我在 wpf 中有一个基本样式和一个样式。
基本风格是:
<Style x:Key="BaseTextBox" TargetType="{x:Type TextBox}">
<Setter Property="Background" Value="#DDFFDD" />
<Setter Property="MinWidth" Value="75" />
<Setter Property="behaviors:OCCInteraction.Triggers" Value="{StaticResource ResourceKey=validationTrigger}" />
<Style.Triggers>
<Trigger Property="Validation.HasError" Value="true">
<Setter Property="Background" Value="#FFDDDD"/>
<Setter Property="ToolTip" Value="{Binding Path=(Validation.Errors)[0].ErrorContent, RelativeSource={x:Static RelativeSource.Self}}" />
</Trigger>
</Style.Triggers>
</Style>
而具体的风格是:
<Style x:Key="EditableTextBox" TargetType="{x:Type TextBox}" BasedOn="{StaticResource ResourceKey=BaseTextBox}">
<Setter Property="Validation.ErrorTemplate">
<Setter.Value>
<ControlTemplate>
<StackPanel Orientation="Horizontal">
<Border BorderBrush="Red" BorderThickness="1" Padding="0" Margin="0">
<AdornedElementPlaceholder Margin="0"/>
</Border>
<TextBlock Text="test" />
<Image Style="{StaticResource ResourceKey=WarningImage}"/>
<TextBlock Text="{Binding Path=(Validation.Errors)[0].ErrorContent, RelativeSource={RelativeSource Mode=Self,AncestorLevel=2}}" />
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
现在我想将验证错误文本添加到图像旁边的文本块中。但是相同的绑定路径不起作用。我尝试了不同的绑定,但我不知道如何访问与基本样式相同的绑定。
感谢帮助 :)
