Apply Themes

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.

Create a Quick start application and add the following .dll files to your application.
- C1.WPF.Theming
- C1.WPF.Theming.WhistlerBlue

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

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

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

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

            return _myTheme;
        }
    }
}

Add the following code in the loaded event to apply ComponentOne theme to the GanttView control.

C1Theme.ApplyTheme(gv, MyThemes.MyTheme)

//Apply C1 theme to GanttView
