在WPF中，有没有办法绑定兄弟属性？ [英] In WPF, is there a way to bind to sibling properties?

问题描述

我有一系列 TextBlock 和 TextBox 控件。有没有办法将 Style 应用于 TextBlock ，以便他们可以立即将数据绑定到控件？

I have a series of TextBlock and TextBox controls. Is there a way to apply a Style to the TextBlocks such that they can databind to the control immediately after them?

我想要这样做：

<Resources..>
    <Style x:Key="BindToFollowingTextBoxSibling">
        <Setter Property="TextBlock.Text" Value="{Binding RelativeSource={RelativeSource FollowingSibling}, Path=Text, Converter={StaticResource MyConverter}}" />
        <Setter Property="TextBlock.Background" Value="{Binding RelativeSource={RelativeSource FollowingSibling}, Path=Text, Converter={StaticResource TextToBrushConverter}}" />
        ... More properties and converters.
    </Style>
</Resources>

...

<TextBlock Style="{StaticResource BindToFollowingTextBoxSibling}"/>
<TextBox/>

<TextBlock Style="{StaticResource BindToFollowingTextBoxSibling}"/>
<TextBox/>
<TextBlock Style="{StaticResource BindToPreviousTextBoxSibling}"/>

这样的事情甚至可能吗？

Is something like this even possible?

推荐答案

我认为在这种情况下最好的事情是由ElementName绑定：

I think the best thing to do in this case is bind by ElementName:

<TextBlock Text="{Binding ElementName=textBox1, Path=Text}" />
<TextBox x:Name="textBox1">this is the textBox's 1 text</TextBox>
<TextBlock Text="{Binding ElementName=textBox2, Path=Text}" />
<TextBox x:Name="textBox2">this is the textBox's 2 text</TextBox>

它将实现类似的东西。这是否适合你？

It will achieve something similar. Does this work for you?
