gridview 合计行实现

1：首先给gridview添加ShowFooter="true" 属性

2：在RowDataBound 实现数据合计

protected override void OnMainGridRowDataBound(object sender, GridViewRowEventArgs e)     {        

base.OnMainGridRowDataBound(sender, e);

 if (e.Row.RowType == DataControlRowType.DataRow)        

    {             

 clickcount += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "PVCount"));            

ipconut += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "IPCount"));            

amoutcount += Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "AmountQR"));            

talkcount += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "talkCount"));            

ordercount += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "CountQR"));            

shouamount += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "AmountQS"));            

shoucount += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "CountQS"));

}        

else if (e.Row.RowType == DataControlRowType.Footer)        

{            

e.Row.Cells[0].Text = "合计";            

e.Row.Cells[4].Text = clickcount.ToString();            

e.Row.Cells[5].Text = ipconut.ToString();            

e.Row.Cells[6].Text = amoutcount.ToString("0.00");            

e.Row.Cells[7].Text = talkcount.ToString();            

e.Row.Cells[8].Text = ordercount.ToString();            

e.Row.Cells[9].Text = shouamount.ToString();            

e.Row.Cells[10].Text = shoucount.ToString();            

e.Row.Font.Bold = true;        

}

    }
