[Mono-dev] ask for backport on mono 1.2.5 branch

Fri Aug 31 09:48:58 EDT 2007

In the actual release, a simple ASP.NET with a ListBox Control don't
work, viewstate deserialization problem...

This problem as been fixed in the trunk by :

2007-08-30 Igor Zelmanovich <igorz at mainsoft.com>

        * ListControl.cs: fixed selected items state management.

Could this be backported to the mono 1.2.5 branch?

Here's a test case for this problem :

Default.aspx:
<%@ Page Language="C#" Inherits="TestViewState.Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head>
	<title>Default</title>
</head>
<body>
	<form id="form1" runat="server">
		<asp:Button id="button1" runat="server" /> 
		<asp:ListBox id="drpSociete" runat="server" CssClass="TextBox200"
Width="200px" Visible="True"
            Rows="1"></asp:ListBox>
	</form>
</body>
</html>

Default.aspx.cs :
// Default.aspx.cs created with MonoDevelop
// User: hubert at 15:02 31/08/2007
//
// To change standard headers go to Edit->Preferences->Coding->Standard
Headers
//

using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;

namespace TestViewState
{

	public class Default : Page
	{
		protected ListBox drpSociete;

		protected override void OnLoad(EventArgs e)
		{
			if (!IsPostBack){
				drpSociete.Items.Add("bouh");
				drpSociete.Items.Add("bah");
			}
		}

	}
}

Click two times on the button and you'll obtain :
Server Error in '/' Application
