关于gridview 合计及小计(在线等待.....)
在web中 把数据绑定gridview 上
实现 如下格式
名称 数据 单价 金额
a b c d
a c d f
小计 b+c (c+d)/2 d+f
bc d c f
bc c e h
小计 d+c (c+e)/2 f+h
总计 b+c+d+c d+f+f+h
请大家帮忙,
谢谢
------解决方案--------------------舉個例子,在下面事件里面寫方法
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
在
ds 你綁定的數據源:
int count=0;
int count1 = 0 ;
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
count += int.Parse(ds.Tables[0].Rows[i][ "数据 "].ToString());
count1 += int.Parse(ds.Tables[0].Rows[i][ "单价 "].ToString());
}
int sum = count;
int nAv = count1/ds.Tables[0].Rows.Count;
if (e.Row.RowType == DataControlRowType.Footer)//判定当前的行是否属于datarow最后一行
{
DataRowView view = (DataRowView)e.Row.DataItem;
TextBox ts= (TextBox)e.Row.FindControl( "textBox1 ");
ts.Text = "和為: "+sum.toString();
}
}
.......
------解决方案--------------------你在数据库中 用视图写好了再绑定不就完了? 例:
SELECT dbo.AutoQuiz.QuizID, dbo.AutoQuiz.DealerID, dbo.AutoQuiz.Qtitle,
dbo.AutoQuiz.QuizDate, (dbo.AutoQuizBack.BackText+dbo.AutoQuizBack.BackDate) as 小计★★★★★★★
dbo.AutoQuizBack.DealerID AS DealerIDS
FROM dbo.AutoQuiz INNER JOIN
dbo.AutoDealer ON dbo.AutoQuiz.DealerID = dbo.AutoDealer.DealerID INNER JOIN
dbo.AutoQuizBack ON dbo.AutoQuiz.QuizID = dbo.AutoQuizBack.QuizID
