Render Modes

A RadTile has different render modes that can change certain aspects of the control rendering or provide certain advantages. They are exposed via the RenderMode property that has four possible values - Classic, Lightweight, Mobile and Auto.

The markup a RadTile uses is as lightweight and as semantic as possible. The change that may occur is to enable its elastic design.

The possible options for the RenderMode property are:

  • Classic—this mode is the rendering that has been used before. It remains without changes and it is the default value of the property.

  • Lightweight—this mode emphasizes on semantic HTML and CSS3. It reduces the amount of markup the control renders and makes it easier to customize. This also reduces the number of image sprites required by the control. All of this decreases the overall size and complexity of each skin, including custom ones. The control is elastic and font-icons are used instead of image sprites for the selection indicator and predefined badges.

  • Mobile—this mode is currently not supported. If you set it, the mode will fall back automatically to Lightweight.

  • Auto—this mode makes each control choose the appropriate rendering mode according to the used browser—Classic or Lightweight.

important

RadTile, as well as the other Telerik controls that utilize render modes, supports only one type of render mode per page. This includes mode being set for a standalone instance(s), and a programmatically created instance(s). All such controls must have the same RenderMode on a given page.This also includes instances from user controls and master pages.

note

RadTileList uses RadTile controls internally, so all their instances must have the same render mode. Tiles that are children of a TileList will inherit the RenderMode of the TileList.

Setting Render Mode

There are two ways to configure the rendering mode of the controls:

  • The RenderMode property in the markup or in the code-behind that can be used for a particular instance:

    ASP.NET

    <telerik:RadTextTile ID="RadTextTile1" runat="server" RenderMode="Lightweight">
    </telerik:RadTextTile>
    

    C#

    RadTextTile1.RenderMode = Telerik.Web.UI.RenderMode.Lightweight;
    

    VB

    RadTextTile1.RenderMode = Telerik.Web.UI.RenderMode.Lightweight
    
  • A global setting in the web.config file that will affect the entire application, unless a concrete value is specified for a given control instance:

    XML

    <appSettings>
        <add key="Telerik.Web.UI.BaseTile.RenderMode" value="Lightweight" />
    </appSettings>
    
    tip

    The key above will affect all RadTile instances. If you want to target specific tile types, use their name in the key instead of BaseTile: TextTile, IconTile, ImageTile, ImageAndTextTile, ContentTemplateTile, LiveTile.
