WPF DataGrid RowHeader 数据绑定 [英] WPF DataGrid RowHeader databinding

问题描述

我有一个 DataGrid，绑定到一个 DataTable.我想在 RowHeader 中显示文本，以实现这样的目标:

I have a DataGrid, bound to a DataTable. I want to display text in the RowHeader, to achieve something like this:

         Col0      Col1      Col2      Col3
Table |    1    |    3    |    5    |    6    |
Chair |    3    |    2    |    1    |    8    |

这可能吗?如果可能，我该怎么做?

Is this possible and if so, how can I do this?

推荐答案

我尝试了两种答案，但都不适合我.基本上我要做的就是将它们混合在一起.

I tried both answers, and neither worked for me. Essentially what I had to do was mix them together.

这对我有用:

<DataGrid name="ui_dataGrid>
    <DataGrid.RowHeaderTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding RelativeSource={RelativeSource Mode=FindAncestor, 
                                      AncestorType={x:Type DataGridRow}}, 
                                      Path=Item.Header}"/>
        </DataTemplate>
    </DataGrid.RowHeaderTemplate>
</DataGrid>

诀窍是找到祖先 DataGridRow，然后将 TextBlock.Text 属性绑定到您关心的它的 Item 属性，在本例中为 Header(用 XAML 说可能比用英语说得更容易).

The trick is to find the ancestor DataGridRow, then Bind the TextBlock.Text attribute to its Item's property that you care about, in this case Header (easier said in XAML than English maybe).

然后在 .xaml.cs 中:

Then in the .xaml.cs:

ui_dataGrid.ItemsSource = dataSource.Rows;

注意每个 Row 对象都有一个 Header 属性，这也是我要绑定的.

N.B. Each Row object has a Header property which is what I'm binding too.
