WPF Accordion Themes

Accordion for WPF incorporates several themes that allow you to customize the appearance of your grid. When you first add a C1Accordion control to the page, it appears similar to the following image:

This is the control's default appearance. You can change this appearance by using one of the built-in themes or by creating your own custom theme. All of the built-in themes are based on WPF Toolkit themes. The built-in themes are described and pictured below; note that in the images below, a row has been selected to show selected styles:

Theme Name	Theme Preview
C1Blue
C1ThemeBureauBlack
C1ThemeExpressionDark
C1ThemeExpressionLight
C1ThemeOffice2007Blue
C1ThemeOffice2007Black
C1ThemeOffice2007Silver
C1ThemeOffice2010Blue
C1ThemeOffice2010Black
C1ThemeOffice2010Silver
C1ThemeShinyBlue
C1ThemeWhistlerBlue

To set an element's theme, use the ApplyTheme method. First add a reference to the theme assembly to your project, and then set the theme in code, like this:

Visual Basic	Copy Code
Private Sub Window_Loaded(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded Dim theme As New C1ThemeExpressionDark ' Using ApplyTheme C1Theme.ApplyTheme(LayoutRoot, theme)

Visual Basic

Copy Code

Private Sub Window_Loaded(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded
   Dim theme As New C1ThemeExpressionDark
   ' Using ApplyTheme
   C1Theme.ApplyTheme(LayoutRoot, theme)

C#	Copy Code
private void Window_Loaded(object sender, RoutedEventArgs e) { C1ThemeExpressionDark theme = new C1ThemeExpressionDark(); //Using ApplyTheme C1Theme.ApplyTheme(LayoutRoot, theme); }

To apply a theme to the entire application, use the System.Windows.ResourceDictionary.MergedDictionaries property. First add a reference to the theme assembly to your project, and then set the theme in code, like this:

Visual Basic	Copy Code
Private Sub Window_Loaded(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded Dim theme As New C1ThemeExpressionDark ' Using Merged Dictionaries Application.Current.Resources.MergedDictionaries.Add(C1Theme.GetCurrentThemeResources(theme)) End Sub

Visual Basic

Copy Code

Private Sub Window_Loaded(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded
   Dim theme As New C1ThemeExpressionDark
   ' Using Merged Dictionaries
Application.Current.Resources.MergedDictionaries.Add(C1Theme.GetCurrentThemeResources(theme))
End Sub

C#	Copy Code
private void Window_Loaded(object sender, RoutedEventArgs e) { C1ThemeExpressionDark theme = new C1ThemeExpressionDark(); //Using Merged Dictionaries Application.Current.Resources.MergedDictionaries.Add(C1Theme.GetCurrentThemeResources(theme)); }

Copy Code

private void Window_Loaded(object sender, RoutedEventArgs e)
   {
      C1ThemeExpressionDark theme = new C1ThemeExpressionDark();
      //Using Merged Dictionaries        Application.Current.Resources.MergedDictionaries.Add(C1Theme.GetCurrentThemeResources(theme));
   }

Note that this method works only when you apply a theme for the first time. If you want to switch to another ComponentOne theme, first remove the previous theme from Application.Current.Resources.MergedDictiona
