Problem of theme

[yjh]

If I set ApplicationTheme to Vista as below:

        public Page()
        {
            StyleManager.ApplicationTheme = ThemeManager.FromName("Vista");

            InitializeComponent();
        }

and set RadPanelBar as below:

        private void UserControl_Loaded(object sender, RoutedEventArgs e)
        {
            StyleManager.SetTheme(RadPanelBar1, ThemeManager.FromName("Office_Black"));

             RadPanelBar1.Items.Add(new RadPanelBarItem() { Header = "Test" });
        }

RadPanelBar 's theme is still Vista.But if I set

StyleManager.ApplicationTheme = ThemeManager.FromName("Summer");

and set

StyleManager.SetTheme(RadPanelBar1, ThemeManager.FromName("Vista");

RadPanelBar 's theme is Vista.

Why the first fails ?

Problem had been solved.

There is three method to get a theme:

1. ThemeManager.FromName("Office_Black");
2. new Office_BlackTheme();
3. new Theme(new Uri("/Telerik.Windows.Themes.Vista;component/Themes/generic.xaml", UriKind.Relative)));

Only No.3 can work in my program.

            StyleManager.SetTheme(RadPanelBar1, new Theme(
                new Uri("/Telerik.Windows.Themes.Office_Black;component/Themes/generic.xaml", UriKind.Relative)));

So, please use No.3 method as possible. It seems that only No.3 method support custom theme.

Why there is no official people say something ?

Hello yjh,

The proplem is that you wrote StyleManager.ApplicationTheme = ThemeManager.FromName("Vista");  in the page constructor , but you have to write in the Application constructor.
