# Templates

## Content



One of the main advantages to using a Silverlight 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 Silverlight applications, you can provide your own UI for data managed by **Expander for 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.

Accessing Templates

You can access templates in Microsoft Expression Blend by selecting the [C1Expander](/componentone/api/wpf/online-extended/dotnet-framework-api/C1.WPF.Extended.4.6.2/C1.WPF.Extended.C1Expander.html) control and, in the menu, selecting **Edit Template**. Select **Edit a Copy** to create an editable copy of the current template or select **Create Empty** to create a new blank template.

> **Note**: If you create a new template through the menu, the template will automatically be linked to that template's property. If you manually create a template in XAML you will have to link the appropriate template property to the template you've created.

Note that you can use the [Template](http://msdn2.microsoft.com/en-us/library/ms592524) property to customize the template.

**Additional Templates**

In addition templates, the **C1Expander** control includes a few additional templates. These additional templates can also be accessed in Microsoft Expression Blend – in Blend select the **C1Expander** control and, in the menu, select **Edit Additional Templates**. Choose a template, and select **Create Empty.**
