从DataGrid C＃WPF获取数据

Question

如何从datagrid获取数据？

combobox xml代码：

我将组合连接到表MahName

combobox1.ItemsSource = database.Mahs.ToList();

combobox1.DisplayMemberPath = "MahName";

这是代码datagrid

    <DataGrid.Columns>
        <DataGridTextColumn Header="کد محصول" Binding="{Binding MahID}">
            <DataGridTextColumn.HeaderStyle>

</DataGrid>

我想当combobox.text = datagrid中的“ MahName”然后datagrid / 1000中的“ Mahg1”然后* datagrid中的“ Mahf1” ...

数据网格/ 1000中的“ Mahg10”，然后*数据网格中的“ Mah10”

Mahf是价格，而Mahg是重量

我该怎么办？
