Applying a Modified Theme to a WPF Application

• Aug 03, 2020

Note

The WPF Theme Editor does not support the DevExpress WPF Controls 18.2 or later. Use the WPF Theme Designer tool instead.

This tutorial demonstrates how to apply a theme modified via the Theme Editor to a WPF application. Use the theme you have created in the previous lesson.

To apply this theme to an application, follow the steps below.

1. Run Visual Studio and open a WPF solution to which you wish to apply the theme.

2. Add a reference to the theme assembly in this solution. To do this, right-click References in the Solution Explorer and select Add Reference. In the Browse tab, locate the following assembly:

   C:\Program Files (x86)\DevExpress 18.2\Components\Sources\DevExpress.Xpf.Themes\DevExpress.Xpf.Themes.NewTheme\Bin\DevExpress.Xpf.Themes.NewTheme.v18.1.dll

   

3. Add the following code to the MainWindow constructor.

   C#

   using DevExpress.Xpf.Core;
   //...
   public partial class MainWindow : Window {
       public MainWindow() {
           Theme theme = new Theme("NewTheme", "DevExpress.Xpf.Themes.NewTheme.v18.1");
           theme.AssemblyName = "DevExpress.Xpf.Themes.NewTheme.v18.1";
           Theme.RegisterTheme(theme);
           ThemeManager.SetTheme(this, theme);
           InitializeComponent();
       }
   }
   

   VB.NET

   Imports DevExpress.Xpf.Core
   '...
   Partial Public Class MainWindow
           Inherits Window
           Public Sub New()
                   Dim theme As New Theme("NewTheme", "DevExpress.Xpf.Themes.NewTheme.v18.1")
                   theme.AssemblyName = "DevExpress.Xpf.Themes.NewTheme.v18.1"
                   Theme.RegisterTheme(theme)
                   ThemeManager.SetTheme(Me, theme)
                   InitializeComponent()
           End Sub
   End Class
   

4. Run the application to view the result.
