Question

string total;
int totalmarks = 0;

foreach (GridViewRow row in GridView1.Rows)
            {

                int rowcount = this.GridView1.Rows.Count;

                for (int i = 0; i < rowcount; i++)
                {
                    total = row.Cells[3].Text;
                    totalmarks = Convert.ToInt32(total);

                    totalmarks +=totalmarks ;
                }


            }

            totalmarksLabel.Text = Convert.ToString(totalmarks);

I use that portion of code to get the value from cell[3] for every rows in gridview. Then i try to sum up every value from every row and display it using label. however, when i run my code, the value displayed is 510 where it supposed to be 170.

** value for row [1], row[2], row[3] are 60, 30 and 80 respectively.

i found the problem, i have an extra loop. after correcting it, the value shown is 160 instead of 170. the mystery being where is the other ’10’ disappear?? its 3 a.m here in Malaysia and i’am stuck.

Answer 1

I have corrected my code like below. and it works

int totalMarks=0;

        foreach (GridViewRow row in GridView1.Rows)
        {

                total = Convert.ToInt32(row.Cells[3].Text);

               totalMarks = totalMarks + total;



        }



        totalMarks Label.Text = Convert.ToString(totalMarks );
