问题描述

你好



当用户想要在购物车中添加产品并点击添加到购物车链接按钮时，它首先显示选择尺寸以便我可以做什么它是


我的代码加入购物车：

hello

When user want to add product in cart and click on add to cart link button than it''s display select size first so how i can do it

my code for add to cart:

<asp:LinkButton ID="linkAddtocart" runat="server"  oncommand="BuyNow_Command"

               CommandArgument='<%#Eval("Product_ID") %>'>Add To Cart</asp:LinkButton>

protected void BuyNow_Command(object sender, CommandEventArgs e)
   {

       string str = "";
       if (Session["ProductID"] == null)
       {
           str = e.CommandArgument.ToString();
           Session["ProductID"] = str + "|";
       }
       else
       {
           str = Session["ProductID"].ToString();
           str = str + e.CommandArgument.ToString() + "|";
           Session["ProductID"] = str;
       }

       Label1.Text = str;

   }
