I am using the latest build (13.2.590.0) and extracted just the RibbonSamples demo code from the larger SampleApplication-CSharp.VS2010 project. Everything builds and runs correctly, except that I cannot change the themes:
1. Using the ribbon buttons has no effect
2. Calling ThemeManager.SetTheme(this, ThemeNames.MetroDark.ToString()) in the constructor of MainRibbon() doesn't have any effect
3. Calling ThemeManager.CurrentTheme = ThemeNames.MetroDark.ToString() in the constructor of MainRibbon() doesn't have any effect
4. Using 2. or 3. followed by a call to ThemeManager.ApplyTheme(this.GetRootContainer(), ThemeName.MetroDark.ToString()) also doesn't show any effects.
When I click on the ribbon button on the SDK sample application the theme of the entire app updates correctly.
What am I missing?
