您正在使用新的
控制模板更改DataGridColumnHeader.Template
CustomCheckBoxTemplate
提供了一个DataGridTemplateColumn.HeaderTemplate
asDataTemplate
，它以DataGridColumnHeader.ContentTemplate
为目标。但是，您的ControlTemplate
没有在内部使用DataGridColumnHeader.ContentTemplate
，因此CustomCheckBoxTemplate
的HeaderTemplate部分将被忽略
如果它适合您，只需定义DataGridColumnHeader.ContentTemplate
，而不是在您的样式中定义DataGridColumnHeader.Template
（行为会稍有不同）
没有测试所有部分，因此我的建议中可能仍然存在错误
编辑实际上，关于ContentPresenter
的最后一部分并没有阻止txtId
文本框。下面是一个想法，ControlTemplate
使用触发器
根据设置的ContentTemplate
属性更改可见部分。注意：我在测试中更改了一些小细节，如列定义宽度
<ControlTemplate TargetType="{x:Type DataGridColumnHeader}" >
<Border x:Name="Border"
Padding="2"
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}">
<Grid>
<Grid x:Name="LayoutGrid"
Visibility="Collapsed">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<StackPanel Orientation="Vertical">
<TextBlock Text="{Binding Content, RelativeSource={RelativeSource Mode=TemplatedParent}}"/>
<TextBox x:Name="txtId" Width="100" />
</StackPanel>
</Grid>
<ContentPresenter
x:Name="TemplatedContent"
Visibility="Visible"
Content="{Binding Content, RelativeSource={RelativeSource Mode=TemplatedParent}}"
ContentTemplate="{TemplateBinding ContentTemplate}"/>
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="ContentTemplate" Value="{x:Null}">
<Setter Property="Visibility" TargetName="TemplatedContent" Value="Collapsed"/>
<Setter Property="Visibility" TargetName="LayoutGrid" Value="Visible"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
Hi，如果我的回答能解决您的问题（相关部分主要在编辑部分），或者需要任何澄清，我很乐意得到一些反馈。
