c# - 如何在行双击而不是项目数组索引上获取列名的数据网格单元格值？

Question

如何datagrid在行双击时获取列名的单元格值，而不是项目数组索引？

我生成带有查询的列：

private void grid_supplier_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    if (grid_supplier.SelectedItem == null) return;
    DataRowView dr = grid_supplier.SelectedItem as DataRowView;
    DataRow dr1 = dr.Row;

    txt_hiden_edit_id.Text = Convert.ToString(dr1.ItemArray[0]);
    comb_supplier_name.SelectedValue = Convert.ToString(dr1.ItemArray[1]);
    datepicker_supplier.SelectedDate = DateTime.Parse(Convert.ToString(dr1.ItemArray[2]));
    txt_payment.Text = Convert.ToString(dr1.ItemArray[3]);
    txt_reciept_number.Text = Convert.ToString(dr1.ItemArray[4]);

    txt_quantity.Text = Convert.ToString(dr1.ItemArray[5]);
    txt_code.Text = Convert.ToString(dr1.ItemArray[6]);
}
