Can someone help me.

 I'm try to use Accordion Control from AJAX Control Toolkit but I have problem in Design time .... it is working fine wehn I run the application but in Design time I'm getting this error:

Error Creating Control - MyAccordion

'Panes' could not be initialized. Details: 'Panes' could not be added to the collection. Details: Object does not match target type.

If someone knows how I can fix this error please tell me ...

Thanks in advance.

I have the same problem.  I develloped a user control a month ago and it was working fine.  Today I wanted to continue my devellopement and when I opened my control in design view it is now giving me the error.  What is that about?    And when I run my application it's seems fine. Todor did you manage to fix your problem? 

 Thanks

I have had a lot of prolems with the Accordion control. Mainly because the panes kept disappearing every time, I did any work on the control in Design View. However, working with the control in Source View seems to be pretty easy, once you get the hang of it. I watched a video by Joe Stagner and that video taught me how to work with the control in Source View only. After that, I haven't had any problems with it.

I strongly suggest that you check out the video if you haven't already. You'll find it at http://www.asp.net/learn/videos/view.aspx?tabid=63&id=87 -- I hope it works for you.

if i close the entire application and open again then my problem will be solved,then i view the accordion in design view also

with regards,

Hi,

<cc1:Accordion ID="Accordion1" runat="server" FadeTransitions=true>

add FadeTransitions=true.
