DataGrid 行详细信息中的嵌套 Datagrid

Question

我有一个嵌套在主 Datagrid 的 RowDetails 中的 Datagrid。我试图访问嵌套的 Datagrid，但没有成功。

这是我的代码：

XML

   <DataGrid x:Name="datagrid_transactions" Grid.Column="1" Grid.Row="0" Margin="5" HeadersVisibility="Column" GridLinesVisibility="None" ScrollViewer.CanContentScroll="False" MouseDoubleClick="Datagrid_wafers_MouseDoubleClick" SelectionChanged="Datagrid_transactions_SelectionChanged">

和我背后的代码

Getting data from DB and

        if (datatable.Rows.Count != 0)
        {
            foreach (DataRow dt in datatable.Rows)
            {
                Transaction = new Transaction
                {
                    ID = dt[0].ToString(),
                    Tool_Model = dt[1].ToString(),
                    UTID = dt[2].ToString(),
                    Username = dt[4].ToString(),
                    Date_Created = dt[5].ToString(),
                    Customer = dt[7].ToString()
                };
                datagrid_transactions.Items.Add(Transaction);
            }
        }

此代码填充名为 datagrid_transactions

的主 DataGrid

如何填充名为 datagrid_wafers_transaction 的嵌套文件，因为我无法访问它

谢谢
