GridView自動求和、求平均值小計

轉自清清月兒gridview72絕技，略有改動
前臺：唯一的花頭就是設定ShowFooter="True"
private double sum = 0;//取指定列的資料和，你要根據具體情況對待可能你要處理的是int
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
sum += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "amount").ToString());
}
else if (e.Row.RowType == DataControlRowType.Footer)
{
e.Row.Cells[5].Text = "總薪水為：";
e.Row.Cells[6].Text = sum.ToString();
e.Row.Cells[3].Text = "平均薪水為：";
e.Row.Cells[4].Text = ((int)(sum / GridView1.Rows.Count)).ToString();
}
}
