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？
