    3. select Save to save the changes.

Styles in toolbar

You can now customize the toolbar in Unified Service Desk using the custom styles field in the Toolbar configuration window. The Custom Styles field supports Extensible Application Markup Language (XAML) that defines ResourceDictionary of Style and Brush resources.

The resources in the dictionary refers to other resources that are available on Unified Service Desk client application. Loading and parsing the XAML string is performed at runtime to create ResourceDictionary and merge the resources of the toolbar control with the ResourceDictionary. In addition, the ResourceDictionary can have styles for button types inside a toolbar. Using the styles, you can customize the toolbars and buttons.

Sample 1: The sample XAML that defines ResourceDictionary of Style and Brush resources demonstrates customizing the About Tool bar.

Note

You can find this sample XAML styles in Unified Service Desk - Unified Interface sample package.
