DataGridTextColumn 标题 DataTemplate [英] DataGridTextColumn Header DataTemplate

问题描述

这可能(希望)有一个微不足道或非常简单的答案.

This may (hopefully) have a trivial or very simple answer.

假设我想要为我的 DataGrid 自定义标题.我可以这样使用 DataTemplate:

Suppose I want customized headings for my DataGrid. I can use a DataTemplate as so:

<DataGridTextColumn Binding="{Binding Name}">
    <DataGridTextColumn.HeaderTemplate>
        <DataTemplate>
            <TextBlock Text="Header Text" TextWrapping="Wrap"/>
        </DataTemplate>
    </DataGridTextColumn.HeaderTemplate>
</DataGridTextColumn>

但是，如果有很多列，使用类似的东西就不会那么麻烦

However, if there are many columns it is less cumbersome to be able to use something like

<DataGridTextColumn Binding="{Binding Name}">
    HeaderTemplate="{StaticResource ColumnHeaderTemplate}"
</DataGridTextColumn>

其中 ColumnHeaderTemplate 是我的自定义 DataTemplate.我的问题是如何将标题文本"传递给 DataTemplate?

where ColumnHeaderTemplate is my custom DataTemplate. My question is how do I pass the "Header Text" to the DataTemplate?

推荐答案

您可以通过绑定 TextBlock.Text 来实现，也可以对 DataGrid<中的所有列标题进行绑定/code> 通过将标题的 ContentTemplate 更改为您的自定义 TextBlock，然后将 Header 设置为您想要显示的文本.它也适用于自动生成的列

You can do it by binding TextBlock.Text and you can do it either for all column headers in a DataGrid by changing ContentTemplate of header to be your custom TextBlock and then just set Header to text you want to display. It will also apply to automatically generated columns

<DataGrid ...>
   <DataGrid.Resources>
      <Style TargetType="{x:Type DataGridColumnHeader}">
         <Setter Property="ContentTemplate">
            <Setter.Value>
               <DataTemplate>
                  <TextBlock Text="{Binding}" TextWrapping="Wrap"/>
               </DataTemplate>
            </Setter.Value>
         </Setter>
      </Style>
   </DataGrid.Resources>
   <DataGrid.Columns>
      <DataGridTextColumn Binding="{Binding Name}" Header="Header Text">
   </DataGrid.Columns>
</DataGrid>       

或者也可以按列执行，只需更改标题模板中的 TextBlock.Text 即可使用绑定，如上所述

or can also do it per column just change TextBlock.Text in you header template to use binding, as above

<TextBlock Text="{Binding}" TextWrapping="Wrap"/>

然后您的列可能如下所示:

and then you column could look like this:

<DataGridTextColumn 
    Binding="{Binding Name}" 
    HeaderTemplate="{StaticResource ColumnHeaderTemplate}"
    Header="Header Text"/>
