RE: [Mono-dev] Controls in HTML comment block behave different in .Net and Mono

Mon, 06 Feb 2006 00:14:47 -0800 

The "Src" directive won't work for me. I get compilation errors under both Mono 
and .Net (attached).

You may have fallen foul of the same thing I did:


Codebehind="WebForm1.aspx.cs"


is a Visual Studio thing, apparently.  You want to replace "CodeBehind" with 
"Src".

It worked for me, anyway.

Cheers

Hi,

When I have an ASP.Net control in an HTML comment block of an aspx page it does 
not compile under Mono but it does compile under .Net.

Exmple aspx:

<%@ Page language="c#" Codebehind="WebForm1.aspx.cs" AutoEventWireup="false" 
Inherits="MonoCharsetTest.WebForm1" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
        <HEAD>
                <title>WebForm1</title>
                <meta name="GENERATOR" Content="Microsoft Visual Studio 7.0">
                <meta name="CODE_LANGUAGE" Content="C#">
                <meta name="vs_defaultClientScript" content="JavaScript">
                <meta name="vs_targetSchema" 
content="http://schemas.microsoft.com/intellisense/ie5";>
                <meta name="Content-Type" content="text/html; charset=utf-8">
        </HEAD>
        <body>
                <form id="Form1" method="post" runat="server">
                        <!--
                        <INPUT id="Button1" type="button" value="Button" 
name="Button1" runat="server">
                        -->
                </form>
        </body>
</HTML>

Example cs:

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

namespace MonoCharsetTest
{
        /// <summary>
        /// Summary description for WebForm1.
        /// </summary>
        public class WebForm1 : System.Web.UI.Page
        {
                protected System.Web.UI.HtmlControls.HtmlInputButton Button1;
        
                private void Page_Load(object sender, System.EventArgs e)
                {
                        // Put user code to initialize the page here
                        Button1.Value="Hello";
                }

                #region Web Form Designer generated code
                override protected void OnInit(EventArgs e)
                {
                        //
                        // CODEGEN: This call is required by the ASP.NET Web 
Form Designer.
                        //
                        InitializeComponent();
                        base.OnInit(e);
                }
                
                /// <summary>
                /// Required method for Designer support - do not modify
                /// the contents of this method with the code editor.
                /// </summary>
                private void InitializeComponent()
                {    
                        this.Load += new System.EventHandler(this.Page_Load);

                }
                #endregion

        }
}

Results when running on mono: 

Server error in '/c' application

--------------------------------------------------------------------------------

With .Net I get a page without the button and no compilation error.

Wich is the right behaviour?
VS.Net project, Mono and .Net results are attached.

Thanks!
