前台页面的Repeater控件绑定后台页面的方法

<asp:Repeater ID="rpGoods" runat="server">
                <ItemTemplate>
                    <div class="goodsInfo">
                        <h3><%# GetGoodsName(Eval("goodsname").ToString())%></h3>
                        <span style="color:Red;">￥<%#Eval("goodsprice") %></span>
                        <p><img src='<%# "img/goods/"+Eval("goodsimgpath") %>' alt="" /></p>
                        <p>
                            <asp:Button ID="btbBuy" runat="server" Text="购买" />
                        </p>
                        

                    </div>
                </ItemTemplate>
            </asp:Repeater>
         
其中GetGoodsName()是后台页面中的一个方法名，需要传递一个string类型的参数
