c# - 样式自定义控件

Question

我做了自己的控制。一个继承自 DataGrid，另一个继承自 ContentControl。其中一个获取另一个，所以我尝试公开它们的属性，但由于我需要许多不同的控件，我想为我的控件(继承自 DataGrid 的控件)创建一个 Style 并从此设置属性控制到我的 ContentControl。我只是写了这样的代码，但它不起作用。任何人都知道我做错了什么？

<Style x:Key="CustomDataGridStyle"
       TargetType="{x:Type controls:CustomDataGrid}">
    <Setter Property="CurrentRow"
            Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type controls:DataGridContainer}}, Path=SelectedItem, Mode=TwoWay}" />
    <Setter Property="CaptionVisibility"
            Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type controls:DataGridContainer}}, Path=CaptionVisibility, Mode=TwoWay}" />
    <Setter Property="CaptionText"
            Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type controls:DataGridContainer}}, Path=CaptionText, Mode=TwoWay}" />
    <Setter Property="RowValidationErrorTemplate"
            Value="{StaticResource BasicRowValidationErrorTemplate}" />
    <Setter Property="CurrentView"
            Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type controls:DataGridContainer}}, Path=CurrentView, Mode=OneWayToSource}" />
    <Setter Property="CurrentColumnHeaderText"
            Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type controls:DataGridContainer}}, Path=CurrentColumnHeader, Mode=OneWayToSource}" />
    <Setter Property="SelectedCellText"
            Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type controls:DataGridContainer}}, Path=SelectedText, Mode=OneWayToSource}" />
    <Setter Property="IsDataGridFocused"
            Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type controls:DataGridContainer}}, Path=HasFocus, Mode=OneWayToSource}" />
</Style>

我已经这样定义了我的控件

<controls:CustomDataGrid x:Key="DataGridOne" AutoGenerateColumns="True" x:Shared="False" ItemsSource="{Binding UpdateSourceTrigger=PropertyChanged}" />

还有一个

<controls:DataGridContainer Content="{StaticResource DataGridOne}" DataContext="{Binding Products}" 
                                            x:Name="dataGridOne" SelectedItem="{Binding RelativeSource={RelativeSource FindAncestor, 
                                        AncestorType={x:Type UserControl}},
                                        Path=DataContext.SelectedItem, Mode=TwoWay}" CaptionVisibility="Collapsed"/>

您的样式设置了 x:Key 属性。这意味着默认情况下它不会应用于该类型的所有控件。您应该删除 Key 属性以使样式成为默认样式并应用于所有 CustomDataGrid 控件，或者在 CustomDataGrid 定义中引用样式，如下所示:

<Window>
  <Window.Resources>
    <Style x:Key="CustomDataGridStyle" TargetType="{x:Type controls:CustomDataGrid}">
     ...
    </Style>
  </Window.Resources>

 <controls:CustomDataGrid ... Style="{StaticResource CustomDataGridStyle}" ... />
</Window>
