简单响应DataList中的Button事件和Lable值

在<%@ Page Language="C#"...>上增加 enableEventValidation= "false " 这样子好像就没有那个回发或者或调无效参数无效的问题.

点击开Button 空间响应事件

 

  protected void bttPutToCart_Click(object sender, EventArgs e)
    {
            Button bt = sender as Button;
            int myIndex = ((DataListItem)bt.NamingContainer).ItemIndex;
            Label lblid = bt.FindControl("lblId") as Label;
            Label lbname = bt.FindControl("lblProduct_Name") as Label;
            Label lbprice = bt.FindControl("lblPrice") as Label;
            int id = int.Parse(lblid.Text);
            string name = lbname.Text;
            decimal price = decimal.Parse(lbprice.Text);
            Profile.shopcart.AddItem(id, name, price);
            Response.Redirect("../goods/Shop_car.aspx");
            Label4.Text = name;
       
           
    }
