Metro App Callisto框架擴展CustomDialog - 添加TitleBackground

Question

有誰知道如何從Callisto地鐵應用程序框架擴展CustomDialog控件，添加TitleBackground屬性？

實際上，我想爲Title出現的行着色Background。

Answer 1

想通了：

在CustomDialog.cs補充：

public Brush TitleBackground 
    { 
     get { return (Brush)GetValue(TitleBackgroundProperty); } 
     set { SetValue(TitleBackgroundProperty, value); } 
    } 

    public static readonly DependencyProperty TitleBackgroundProperty = 
     DependencyProperty.Register("TitleBackground", typeof(Brush), typeof(CustomDialog), null); 

然後在Generic.xaml，轉到CustomDialog風格和網格定義修改爲：

     <Grid.ColumnDefinitions> 
          <ColumnDefinition/> 
          <ColumnDefinition Width="Auto"/> 
          <ColumnDefinition/> 
         </Grid.ColumnDefinitions> 
         <Grid.RowDefinitions> 
          <RowDefinition Height="80"/> 
          <RowDefinition Height="*"/> 
         </Grid.RowDefinitions> 
         <Rectangle Grid.ColumnSpan="3" Grid.Row="0" Fill="{TemplateBinding TitleBackground}"/> 
         <Button Grid.Column="0" Grid.Row="0" x:Name="PART_BackButton" HorizontalAlignment="Right" VerticalAlignment="Top" Margin="0,24,0,0" Style="{StaticResource DialogBackButtonStyle}" Command="{TemplateBinding BackButtonCommand}" CommandParameter="{TemplateBinding BackButtonCommandParameter}" Visibility="{TemplateBinding BackButtonVisibility}"/> 
         <local:DynamicTextBlock Grid.Column="1" Grid.Row="0" Foreground="{TemplateBinding TitleForeground}" x:Name="PART_Title" Text="{TemplateBinding Title}" FontFamily="Segoe UI" FontSize="26.6667" FontWeight="Light" Margin="0,0,0,8" /> 
         <ContentPresenter Grid.Column="1" Grid.Row="1" Margin="0" x:Name="PART_Content" Foreground="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=Background, Converter={StaticResource ColorContrast}}" />
