The documentation claims that this can be done with the set_width() method on the client side.

However, in order to call this method, you need a reference to the TileList.  According to the documentation, this is done via $telerik.findTileList(id, parent) where id is a string representation of the id and parent is the element containg the tilelist.

So, assuming the following document structure...

<body>
    <form id="form">
        <div id="tiles">
            <div id="centering">
                <telerirk RadTileList ID="NavTiles"></telerik:RadTileList>
            </div>
        </div>
    </form>
</body>


... what is the correct javascript to set the width of the TileList to 900px?  I can't make this work, because no matter what I pass to findTileList I always get null back.

Hi Duane Roelands,

Please have a look into the following code snippet to set the width of RadTileList through JavaScript.

ASPX:
<telerik:RadTileList ID="RadTileList1" runat="server" OnClientLoad="OnClientLoad1">
    <Groups>
        <telerik:TileGroup>
            <telerik:RadTextTile ID="RadTextTile1" runat="server" Text="Tile1">
            </telerik:RadTextTile>
        </telerik:TileGroup>
    </Groups>
</telerik:RadTileList>

JavaScript:
<script type="text/javascript">
    function OnClientLoad1(sender, args) {
        var tile = $find("<%=RadTextTile1.ClientID %>");
        tile.addCssClass("setwidth");
    }
</script>

CSS:
<style type="text/css">
    .setwidth
    {
        width: 900px !important;
    }
</style>

Thanks,
Princy.

The <% clientid %> solution is not tenable, because it inevitably produces the error message relating to the <% %> tags.

Please answer the original question as to accuracy of the online documentation regarding the JavaScript API.  Specifically, code samples that demonstrate how to use $telerik.findTileList(id, parent) and set_width().

Thank you.

Hi Duane Roelands,

The custom dimensions for the tiles are not supported in RadTileList. One suggestion is that you can override the CSS classes for the width of the element that holds the RadTiles. Please have a look into this forum thread.

Thanks,
Princy.

Okay, I'm going to try asking my question again, because I feel like you're not answering the question I am asking...

1. Your product documentation says that the width of the TileList control can be modified through client side code.
2. The documentation is here: http://www.telerik.com/help/aspnet-ajax/tilelist-client-side-tilelist-api.html
3. Please note at the bottom of the page, there is a method called set_width().
4. The documentation says that this method can be used to adjust the width of the TileList control.
5. The <% client Id %> solution is not sufficient for my needs.
6. Your documentation says it can be done through JavaScript.

Please provide a piece of sample code that uses the documentation page I have linked above the demonstrates using the set_width() method to change the size of the TileList control through Javscript.

Thank you.

                window.setTimeout(function () {

                }, 6000);

Review the comments in the javascript section. I hope they answer your question.
