I used accordion control and removed the click event on load using the $removedHandler in javascript but I've got an error "Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method."
Is there a way to validate if the event handler is already removed? Here's my sample code:
I run into this problem while playing with accordion for a project. Sometimes VS 2008 auto generates code, without me wanting to!!!. Less generally I have an Accordion with 2 Accordion Panes in it. When modifing properties of the Accordion VS 2008 adds an Accordion extender and duplicates the two Accordion Panes!

I have a override Render method on my AccordionMenu.ascx.cs, basically just replace the <span></span> tag with <div></div> due to w3c compliance requirement, this is the c# code:
[Code]....
but when i try to run it, the page always throws an exception to me like this: Extender control 'MyAccordion_AccordionExtender' is not a registered extender control. Extender controls must be registered using RegisterExtenderControl() before calling. this is the context of my pages: accordion menu is placed in the content page, and the content page is inherited from a master page, the master page has a script manager.
I am having 2 problems at this time with the ajax accordion extender. At my website [URL] I have an accordion extender for the "Products" button. When I browse my site in IE everything is as it should be. You click on the "Products" button and the accordion expands to show 4 more buttons. However if you browse the site in Chrome the accordion expands and you see an empty pane. I have tried changing many settings in the accordion control and pane but nothing seems to make it work correctly in Chrome.
Another problem I am having is I would like to make the accordion expand when you hover your mouse over the "Products" button. The functionality I want is that it will stay open until you either hover over any other button outside of the accordion, back over the "Products" button again or you navigate to a new page. Here is the code for the troubled accordion pane:

I want to create an accordion inside a gridview with the following functionality:
The user will only see one field of the gridview initially, the ProductCategoryID. When the page loads it will only query the ProductCategoryID and this will be the only field displayed.
Next when the user clicks on the accordion to expand it inside the gridview I would like to query the database to get all Products that are part of the ProductCategory. I will query using the ProductCategoryID that is being displayed.
I need to do this for performance issues. The main thing I am looking for is how to query the database once the user expands a given ProductCategoryID.
but now I think of it one thing I need to know: when you bind an accordion to a dataset will it create one pane for each record returned? It might be better to put the gridview inside the accordion. I'm willing to do either, as long as it works

I m using ajax accordion control to display the information of my company branches. Now it always displays one pane at a time. But i want that it should not display any pane at a time. Only a single pane should be displayed when user click on header of that pane.
I followed a video tuturiol for the Ajax Accordion control and also created it manually using VWD2010ExpressAlthough the source code I downloaded works fine, mines dosen't. The links for the panes will not respond. Everything else seems to be ok.
