[英]How do I customize the display of column headers in my WPF Datagrid?
I am trying to customize a DataGrid. 我正在尝试自定义DataGrid。 I want to insert some content above the column headers.
我想在列标题上方插入一些内容。 I am trying to use the ControlTemplate to do this.
我正在尝试使用ControlTemplate来执行此操作。 I have my XAML code below.
我的XAML代码如下。 My problem is that the
<ContentPresenter />
is not outputting anything. 我的问题是
<ContentPresenter />
没有输出任何东西。 When I load the page, the after
TextBlock appears directly below the before
TextBlock with nothing in between. 当我加载页面时,
after
TextBlock直接出现before
TextBlock before
,其间没有任何内容。 I want to display the column headers in that space. 我想在该空间中显示列标题。
<DataGrid ItemsSource="{Binding List}" AutoGenerateColumns="True">
<DataGrid.Template>
<ControlTemplate>
<StackPanel Orientation="Vertical">
<TextBlock>before</TextBlock>
<ContentPresenter /> <!-- outputs nothing -->
<TextBlock>after</TextBlock>
<ItemsPresenter />
</StackPanel>
</ControlTemplate>
</DataGrid.Template>
</DataGrid>
How do I display the column headers between the before
TextBlock and the after
TextBlock? 如何
before
TextBlock before
和TextBlock after
显示列标题? My List object is simply a BindingList of some generic class that has a couple of public properties. My List对象只是某个泛型类的BindingList,它具有一些公共属性。
I found the answer. 我找到了答案。 I should use
<DataGridColumnHeadersPresenter />
instead of <ContentPresenter />
. 我应该使用
<DataGridColumnHeadersPresenter />
而不是<ContentPresenter />
。 So my code that works looks like: 所以我的代码看起来像:
<DataGrid ItemsSource="{Binding List}" AutoGenerateColumns="True">
<DataGrid.Template>
<ControlTemplate>
<StackPanel Orientation="Vertical">
<TextBlock>before</TextBlock>
<DataGridColumnHeadersPresenter />
<TextBlock>after</TextBlock>
<ItemsPresenter />
</StackPanel>
</ControlTemplate>
</DataGrid.Template>
</DataGrid>
