           gridDataContext datacontext = new gridDataContext();
           registration registrationRow = MyDataGrid.SelectedValue as registration;
           int m = registrationRow.RegId;
           //registration Registration = (from p in datacontext.registrations where p.RegId == registrationRow.RegId select p).Single();
           registration Registration = datacontext.registrations.Where(A => A.RegId == m).Single();
           Registration.Name = registrationRow.Name;
           Registration.FName = registrationRow.FName;
           datacontext.SubmitChanges();
           MessageBox.Show("Row Updated Successfully");
           LoadCustomerDetail();
       }
       catch (Exception ex)
       {

           return;
       }
   }

推荐答案

最后我得到了解决方案......我们可以创建一个存储行数据的对象。现在我可以访问每个单元格项目



这里是代码： -

finally I got solution... we can create an object which is store row data. now i can access each cell item like that

here is code:-

private void btnEdit_Click(object sender, RoutedEventArgs e)
    {
        try
        {
        object item = MyDataGrid.SelectedItem;
            gridDataContext datacontext = new gridDataContext();

            int m = int.Parse((MyDataGrid.SelectedCells[0].Column.GetCellContent(item) as TextBlock).Text);

            registration Registration = datacontext.registrations.Where(A => A.RegId == m).Single();
            Registration.Name = (MyDataGrid.SelectedCells[1].Column.GetCellContent(item) as TextBlock).Text;
            Registration.FName = (MyDataGrid.SelectedCells[2].Column.GetCellContent(item) as TextBlock).Text;
            datacontext.SubmitChanges();
            MessageBox.Show("Row Updated Successfully");
