMode(2);
		
			//tileList.set_selectionMode(Telerik.Web.UI.TileList.TileListSelectionMode.None);
			//equivalent to tileList.set_selectionMode(1); 
		
			//tileList.set_selectionMode(Telerik.Web.UI.TileList.TileListSelectionMode.Multiple);
			//equivalent to tileList.set_selectionMode(4);

			alert(String.format("Selection Mode set to: Single, ({0})", tileList.get_selectionMode()));
		}
	</script>
</telerik:RadCodeBlock>

The code snippet below demonstrates how an event handler can be attached in the OnClientLoad event of the RadTileList.

JavaScript

		<telerik:RadTileList RenderMode="Lightweight" runat="server" ID="RadTileList1" OnClientLoad="OnClientLoad" AutoPostBack="false">
			<Groups>
				<telerik:TileGroup>
					<telerik:RadTextTile Name="Sample Text Tile" Text="Lorem ipsum dolor sit amet" Title-Text="Sample"></telerik:RadTextTile>
				</telerik:TileGroup>
			</Groups>
		</telerik:RadTileList>
	
		<script type="text/javascript">
			function OnClientLoad(tileList, args) {
				tileList.add_tileClicked(OnTileClickHandler);
			}
	
			function OnTileClickHandler() {
				alert('A Tile is clicked.');
			}
		</script>
