Setting a Theme

The controls from our suite support different themes. You can see how to apply a theme different than the default one in the Setting a Theme help article.

Changing the theme using implicit styles will affect all controls that have styles defined in the merged resource dictionaries. This is applicable only for the controls in the scope in which the resources are merged.

To change the theme, you can follow the steps below:

  • Choose between the themes and add reference to the corresponding theme assembly (ex: Telerik.Windows.Themes.Windows8.dll). You can see the different themes applied in the Theming examples from our WPF Controls Examples application.

  • Merge the ResourceDictionaries with the namespace required for the controls that you are using from the theme assembly. For RadWatermarkTextBox, you will need to merge the following resources:

    • Telerik.Windows.Controls

Example 3 demonstrates how to merge the ResourceDictionaries so that they are applied globally for the entire application.

Example 3: Merge the ResourceDictionaries

                <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/System.Windows.xaml"/> 
                <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.xaml"/> 

Figure 3 shows RadWatermarkTextBox with the Windows8 theme applied.
