wpf - 如何将 WPF 按钮添加到每个 WPF DataGrid 列

如您所见，Texts 或 ComboBox 有一些样式，但按钮没有样式。如何向每一行添加按钮并设置特定的按钮样式？

你问题的第一部分

如何为 Wpf 数据网格中的每一行添加一个按钮？

这就是button在WPF DataGrid.

<DataGridTemplateColumn>
  <DataGridTemplateColumn.CellTemplate> 
    <DataTemplate> 
      <Button Click="BtnClicked">Details</Button> 
    </DataTemplate> 
  </DataGridTemplateColumn.CellTemplate> 
</DataGridTemplateColumn>  

因此，您创建一个DataGridTemplateColumn您定义的DataTemplateand inside 和您可以设置的 InsideButton或您想要为每一行显示的任何其他 UI 元素，例如 a CheckBox。

现在，来到你问题的第二部分。

如何为其添加特定样式？

好吧，您可以像定义任何其他按钮一样为该按钮定义样式，也可以为其分配Style资源或模板。像下面这样的东西，

<DataGridTemplateColumn>
  <DataGridTemplateColumn.CellTemplate> 
    <DataTemplate> 
      <Button Click="BtnClicked" Background="White" Foreground="Black" BorderThickness="2" BorderColor="Black">Details</Button> 
    </DataTemplate> 
  </DataGridTemplateColumn.CellTemplate> 
</DataGridTemplateColumn>  

或分配样式资源。

<DataGridTemplateColumn>
  <DataGridTemplateColumn.CellTemplate> 
    <DataTemplate> 
      <Button Click="BtnClicked" Style="MyBtnStyle">Details</Button> 
    </DataTemplate> 
  </DataGridTemplateColumn.CellTemplate> 
</DataGridTemplateColumn>
