I am working on Windows Application and I am stuck in an issue. Suppose have a gridview in which I have to add the value of a particular column.And at the end of the rows it will display the result.Like,

No. Item Rate

1 Pencil 10
2 Box 20

Total: 30

I have written this code,
private void datagridview_CellValueChanged(object sender, DataGridViewCellEventArgs e)
           if (e.ColumnIndex == 2)
               decimal Total = 0;
               for (int i = 0; i < datagridview.Rows.Count; i++)
                   if (Convert.ToString(datagridview.Rows[i].Cells[2].Value) != "")
                       decimal GrossAmnt = Convert.ToDecimal(datagridview.Rows[i].Cells[2].Value.ToString());
                       Total = GrossAmnt + Total;
                       datagridview[2, datagridview.Rows.Count].Value = Total.ToString();


when I execute this it shows me an error;
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Anybody is there please help me to solve this.

Your gridView is bind to a database ? or it will be filled by user ?

no its bind to database.

You have to calculate the total and add a row in your datasource with the result in.
Shivani Dash 19-Apr-13 2:48am the result should show at the end of the gridview row..where the row finished.

Solution 1

int count = 0;
            for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
                count = count+ Convert.ToInt32(ds.Tables[0].Rows[i][2].ToString());
            DataRow dr = ds.Tables[0].NewRow();
            dr[1] = "Total::";
