这是我的报告在这里我想要小计的车辆明智。
那么我如何在gridview中添加一个新行来查找小计车辆没有明智的????
query =从[事务]中选择transdate，orderno，vehicleno，oiltype，qty，price，amount，其中custid =+ int.Parse（lblid.Text.Trim（））+和orderno in（+ slipall.ToString （）+）和invoicestatus ='true'命令由vehicleno，transdate;
cmd = new SqlCommand（query，con）;
// SqlCommand cmd = new SqlCommand（select * from [transaction]，con）;
SqlDataReader reader1 = cmd.ExecuteReader（）;
DataRow nr = dt.NewRow（）;
if（reader1.Read（））
{
DataRow dr = dt.NewRow（）;
nextno = reader1 [vehicleno]。ToString（）;
afterno = reader1 [vehicleno ] .ToString（）;
amt = reader1 [amount]。ToString（）;
dr [DATE] = reader1 [transdate]。ToString（）;
dr [O.NO] = reader1 [orderno]。ToString（）;
dr [ VEHICLE NO] = reader1 [vehicleno]。ToString（）;
dr [PARTICULARS] = reader1 [oiltype]。ToString（）;
dr [QTY] = reader1 [qty]。ToString（）;
dr [RATE] = reader1 [price]。ToString（）;
博士[AMOUNT（Rs）] = reader1 [amount]。ToString（）;
dt.DefaultView.Sort =VEHICLE NO;
dt.Rows.Add（dr）;
if（preVno == afterno）
{
IsSubTotalRowNeedToAdd = true;
}
else
{
IsSubTotalRowNeedToAdd = false;
}
preVno = afterno;
}
if（IsSubTotalRowNeedToAdd == true）
{
dt.Rows.Add（nr）;
prevtot = prevtot + Double.Parse（amt）;
nr [0] = prevtot;
}
else
{
nr [0] = 0;
prevtot = 0;
}
//}
GridView1.DataSource = reader1;
GridView1.DataBind（ ）;
reader1.Close（）;
这就是我在这段代码中从数据库中检索数据的方法顶部位置我想在同一个车辆下面换新行，所以请帮我搞定....

{
IsSubTotalRowNeedToAdd = false;
}
preVno = afterno;
}
if (IsSubTotalRowNeedToAdd == true)
{
dt.Rows.Add(nr);
prevtot = prevtot + Double.Parse(amt);
nr[0] = prevtot;
