将评估值传递给购物车的C#方法

我正在为我的班级创建一个购物车web应用程序。当用户单击

添加到购物车

按钮时，我想将每个特定产品的

ID

值传递给代码隐藏中的一个单独方法。不确定我的语法是关闭的还是无法正常工作。这是我的分数：

<asp:Button ID="AddToCart" CommandName="Add" 
OnClientClick ='<%# ListView1_AddToCart(Eval("ID"))%>'
CssClass ="Button" runat="server" Text="Add to Cart" />

我不断遇到各种问题，但这给了我以下错误：

The best overloaded method match for 'OurCats_GrumpyCats.ListView1_AddToCart(string)'
has some invalid arguments.

我如何解决这个问题？还有更好的办法吗

编辑：这是我的分数

尝试下面的代码

<asp:Button ID="AddToCart" CommandName="Add" 
OnClientClick ='<%# ListView1_AddToCart((string)Eval("ID"))%>'
CssClass ="Button" runat="server" Text="Add to Cart" />

OnClientClick=''

按钮是否适用于每一行记录？能否显示您的标记？“每个产品的ID”来自何处？您是否使用某种中继器控件来显示数据？是的，按钮适用于每一行。

<asp:Button ID="AddToCart" CommandName="Add" 
OnClientClick ='<%# ListView1_AddToCart((string)Eval("ID"))%>'
CssClass ="Button" runat="server" Text="Add to Cart" />

OnClientClick ='<%# "ListView1_AddToCart(" +Eval("ID") + " );" %>'
