When the GridView is bound to a data source control, the GridView is composed by enumerating the DataSource and building one row at a time. As each GridView row is databound, the GridView's RowDataBound event is fired. This provides page developers an opportunity to tap into the GridView creation process at row-level granularity.

C#

int quantityTotal = 0;
void detailsGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        quantityTotal += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, _
          "Quantity"));
    }
    else if (e.Row.RowType == DataControlRowType.Footer)
    {
        e.Row.Cells[0].Text = "Totals:";
        e.Row.Cells[1].Text = quantityTotal.ToString("d");
        e.Row.Cells[1].HorizontalAlign = HorizontalAlign.Right;
        e.Row.Font.Bold = true;
    }
}

Hi, try this:

C#

int sum = 0;
for (int i = 0; i < dataGridView1.Rows.Count; ++i)
{
    sum += Convert.ToInt32(dataGridView1.Rows[i].Cells[1].Value);
}
label1.text = sum.ToString();
