GridViewRow row = (GridViewRow)txtMark.NamingContainer;
string query = "UPDATE EDU_Lesson2 SET Mark = @Mark WHERE Id = @Id";
string constr = ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString;
using (SqlConnection con = new SqlConnection(constr))

using (SqlCommand cmd = new SqlCommand(query, con))
{
cmd.Parameters.AddWithValue("@Mark", txtMark.Text);
cmd.Parameters.AddWithValue("@Id", row.Cells[0].Text);
con.Open();
cmd.ExecuteNonQuery();
