gridview汇总问题


如图 我下面的代码有问题吗？为什么汇总不了  

C# code

Decimal mysum4 = 0;Decimal sum2=0； protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)｛           if (e.Row.RowType == DataControlRowType.DataRow)        {            if (!string.IsNullOrEmpty(e.Row.Cells[2].Text.ToString()) && e.Row.Cells[2].Text.ToString() != "&nbsp;")            {                 sum2 += decimal.Parse(e.Row.Cells[2].Text.ToString());                mysum4 = mysum4 + sum2;            }         ｝        if (e.Row.RowType == DataControlRowType.Footer)        {            e.Row.Cells[0].Text = "<span align='center' style='color:red'>合计:</span>";                      e.Row.Cells[2].Text = "<span align='center' style='color:red'>" + mysum4.ToString() + "</span>";         ｝｝

C# code

if (e.Row.RowIndex >= 0)            {                string xxx = e.Row.Cells[3].Text;                sum += Convert.ToDouble(e.Row.Cells[3].Text);            }            else if (e.Row.RowType == DataControlRowType.Footer)            {                e.Row.Cells[2].Text = "总计：";                e.Row.Cells[3].Text = sum.ToString();                           }
