GanttView supports built-in ComponentOne themes available in C1.WPF.Theming library. You can apply any of the available C1 themes to the GanttView control and provide a customized and consistent appearance to the application. To understand how themes can be used effectively, see Theming.

The following image shows a GanttView with C1WhistlerBlue theme applied to it.

The following steps illustrate how to apply C1 themes to GanttView. This example uses the sample created in the Quick start.

1. Create a Quick start application and add the following .dll files to your application.
   • C1.WPF.Theming
   • C1.WPF.Theming.WhistlerBlue
2. Switch to the MainWindow.xaml.cs file and add the following import statements.
   • Visual Basic
   • C#

   • Visual Basic

   Imports C1.WPF.Theming
   Imports C1.WPF.Theming.WhistlerBlue
   

   • C#

   using C1.WPF.Theming;
   using C1.WPF.Theming.WhistlerBlue;
   

3. Create a class, MyTheme, to create an object of the C1Themes class.
   • Visual Basic
   • C#

   • Visual Basic

   Public Class MyThemes
       Private Shared _myTheme As C1Theme = Nothing
       Public Shared ReadOnly Property MyTheme() As C1Theme
           Get
               If _myTheme Is Nothing Then
                   _myTheme = New C1ThemeWhistlerBlue()
               End If
   
               Return _myTheme
           End Get
       End Property
   End Class
   

   • C#

   public class MyThemes
   {
       private static C1Theme _myTheme = null;
       public static C1Theme MyTheme
       {
           get
           {
               if (_myTheme == null)
               {
                   _myTheme = new C1ThemeWhistlerBlue();
               }
   
               return _myTheme;
           }
       }
   }
   

4. Add the following code in the loaded event to apply ComponentOne theme to the GanttView control.
   • Visual Basic
   • C#

   • Visual Basic

   'Apply C1 theme to GanttView
   C1Theme.ApplyTheme(gv, MyThemes.MyTheme)
   

   • C#

   //Apply C1 theme to GanttView 
   C1Theme.ApplyTheme(gv, MyThemes.MyTheme);
