WPF MVVM Behaviors - Display Theme Selectors Based on BarItems and Hide Themes from List

DevExpress WPF Controls include the following behaviors that display a theme gallery in Bars and Ribbon controls:

• RibbonGalleryItemThemeSelectorBehavior
• BarSubItemThemeSelectorBehavior
• BarSplitItemThemeSelectorBehavior

This example displays these theme selectors in the Ribbon.

Hide Themes from Theme Selector

You can use the Theme.ShowInThemeSelector property to hide a theme/theme category from behaviors.

In this example, the Standard and Metropolis theme categories are hidden.

Persist Theme Selection between Application Runs

Use can save the application's theme to the configuration file and restore it on the next application run.

To save an applied theme, use the static ApplicationThemeHelper.SaveApplicationThemeName method to save the theme name specified in the static ApplicationThemeHelper.ApplicationThemeName property.
