You can save the application’s theme and palette to the configuration file and restore them on the next application run.
To save an applied theme and palette, use the static ApplicationThemeHelper.SaveApplicationThemeName method to save the theme name specified in the static ApplicationThemeHelper.ApplicationThemeName property:
private void Application_Exit(object sender, StartupEventArgs e) {
ApplicationThemeHelper.SaveApplicationThemeName();
}
Private Sub Application_Exit(ByVal sender As Object, ByVal e As StartupEventArgs)
ApplicationThemeHelper.SaveApplicationThemeName()
End Sub
Call the static ApplicationThemeHelper.UpdateApplicationThemeName method to retrieve the theme name from the configuration file and apply it to your application:
private void Application_Startup(object sender, ExitEventArgs e) {
ApplicationThemeHelper.UpdateApplicationThemeName();
}
Private Sub Application_Startup(ByVal sender As Object, ByVal e As StartupEventArgs)
ApplicationThemeHelper.UpdateApplicationThemeName()
End Sub
