wpf - 如何使用 WPF 数据绑定(bind)处理外键？

Question

我在 WPF 中有一个 ListView，它数据绑定(bind)到我从数据库中提取的基本表。 ListView 的代码如下:

<ListView Canvas.Left="402" Canvas.Top="480" Height="78" ItemsSource="{Binding}" Name="lsvViewEditCardPrint" Width="419">
   <ListView.View>
      <GridView>
         <GridViewColumn DisplayMemberBinding="{Binding Path=IdCst}">Set</GridViewColumn>
         <GridViewColumn DisplayMemberBinding="{Binding Path=Language}">Language</GridViewColumn>
         <GridViewColumn DisplayMemberBinding="{Binding Path=Number}">Number</GridViewColumn>
         <GridViewColumn DisplayMemberBinding="{Binding Path=IdArt}">Artwork</GridViewColumn>
      </GridView>
   </ListView.View>
</ListView>

IdCst 列是单独表的外键，我想显示该表中的实际名称字段，而不仅仅是 Id。有谁知道如何设置数据绑定(bind)，或者是否有一个事件，例如 OnItemDataBound，我可以拦截以修改显示？

本博客 post可能有帮助:

...I assumed the foreign key should be bound to the ‘SelectedValue’ property, and there is an ItemSource that I can bind to my fact table so the drop down is populated.

At this point my dropdown worked, but nothing would appear in the combobox. I finally noticed a ‘SelectedItemPath’ property - I assumed this would be the name of the field in my dropdown that was associated to my foreign key. Sure enough, that’s exactly what it is.
