GridView 在Footer加上自动求和行

ShowFooter="True"

private double sum = 0;//取指定列的数据和，你要根据具体情况对待可能你要处理的是int
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{

if (e.Row.RowIndex >= 0)
{
sum += Convert.ToDouble(e.Row.Cells[5].Text)
}
if (e.Row.RowIndex >= 0)
{
sum += Convert.ToDouble(e.Row.Cells[5].Text);
}
else if (e.Row.RowType == DataControlRowType.Footer)
{
e.Row.Cells[4].Text = "总价格为：";
e.Row.Cells[5].Text = sum.ToString();
e.Row.Cells[2].Text = "平均价格为：";
e.Row.Cells[3].Text = ((int)(sum / GridView1.Rows.Count)).ToString();

}

}
