卖个关子! 答案明天揭晓! 不要骂我!
其实很简单,在 ASPX 的 HTML 里可以访问到:
<%@ Page language="c#" Codebehind="WebForm1.aspx.cs" AutoEventWireup="true" Inherits="WebApplication1.WebForm1" %>
<%@ Register TagPrefix="uc1" TagName="WebUserControl1" Src="WebUserControl1.ascx" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
<HEAD>
<title>WebForm1</title>
<meta name="GENERATOR" Content="Microsoft Visual Studio .NET 7.1">
<meta name="CODE_LANGUAGE" Content="C#">
<meta name="vs_defaultClientScript" content="JavaScript">
<meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5">

<body MS_POSITIONING="GridLayout">
<form id="Form1" method="post" runat="server">
<uc1:WebUserControl1 id="WebUserControl11" runat="server"></uc1:WebUserControl1>
<script language="C#" runat="server">
void Page_Load(object sender, EventArgs e)
{
Response.Write("HTML");
this.WebUserControl11.TextBox1.Text = "HTML";
//调用在 Codebehind 里声明的 foo 方法将 WebUserControl 传到 Codebehind
this.foo(WebUserControl11);
}
</script>
</form>
</body>
</HTML>
