datagrid 统计功能 求助？？？

Question

我用的.net 2005 
想统计某一列的总和
如何实现，请高手指教.
不胜感激。

Answer 1

RowDataBound的时候累加一下就行了！~~
百度一下GridView 72绝技，，那有现成的！~~

Answer 2

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intprotected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)    {                if (e.Row.RowIndex >= 0)        {            sum += Convert.ToDouble(e.Row.Cells[6].Text);        }        else if (e.Row.RowType == DataControlRowType.Footer)        {            e.Row.Cells[5].Text = "总薪水为：";            e.Row.Cells[6].Text = sum.ToString();            e.Row.Cells[3].Text = "平均薪水为：";            e.Row.Cells[4].Text = ((int)(sum / GridView1.Rows.Count)).ToString();                    }    }
