ColorPicker for WPF includes over 20 predefined color palettes that match the themes used in Microsoft Office. For more information about palette choices, see Available ColorPicker Palettes. To change the color palette, you can set the Palette property.
To set the Palette property, complete the following steps:
1. Navigate to the Toolbox and double-click the Button icon to add the control to the project.
2. Resize and reposition the Button on the form.
3. Navigate to the Properties window and set the button’s Content property to "Change Palette".
4. Double-click the button to switch to Code view and create the Button_Click event handler.
5. Add code for the Button_Click event handler, so it appears like the following:
Private Sub Button1_Click(ByVal sender as Object, ByVal e as System.Windows.RoutedEventArgs)
' Set the color palette.
Me.C1ColorPicker.Palette = ColorPalette.GetColorPalette(Office2007ColorTheme.GrayScale)
End Sub
•C#
private void button1_Click(object sender, System.Windows.RoutedEventArgs e)
{
// Change color palette.
this.c1ColorPicker.Palette = ColorPalette.GetColorPalette(Office2007ColorTheme.GrayScale);
}
The C1ColorPicker's color palette will now change to grayscale when the button is clicked.
Run the application and observe:
