[Mono-dev] ASP:UpdatePanel with UpdateMode="Conditional" updates always

Wed Aug 19 09:54:26 EDT 2009

Hi,

I'm facing such a problem:

ASP:UpdatePanel with UpdateMode="Conditional" updates always, though no
child
controls caused postback, and no triggers were defined.
The are two UpdatePanels on a form. The child control of one UpdatePanel
causes
postback, that's why only this panel should be updated. On windows it works
fine. But with mono both panels are updated.

Here is my page:

<%@ Page Language="C#" AutoEventWireup="true" Codebehind="Default.aspx.cs"
EnableEventValidation="false"
    Inherits="MONO_Ajax_Test._Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
    <script src="js/jquery.js" type="text/javascript"></script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        &nbsp;</div>
    <asp:ScriptManager ID="MainScriptManager" runat="server"
EnablePageMethods="true">
    </asp:ScriptManager>
    <script language="javascript" type="text/javascript">  	
    	$(document).ready(function() {
    		ref = setInterval('UpdPanelUpdate()', 4000);
    	});
    </script>

    <script type="text/javascript">
    	function UpdPanelUpdate() {
    		var button = document.getElementById("<%= button.ClientID %>");
    		button.click();
    	}
	</script>

        <table>
            <tr>
                <td style="height: 206px" valign="top">
                    <asp:UpdatePanel ID="InsertEmployeeUpdatePanel"
runat="server" UpdateMode="Conditional">
                        <ContentTemplate>
                          <asp:Label runat="server"
ID="InputTimeLabel"><%=DateTime.Now %></asp:Label>
                        </ContentTemplate>
                    </asp:UpdatePanel>
                </td>
                <td style="height: 206px" valign="top">
                    <asp:UpdatePanel ID="EmployeesUpdatePanel"
runat="server" UpdateMode="Conditional">
                        <ContentTemplate>
                            <asp:Label runat="server"
ID="ListTimeLabel"><%=DateTime.Now %></asp:Label>
                            <asp:Button ID="button" runat="server" 
OnClick="button_Click" style="display:none;"/>
                        </ContentTemplate>
                    </asp:UpdatePanel>
                </td>
            </tr>
        </table>
    </form>
</body>
</html>

and Code Behind:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Collections.Generic;

namespace MONO_Ajax_Test
{
    public partial class _Default : System.Web.UI.Page
    {

        protected void Page_Load(object sender, EventArgs e)
        {
        }

        protected void button_Click(object sender, EventArgs e)
        {
        }
    }
}

What can cause such a problem?
