WPF DataGrid行和列样式问题 [英] WPF DataGrid row and column Style question

问题描述

我需要突出显示Datagrid的MouseOver行，这个样式似乎很简单：

I have a need to highlight the MouseOver row of the datagrid, which seems to be easy with this style:

<Style TargetType="DataGridRow">
    <Style.Triggers>
        <Trigger Property="IsMouseOver" Value="True">
            <Setter Property="Background" Value="Green"/>
        </Trigger>
    </Style.Triggers>
</Style>

问题是我还有一些只读单元格的样式，定义为：

The problem is that I also have a style for some readonly cells defined as:

<Style TargetType="DataGridCell">
    <Style.Triggers>
        <Trigger Property="IsReadOnly" Value="True">
            <Setter Property="Background" Value="LightGoldenrodYellow"/>
        </Trigger>
    </Style.Triggers>
</Style>

因此，这些只读单元格不会得到MouseOver背景。如何解决这个冲突？您的帮助非常感激。

As a result, those readonly cells don't get MouseOver background. How do I solve this conflict? Your help is much appreciated.

推荐答案

这不是冲突。 MouseOver事件适用于不可读的正常行和单元格。

It is not a conflict. The MouseOver event is intended to work for normal row and cell which is not readonly.

您应该为此问题添加MultiTrigger。

You should add a MultiTrigger for this problem.

样本：

  <MultiTrigger>
    <MultiTrigger.Conditions>
      <Condition Property="IsReadOnly" Value="true" />
      <Condition Property="IsMouseOver" Value="true" />
    </MultiTrigger.Conditions>
    <Setter Property="Background" Value="Green"/>
  </MultiTrigger>

代码适用于DataGridCell的样式。完成的代码示例将是：

The code is valid for a style for DataGridCell. The completed code sample would be:

<Style TargetType="DataGridCell">    
<Style.Triggers>        
      <MultiTrigger>
        <MultiTrigger.Conditions>
          <Condition Property="IsReadOnly" Value="true" />
          <Condition Property="IsMouseOver" Value="true" />
        </MultiTrigger.Conditions>
        <Setter Property="Background" Value="Green"/>
      </MultiTrigger>
</Style.Triggers>
</Style>
