Silverlight themes are a collection of image settings that define the look of a control or controls. The benefit of using themes is that you can apply the theme across several controls in the application, thus providing consistency without having to repeat styling tasks.
When C1DockControl is added to your project, it appears with the default theme, which looks similar to the following image:
But the C1DockControl can also be themed with one of the many included themes. Please see the Available Themes topic for a list of themes that can be applied.
You can add any of these themes to a C1DockControl by declaring it around the control in XAML markup. For more information about adding themes, see the Using Silverlight Themes.
