my question depends upon my need to populate a table in database, from a gridview. I've populated that gridview from a datatable from ViewState. Can anybody help me?

What I have tried:

C#

string str = ConfigurationManager.ConnectionStrings["ConStr"].ConnectionString;
                SqlConnection con = new SqlConnection(str);
                con.Open();
                SqlCommand cmd = new SqlCommand("Select TOP 1 * from Bookings", con);
                SqlDataReader reader = cmd.ExecuteReader();
                if(reader.Read())
                {
                    bookingId = Convert.ToInt32(reader["Id"]);
                }

                Booking_Tax(bookingId);//Here I have multiple entries for taxes with same bookingId

Hi,

To you insert the records into the database, you need to read each row in the gridview by inserting the records.

Here! An example.

C#

private void Booking_Tax(Int32 id)
        {
            string str = ConfigurationManager.ConnectionStrings["ConStr"].ConnectionString;
            SqlConnection con = new SqlConnection(str);
            con.Open();
            SqlCommand cmd = new SqlCommand();
            cmd.Connection = con;
            cmd.CommandType = CommandType.Text;

            //read each row in your gridview
            foreach (GridViewRow gvrow in this.grd_result.Rows)
            { 
                //insert query
                cmd.CommandText = "INSERT INTO mytable (id, tax1, taxt2) VALUE (" + id.ToString() + ", " + gvrow.Cells[0].Text + ", " + gvrow.Cells[2].Text + ")";

                //execute the query for insert record in database
                cmd.ExecuteNonQuery();
            }
        }
