如何在ASP.NET C＃中将多个gridview行数据保存到数据库

Question

I have a gridview control in my project in which i wanted to save multiple gridview rows back to the database. How do i get save all rows through looping. Please help me to overcome this problem.

//Save TestDetails

   foreach (GridViewRow rw in GridView1.Rows)
    {
            var n = new TestDetail
            {
                ServiceId = Convert.ToInt32(GridView1.DataKeys[rw.RowIndex].Value),
                Service = rw.Cells[1].Text.ToString(),  //getting input error
                Price = Convert.ToInt32(rw.Cells[2].Text.ToString())  //getting input error
            };

            using (var context = new DiagEntities())
            {
                context.TestDetail.Add(n);
                context.SaveChanges();
            }
     }

If you are in edit mode, you could check the control collection of the particular cell... it should context the textbox containing the value.

Service = ((TextBox)(rw.Cells[1].Controls[0]).Text.ToString(),
Price = Convert.ToInt32(((TextBox)(rw.Cells[1].Controls[0]).Text.ToString())
