silverlight中动态切换主题样式

所先需要引用System.Windows.Controls.Theming命名空间

然后，微软的提供了一些主题，可供使用，根据自己的需要来引用这些类

Microsoft.Windows.Controls.Theming.BubbleCream

Microsoft.Windows.Controls.Theming.BureauBlack

Microsoft.Windows.Controls.Theming.BureauBlue

Microsoft.Windows.Controls.Theming.ExpressionDark

Microsoft.Windows.Controls.Theming.ExpressionLight

Microsoft.Windows.Controls.Theming.RainierOrange

Microsoft.Windows.Controls.Theming.RainierPurple

Microsoft.Windows.Controls.Theming.ShinyBlue

Microsoft.Windows.Controls.Theming.ShinyRed

Microsoft.Windows.Controls.Theming.TwilightBlue

Microsoft.Windows.Controls.Theming.WhistlerBlue

然后分几部

1.添加一个名为Controls.xaml的UserControl，代码清单如下

<UserControl x:Class=”DynamicStylingExample.Controls”
     xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation”
     xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml”
     xmlns:d=”http://schemas.microsoft.com/expression/blend/2008”
     xmlns:mc=”http://schemas.openxmlformats.org/markup-compatibility/2006
     xmlns:data=”clr-
namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data”
     xmlns:controls=”clr-
namespace:System.Windows.Controls;assembly=System.Windows.Controls”>
     <StackPanel x:Name=”ControlsRoot”>
          <StackPanel Orientation=”Horizontal” Margin=”0,10”>
               <Button Content=”Button Control” />
               <TextBox Margin=”10,0,0,0” Width=”200” 
Text=”Styled TextBox” />
          </StackPanel>
          <StackPanel Orientation=”Horizontal” Margin=”0,10”>
               <Slider Margin=”10,0,0,0” Maximum=”100” Minimum=”0” 
Value=”0” />
          </StackPanel>
          <data:DataGrid x:Name=”CustomFoodsGrid” Margin=”0,10” />
          <controls:Calendar Margin=”0,10” />
     </StackPanel>
</UserControl>

2.在MainPage.xaml文件中添加一个ComboBox，通过ComboBox来选择主题

<UserControl x:Class=”DynamicStylingExample.MainPage”
     xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation” 
     xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml”
     xmlns:dynamic=”clr-namespace:DynamicStylingExample”>
     <Grid x:Name=”LayoutRoot”>
          <StackPanel x:Name=”MainPanel”>
               <ComboBox x:Name=”ThemeList”>
                    <ComboBox.ItemTemplate>
                         <DataTemplate>
                              <TextBlock Text=”{Binding ThemeName}” />
                         </DataTemplate>
                    </ComboBox.ItemTemplate>
               </ComboBox>
               <dynamic:Controls x:Name=”Controls” />
          </StackPanel>
     </Grid>
</UserControl>

3.写一个类用来填充ComboBox

public class ThemeSelector
{
     public string ThemeName { get; set; }
     public ContentControl Theme { get; set; }
}

4.写一个返回主题样式集合的方法在MainPage类的构造函数中调用

private void LoadThemeList()
{
     List<ThemeSelector> themes = new List<ThemeSelector>();
     themes.Add(new ThemeSelector { ThemeName = “BubbleCreme”, 
Theme = new BubbleCremeTheme() });
     themes.Add(new ThemeSelector { ThemeName = “BureauBlack”, 
Theme = new BureauBlackTheme() });
     themes.Add(new ThemeSelector { ThemeName = “BureauBlue”, 
Theme = new BureauBlueTheme() });
     themes.Add(new ThemeSelector { ThemeName = “ExpressionDark”,
Theme = new ExpressionDarkTheme() });
     themes.Add(new ThemeSelector { ThemeName = “ExpressionLight”
Theme = new ExpressionLightTheme() });
     themes.Add(new ThemeSelector { ThemeName = “RainierOrange”, 
Theme = new RainierOrangeTheme() });
     themes.Add(new ThemeSelector { ThemeName = “RainierPurple”, 
Theme = new RainierPurpleTheme() });
     themes.Add(new ThemeSelector { ThemeName = “ShinyBlue”, 
Theme = new ShinyBlueTheme() });
     themes.Add(new ThemeSelector { ThemeName = “ShinyRed”, 
Theme = new ShinyRedTheme() });
     themes.Add(new ThemeSelector { ThemeName = “TwilightBlue”, 
Theme = new TwilightBlueTheme() });
     themes.Add(new ThemeSelector { ThemeName = “WhistlerBlue”, 
Theme = new WhistlerBlueTheme() });
     ThemeList.ItemsSource = themes;
}

5.最后在ComboxBox的SelectionChanged事件中写更改主题的代码

private void ThemeList_SelectionChanged(object sender,
SelectionChangedEventArgs e)
{
     ContentControl theme = ((sender as ComboBox).SelectedItem as
ThemeSelector).Theme;
     theme.Content = new Controls();
     MainPanel.Children.RemoveAt(1);
     MainPanel.Children.Add(theme);
}
