如何将WPF按钮添加到每个WPF DataGrid列中

Question

我的项目中有一个WPF数据网格样式。现在我想在每一行中添加一些按钮，另一方面，我想为按钮设置特定的样式。

<Style TargetType="DataGrid">

正如您所看到的，文本或组合框有一些样式，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？

Answer 1

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？

这就是在WPF DataGrid中为每行添加button的方法。

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

因此，您创建了一个DataGridTemplateColumn，在其中定义了DataTemplate，在内部可以设置Button或任何其他要为每行显示的UI元素，例如CheckBox。

现在，进入问题的第二部分。

如何为其添加特定样式？

您可以像定义其他按钮一样定义此按钮的样式，也可以为其分配Style资源或模板。类似下面的

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

或者指定样式资源。

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