Change theme(style??) programmatically

[Aeroth]

Hi Telerik Team,
How can I change RadWinow theme (style??) programmatically?
I've created a new class(not xaml file) that inherits from RadWindow and I'd like to change foreground and background of the Header, and the style of Minimize, Maximize, Close (X) buttons when my custom window instantiated.
As your demo example, the Header foreground is white and background is blue.

Where can I get all default themes list? 

Please help me out , thanks!

Regards,
Aeroth Lin

Hi Aeroth,

RadControls ship with nine ready-to-use themes. You can use them to customize the appearance of the RadWindow control. The one you are referring to and the one that is used thoughout our online demos is the Metro theme. Other themes include: Office Black, Office Blue, Office SIlver, Vista, Summer, Windows7, Transparent, Expression Dark. You can check all of them in the theming example of RadWidnow.

So to force your instance of RadWindow to have the look and feel of any of the themes, you should apply a theme to it. In XAML:

<telerik:RadWindow telerik:StyleManager.Theme="Metro" />

In code-behind:

StyleManager.SetTheme(myWindow, new MetroTheme());

Or set an application theme:

StyleManager.ApplicationTheme = new MetroTheme();

If you choose to have one of the themes , but wish to apply additional changes to the look & feel, you should make customizations upon the XAML for that particular theme.

I hope this helps.

Kind regards,

Hi Dani,
Thanks for the reply. I added a reference to Telerik.Windows.Themes.Office_Blue.dll and set the theme to Office_BlueTheme but it does not work. Did I miss anything?

StyleManager.SetTheme(this, new Office_BlueTheme());

Hello Aeroth,

You have to make sure that you add this line before InitializeComponent(). Attached is a working sample. It contains a RadWindow both as a separate UserControl and as an element inside the MainPage UserControl.

I hope this helps.

Hi Dani,

The attached sample works. Unfortunately mine does not =.=, I don't know where's going wrong.
Please check this for me:

MyRadWindow.xaml

    <Grid x:Name="LayoutRoot">

    </Grid>
</navigation:RadWindow>

MyRadWindow.xaml.cs

public partial class MyRadWindow : RadWindow
    {
        #region Constructor
        public MyRadWindow()
        {
            StyleManager.SetTheme(this, new Office_BlueTheme());
            InitializeComponent();

            Grid grid = new Grid();
            grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(1, GridUnitType.Star) });
            grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(10, GridUnitType.Star) });
            TextBox content = new TextBox()
            {
                IsReadOnly = true,
                Background = new SolidColorBrush(Colors.White),
                TextWrapping = TextWrapping.Wrap,
                FontSize = 13F
            };
            Grid.SetRow(content, 0);
            Grid.SetColumn(content, 0);
            grid.Children.Add(content);
            base.Content = grid;
            base.WindowStartupLocation = Telerik.Windows.Controls.WindowStartupLocation.CenterScreen;
            base.Width = 500;
            base.Height = 100;
        }
        #endregion
    }
