WPF DataGrid的風格背後

Question

我有我的WPF應用程序DataGrid的一個XAML代碼風格，我現在寫的是從DataGrid中繼承的自定義控制的想在代碼應用以下樣式背後：

<Style TargetType="DataGrid"> 

    <!-- Make the border and grid lines a little less imposing --> 
    <Setter Property="BorderBrush" Value="#DDDDDD" /> 
    <Setter Property="HorizontalGridLinesBrush" Value="#DDDDDD" /> 
    <Setter Property="VerticalGridLinesBrush" Value="#DDDDDD" /> 

    <Setter Property="RowStyle"> 
     <Setter.Value> 
      <Style TargetType="DataGridRow"> 
       <Style.Triggers> 
        <!-- Highlight a grid row as the mouse passes over --> 
        <Trigger Property="IsMouseOver" Value="True"> 
         <Setter Property="Background" Value="Lavender" /> 
        </Trigger> 
       </Style.Triggers> 
      </Style> 
     </Setter.Value> 
    </Setter> 
    <Setter Property="CellStyle"> 
     <Setter.Value> 
      <Style TargetType="DataGridCell"> 
       <Style.Triggers> 
        <!-- Highlight selected rows --> 
        <Trigger Property="IsSelected" Value="True"> 
         <Setter Property="Background" Value="Lavender" /> 
         <Setter Property="BorderBrush" Value="Lavender" /> 
         <Setter Property="Foreground" Value="Black" /> 
        </Trigger> 
        <!--StartsEditingOnMouseOver--> 
        <!--<Trigger Property="IsMouseOver" Value="True"> 
         <Setter Property="IsEditing" Value="True" /> 
        </Trigger>--> 
       </Style.Triggers> 

       <EventSetter Event="PreviewMouseLeftButtonDown" Handler="DataGridCell_PreviewMouseLeftButtonDown" /> 
       <EventSetter Event="PreviewTextInput" Handler="DataGridCell_PreviewTextInput" /> 

       <!-- Add some padding around the contents of a cell --> 
       <Setter Property="Padding" Value="4,3,4,3" /> 
       <Setter Property="Template"> 
        <Setter.Value> 
         <ControlTemplate TargetType="DataGridCell"> 
          <Border Padding="{TemplateBinding Padding}" 
          Background="{TemplateBinding Background}"> 
           <ContentPresenter /> 
          </Border> 
         </ControlTemplate> 
        </Setter.Value> 
       </Setter> 
      </Style> 
     </Setter.Value> 
    </Setter> 
</Style> 

我有什麼迄今下面的代碼：

static DionysusDataGrid() 
{ 

    BorderBrushProperty.OverrideMetadata(typeof(DionysusDataGrid), new FrameworkPropertyMetadata(ColorConverter.ConvertFromString("#FFDDDDDD") as Color?)); 
    HorizontalGridLinesBrushProperty.OverrideMetadata(typeof(DionysusDataGrid), new FrameworkPropertyMetadata(ColorConverter.ConvertFromString("#FFDDDDDD") as Color?)); 
    VerticalGridLinesBrushProperty.OverrideMetadata(typeof(DionysusDataGrid), new FrameworkPropertyMetadata(ColorConverter.ConvertFromString("#FFDDDDDD") as Color?)); 

} 

但我不知道如何做同樣的「RowStyle」屬性，它也有一個風格本身。並且在設置BorderBrushProperty時我也遇到以下錯誤：

Default value type does not match type of property 'BorderBrush'." 

任何人都可以幫我解決嗎？

感謝名單

UPDATE：

我的代碼更新到下面的解析錯誤：

static DionysusDataGrid() 
{ 

    BrushConverter converter = new BrushConverter(); 

    BorderBrushProperty.OverrideMetadata(typeof(DionysusDataGrid), new FrameworkPropertyMetadata((System.Windows.Media.Brush)converter.ConvertFromString("#FFDDDDDD"))); 
    HorizontalGridLinesBrushProperty.OverrideMetadata(typeof(DionysusDataGrid), new FrameworkPropertyMetadata((System.Windows.Media.Brush)converter.ConvertFromString("#FFDDDDDD"))); 
    VerticalGridLinesBrushProperty.OverrideMetadata(typeof(DionysusDataGrid), new FrameworkPropertyMetadata((System.Windows.Media.Brush)converter.ConvertFromString("#FFDDDDDD"))); 

} 

Answer 1

要使風格在後面的代碼，一些一般的規則：

您在XAML中輸入的任何內容在舊版C＃中都有相應的內容：

<Style ...>只是System.Windows.Style。 Setter，Trigger也是如此，您可以將其命名。

唯一的疑難雜症來自ContentProperty屬性，它是默認屬性分配，例如，當你這樣做：

<TextBlock>My text here!</TextBlock> 

它設置TextBlock.Text屬性"My text here!"，因爲TextBlock類標有屬性[ContentProperty("Text")]

最後，你需要從最嵌套的元素開始，當你從C＃編譯：

<Style TargetType="DataGrid"> 
    <Setter Property="BorderBrush" Value="#DDDDDD" /> 
</Style> 

變爲：

var brushConverter = new BrushConverter(); 

var bbSetter = new Setter(
    DataGrid.BorderBrushProperty, 
    brushConverter.ConvertFromString("#FFDDDDDD")); 

var style = new Style(typeof(DataGrid));  
style.Setters.Add(bbSetter); 

從這個你應該能夠對任何XAML轉換爲C＃，
要注意，雖然，你不能映射任何C＃來XAML，例如，你可以是非常有用的在XAML中製作動態故事板，但你可以在C＃中使用。
