一个oncommand的问题

一个控件，文件名alphalinks.ascx，代码如下：

google_ad_width = 250; google_ad_height = 250; google_ad_format = "250x250_as"; google_color_url = "000000";

<%@ Control Language="C#" ClassName="Alphalinks1" AutoEventWireup="true" CodeBehind="alphalinks.ascx.cs" Inherits="MIS.controls.alphalinks" %>

<asp:Repeater ID="__theAlphalink" runat="server" OnItemDataBound="DisableSelectedLink" OnItemCommand="__theAlphalink_ItemCommand">

<ItemTemplate>

<asp:LinkButton ID="link"

runat="server"

CommandArgument="<%# DataBinder.Eval(Container, "DataItem")%>"

CommandName="Filter" OnCommand="Select" Text="<%# Container.DataItem %>">

</asp:LinkButton>

</ItemTemplate>

</asp:Repeater>

一运行这个控件，就出错说找不到Select的定义，可我在alphalinks.ascx.cs中十分明确的定义了函数

private void Select(object sender, CommandEventArgs e)
