repater列求和

repater：

sql里面求和

 1 public void showList()
 2         {
 3             string fromdate = txtFromDate.Text;
 4             string todate = txtToDate.Text;
 5             string sales = ddlSales.SelectedValue;
 6             DataTable dt = B_Commission.getSales_volume(fromdate,todate,sales);
 7             rptList_stk.DataSource =dt;
 8             rptList_stk.DataBind();
 9 
10             if (dt != null && dt.Rows.Count > 0)
11             {
12                 foreach (DataRow dr in dt.Rows)
13                 {
14                     p_sub_total = p_sub_total + dr["amount"].getDbl();
15                     P_sub_profit = P_sub_profit + dr["profit"].getDbl();
16                 }
17             }
18 
19             lbl_Total.Text = MyNumber.showNum_TwoDecimal(p_sub_total);
20             lbl_Total_profit.Text = MyNumber.showNum_TwoDecimal(P_sub_profit);
21         }

if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
{
Model.MP_invoiceItem mp = ((Model.MP_invoiceItem)e.Item.DataItem);(使用model转化的时候)
tal = tal + Convert.ToDecimal(mp.amount);
}
if (e.Item.ItemType == ListItemType.Footer)
{
Label lbl = (Label)e.Item.FindControl("lbl_Total");
lbl.Text = tal.getString();
}

Model.MP_invoiceItem mp = ((Model.MP_invoiceItem)e.Item.DataItem);
Label lbl = (Label)e.Item.FindControl("lbl_Total");
lbl.Text = mp.amount.getString();
tal = tal + Convert.ToDecimal(mp["amount"]);

repeater增删改

 1 获得linkbutton的CommandArgument的值
 2 int spec_id = e.CommandArgument.getInt();
 3 
 4 if (e.CommandName == "Edit")
 5             {
 6                 textcommand = int.Parse(e.CommandArgument.ToString());

41 
42             ShowItemspec();
