chechbox OnCheckChanged doesn't work!

[Vittorix]

Hi all,

Here's a matter I can't fix:
the method OnCheckedChange d is correctly fired when the checkbox is
selectioned, but not when the checkbox is deselectioned! (the page just
reloads)
Please help, thanks in advance.

I've an Ajax Accordion and a Repeater inside, both connected with a
database.
here is the fundamental structure:
=============== =======aspx page=========== =============== ==============
<%@ Page Language="C#" AutoEventWireup ="true" CodeFile="Shipp ing.aspx.cs"
Inherits="test" MaintainScrollP ositionOnPostba ck="true" %>


<ajaxToolkit:To olkitScriptMana ger EnablePartialRe ndering="true"
runat="Server" ID="ToolkitScri ptManager1" />

<ajaxToolkit:Ac cordion ID="MyAccordion " runat="server"

Re: chechbox OnCheckChanged doesn't work!

From docs.
A CheckBox control must persist some values between posts to the server for
this event to work correctly. Be sure that view state is enabled for this
control.

The CheckedChanged event is raised when the value of the Checked property
changes between posts to the server. This event does not post the page back
to the server unless the AutoPostBack property is set to true.

Occurs when the value of the Checked property changes between posts to the
server.

tried with AutoPostBack="t rue" and EnableViewState ="true", the event is
triggered but when I select it is triggered with a wrong ClientID!
this is the problem
