WPF Grid - 如何为一列应用样式? [英] WPF Grid - How to apply a style for just one column?

问题描述

我有一个 WPF 网格，其中包含许多行和列，都包含诸如 TextBlocks 和 TextBoxes 之类的内容.

I have a WPF Grid with many rows and columns, all containing things like TextBlocks and TextBoxes.

对于这种特定情况，我希望第 1 列中的所有内容都有填充，并且第 2 列中的所有内容都正确对齐.必须在网格中的每个项目上设置这些属性似乎是非常非 WPF 的.

For this specific situation I want all the stuff in column 1 to have padding, and all the stuff in column 2 to be aligned right. It seems to be very non-WPF to have to set those properties on each item in the grid.

我知道我可以通过执行以下操作为网格中的所有 TextBlocks 创建样式:

I know I can create a style for all TextBlocks within a grid by doing something like this:

<Grid>
  <Grid.Resources>
    <Style TargetType="{x:Type TextBox}">
      <Setter Property="HorizontalAlignment" Value="Right"/>
    </Style>
  </Grid.Resources>
</Grid>

但是有没有办法将该样式仅应用于第 2 列中的控件?

But is there a way to apply that style to only the controls in say, column 2?

我应该使用不同的控件吗?

Should I be using a different control?

推荐答案

这是我通常做的:

<Style TargetType="{x:Type TextBlock}" BasedOn="{StaticResource {x:Type TextBlock}}">
    <Style.Triggers>
        <Trigger Property="Grid.Column" Value="0">
            <Setter Property="Margin" Value="0,0,2,0" />
        </Trigger>

        <Trigger Property="Grid.Column" Value="2">
            <Setter Property="Margin" Value="20,0,2,0" />
        </Trigger>
    </Style.Triggers>
</Style>
