获取ItemsControl的子级?

问题描述

Hi i would like to add different style to my txtTitle using datatrigger. However i do not know how to get the child 

of my ChildrenList in my datatrigger. The child are all using the same name - txtTitle and txtSupportText.

  <DataTemplate DataType="{x:Type dm:QualityElementViewModel}">
      <StackPanel>
        <TextBox x:Name="txtTitle" Text="{Binding Path=Title,Mode=TwoWay,ValidatesOnDataErrors=True,UpdateSourceTrigger=PropertyChanged}"
             Background="Blue" FontWeight="Bold" Foreground="White" Style="{DynamicResource normalStyle}" />
        <TextBox x:Name="txtSupportText" Text="{Binding Path=SupportingText,Mode=TwoWay,ValidatesOnDataErrors=True,UpdateSourceTrigger=PropertyChanged}"
          Style="{StaticResource normalStyle}" AcceptsReturn="True" />
        <ItemsControl ItemsSource="{Binding ChildrenList}"/>
      </StackPanel>

      
      <DataTemplate.Triggers>
        <DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type Window}}, Path=IsInEditMode}" Value="True">
          <Setter TargetName="txtSupportText" Property="Style" Value="{StaticResource editingStyle}"/>
          <Setter TargetName="txtTitle" Property="Style" Value="{StaticResource editingStyle}"/>
        </DataTrigger>
        <DataTrigger Binding="{Binding Title}" Value="Paragraph">
          <Setter TargetName="txtTitle" Property="Visibility" Value="Collapsed" />
        </DataTrigger>

		// i want to create this, how to detect the child in the binding?	

		<DataTrigger Binding="{Binding ChildrenList.Child}">

          <Setter TargetName="txtTitle" Property="Style" Value="{StaticResource alignCenter}" />

        </DataTrigger>

		<DataTrigger Binding="{Binding ChildrenList.Child.Child}">

          <Setter TargetName="txtTitle" Property="Style" Value="{StaticResource alignRight}" />

        </DataTrigger>

</DataTemplate.Triggers> </DataTemplate>

</DataTemplate.Triggers> </DataTemplate>
