This article demonstrates how the OnClientTileCreating event can be used to cancel tile creation upon custom logic.

The OnClientTileCreating event is raised before the tile is initialized by the TileList.

The event handler receives two arguments:

  1. the RadTileList object that fired the event

  2. an event arguments object that exposes the following methods

OnClientTileCreating event arguments object

Name Return type Arguments Description
get_cancel() bool Gets a value that indicates whether the tile creation is canceled.
get_dataItem() object Gets the data source object.
get_tileData() object Gets the data that will be generated as tile by the TileList.
set_cancel() bool Sets whether the tile creation will be canceled (if true is passed).
set_tileData() object Sets an object that will be created as tile by the TileList.

Example 1 demonstrates how to use the OnClientTileCreating event to cancel the tile creation upon some sample logic.

Example 1: Using OnClientTileCreating event.

<telerik:RadClientDataSource runat="server" ID="RadClientDataSource1" AllowPaging="true" PageSize="10">
        <WebServiceDataSourceSettings BaseUrl="">
            <Select Url="products" DataType="JSONP" />

<telerik:RadTileList RenderMode="Lightweight" runat="server" ID="RadTileList1" Height="400"
    ClientDataSourceID="RadClientDataSource1" OnClientTileCreating="OnClientTileCreating">
        <CommonTileBinding TileType="RadTextTile" DataNameField="ProductID" DataTitleTextField="UnitsInStock" />
        <TextTileBinding DataTextField="ProductName" />

<script type="text/javascript">
    function OnClientTileCreating(sender, args) {
        var dataItem = args.get_dataItem(),
            unitsInStock = dataItem.UnitsInStock,
            isUnavailable = unitsInStock == 0;
