Copy[C#] Setting a theme for the entire application
ThemeResolutionService.ApplicationThemeName = "Office2007Black";
Copy[VB.NET] Setting a theme for the entire application
ThemeResolutionService.ApplicationThemeName = "Office2007Black"

You still have to drop the theme component on the form (e.g. Office2007Black in the code samples above). |
All your controls will use that specified theme which has precedence over the theme set locally to the control using ThemeName property.
