選択時にSilverlightデータグリッドセル内のテキストを太字にする

Question

XAMLを使用してSilverlight 4で太字の太字のテキストを選択しようとしています。私はDataGridCellテンプレートを変更しようとしましたが、選択範囲の背景色を変更するだけで、フォントの太さについては何も見つかりませんでした。

これは私がやったことで、私の作品：

<UserControl.Resources> 
     <Style x:Key="DataGridCellStyle1" TargetType="sdk:DataGridCell"> 
      <Setter Property="Background" Value="Transparent"/> 
      <Setter Property="HorizontalContentAlignment" Value="Stretch"/> 
      <Setter Property="VerticalContentAlignment" Value="Stretch"/> 
      <Setter Property="IsTabStop" Value="False"/> 
      <Setter Property="Template"> 
       <Setter.Value> 
        <ControlTemplate TargetType="sdk:DataGridCell"> 
         <Grid x:Name="Root" Background="{TemplateBinding Background}"> 
          <Grid.ColumnDefinitions> 
           <ColumnDefinition/> 
           <ColumnDefinition Width="Auto"/> 
          </Grid.ColumnDefinitions> 
          <VisualStateManager.VisualStateGroups> 
           <VisualStateGroup x:Name="CurrentStates"> 
            <VisualState x:Name="Regular"/> 
            <VisualState x:Name="Current"> 
             <Storyboard> 
              <DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="FocusVisual"/> 
              <ObjectAnimationUsingKeyFrames Storyboard.TargetName="contentPresenter" 
                      Storyboard.TargetProperty="(Content).FontWeight" 
                      Duration="0"> 
               <DiscreteObjectKeyFrame KeyTime="0" 
                     Value="Bold" /> 
              </ObjectAnimationUsingKeyFrames> 
             </Storyboard> 
            </VisualState> 
           </VisualStateGroup> 
           <VisualStateGroup x:Name="ValidationStates"> 
            <VisualState x:Name="Valid"/> 
            <VisualState x:Name="Invalid"> 
             <Storyboard> 
              <DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="InvalidVisualElement"/> 
              <ColorAnimation Duration="0" To="#FFFFFFFF" Storyboard.TargetProperty="(Fill).Color" Storyboard.TargetName="FocusVisual"/> 
             </Storyboard> 
            </VisualState> 
           </VisualStateGroup> 
          </VisualStateManager.VisualStateGroups> 
          <Rectangle x:Name="FocusVisual" Fill="#66FFFFFF" HorizontalAlignment="Stretch" IsHitTestVisible="false" Opacity="0" Stroke="Blue" StrokeThickness="3" VerticalAlignment="Stretch"/> 
          <ContentPresenter x:Name="contentPresenter" 
               Margin="0"            
               FlowDirection="RightToLeft" 
               ContentTemplate="{TemplateBinding ContentTemplate}" 
               Content="{TemplateBinding Content}" 
               HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
               VerticalAlignment="{TemplateBinding VerticalContentAlignment}"> 
          </ContentPresenter> 
           <Rectangle x:Name="InvalidVisualElement" HorizontalAlignment="Stretch" IsHitTestVisible="False" Opacity="0" Stroke="#FFDC000C" StrokeThickness="1" VerticalAlignment="Stretch"/> 
          <Rectangle x:Name="RightGridLine" Grid.Column="1" VerticalAlignment="Stretch" Width="1"/> 
         </Grid> 
        </ControlTemplate> 
       </Setter.Value> 
      </Setter> 
     </Style> 
    </UserControl.Resources> 

    <Grid x:Name="LayoutRoot" Background="White">   
     <sdk:DataGrid AutoGenerateColumns="False" 
         Height="154" 
         HorizontalAlignment="Left" 
         Margin="38,41,0,0" 
         Name="dataGrid1" 
         VerticalAlignment="Top" 
         Width="182" CellStyle="{StaticResource DataGridCellStyle1}" > 
      <sdk:DataGrid.Columns> 
       <sdk:DataGridTextColumn Binding="{Binding Key}" /> 
       <sdk:DataGridTextColumn Binding="{Binding Value}" /> 
      </sdk:DataGrid.Columns> 
     </sdk:DataGrid>   
    </Grid> 

MainPage.cs

IDictionary<string, object> test = new Dictionary<string, object>(); 
    test.Add(new KeyValuePair<string, object>("Name", "A")); 
    test.Add(new KeyValuePair<string, object>("Height", 2)); 

    this.dataGrid1.ItemsSource = test; 

における結合コードセルスタイルでこのコードを見て：

<ObjectAnimationUsingKeyFrames Storyboard.TargetName="contentPresenter" 
           Storyboard.TargetProperty="(Content).FontWeight" 
           Duration="0"> 
    <DiscreteObjectKeyFrame KeyTime="0" 
          Value="Bold" /> 
</ObjectAnimationUsingKeyFrames>
