这是添加到购物车链接按钮的代码

Protected Sub GVAddToCart_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        If User.Identity.Name = "" Then
            MsgBox("You need to login first before adding anything to the cart!", , "")
            Response.Redirect("~/login.aspx", True)
            Exit Sub
        End If

        Dim sCart = New cart
        Dim itemName, GVPrice, offer As Label
        Dim userID, buyNo, itemID As String

        itemID = Request.QueryString("itemID")
        itemName = CType(ListView1.Items(0).FindControl("itemName"), Label)
        userID = User.Identity.Name

        Dim index As Integer = GridView1.EditIndex
        GVPrice = CType(GridView1.Rows(index).FindControl("price"), Label)
        GVPrice.Text = CType(GVPrice.Text, Integer)
        offer = CType(GridView1.Rows(index).FindControl("offer"), Label)

        If sCart.CheckIfItemPresent(userID, itemID, GVPrice.Text, offer.Text) = True Then
            Exit Sub
        End If

        buyNo = sCart.findLatestBuyNo(userID)
        Session("buyNo") = buyNo

        Session("buyNo") = sCart.AddToCart(itemID, itemName.Text, GVPrice.Text, offer.Text, buyNo, userID)
    End Sub

所以我想要做的是删除步骤1 ..我可以这样做吗？

如果我删除更多链接..它停止工作......请帮助我。

我必须点击更多链接才能获得添加到购物车链接...我想在一次点击中将项目添加到购物车..我现在拥有的...我需要两次点击。< / p>

当我点击更多时，它进入编辑模式..然后当我点击添加到购物车（在编辑模板中）..它从编辑模板中获取价格和提供值..如果我移动“添加到购物车“按钮进入ItemTemplate ...它无法访问优惠和价格值。如果我将“添加到购物车”按钮移动到ItemTemplate，我将如何知道正在点击哪一行？

根据您的描述“删除步骤1”，听起来您希望链接/按钮字段始终显示为“添加到购物车”。

建议创建ButtonField而不是ItemTemplates和EditItemTemplates。看来你不需要编辑功能，而只需要一种方法来访问行上的那些属性。

 <asp:GridView OnRowCommand="GridView_RowCommand">

     <asp:ButtonField buttontype="Link" 
                      commandname="Add" 
                      text="Add to Cart"/>

      <asp:BoundField datafield="itemName" headertext="Item"/>
      <asp:BoundField datafield="itemPrice" headertext="Your Price"/>
      <asp:BoundField datafield="shopName" headertext="Shop Name"/>
      ..... etc.

你的代码隐藏需要像这样改变：

  Sub GridView_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs)

    If e.CommandName = "Add" Then      
      Dim index As Integer = Convert.ToInt32(e.CommandArgument)
      Dim row As GridViewRow = GridView1.Rows(index)

      Dim itemName As String = Server.HtmlDecode(row.Cells(1).Text) 
      Dim itemPrice As String = Server.HtmlDecode(row.Cells(2).Text) 
      '...... etc
      'All required business logic to add to cart.
    End If

  End Sub

如何在我的GridView中单击链接？
