                </DataTemplate>

            </DataGrid.RowDetailsTemplate>

        </DataGrid>

Answer 1

要以编程方式获取价值，您可以尝试此方法

dgUsers.LoadingRowDetails += dgUsers_LoadingRowDetails;

 void dgUsers_LoadingRowDetails(object sender, DataGridRowDetailsEventArgs e)
       {
         var textBlockValue = (e.DetailsElement as FrameworkElement).FindName("txtSellerId") as TextBlock;
       }

Answer 2

您可以将模型绑定到数据网格行，并在代码隐藏中使用它。

var user = (User)myDataGrid.SelectedItem;
var userId = user.Id;

一个简单的示例：DataGrid with row details
