One of the main advantages to using a WPF control is that controls are "lookless" with a fully customizable user interface. Just as you design your own user interface (UI), or look and feel, for WPF applications, you can provide your own UI for items managed by TileView for WPF and Silverlight. Extensible Application Markup Language (XAML, pronounced "Zammel"), an XML-based declarative language, offers a simple approach to designing your UI without having to write code.
You can access templates in Microsoft Expression Blend by selecting the C1TileView control and, in the menu, selecting Edit Template. Select Edit a Copy to create an editable copy of the current template or Create Empty to create a new blank template.
Once you create a new template, the template appears in the Objects and Timeline window. You can use the Template property to customize the template.
Note: If you create a new template through the menu, the template is automatically linked to that template's property. If you manually create a template in XAML you have to link the appropriate template property to the template you created.
In addition to the default template, the C1TileView control includes a few additional templates. These additional templates can also be accessed in Microsoft Expression Blend. In Blend, select the C1TileView control and, in the menu, select Edit Additional Templates. Choose a template, and select Create Empty.
