Error: AjaxControlToolkit is not defined on page refresh

Hi Kbflame,

I was failed to reproduce your issue with your sample code, so I suspect that your problem is mainly caused by the Ajax Control Toolkit's version. My Version is V10618. If yours is lower than mine, please upgrade it and have a test.Thanks

Best regards,

Jonathan

Hi Jonathan, my version is v10920, which is the latest one. Did you try it on firefox?

Whan happen is when after you click the button and reload the page, you'll see the CollapsiblePanelExtender is not working. If you open the error console from Tools menu, you can see the error message (AjaxControlToolkit is not defined). Thank you.

Hi Kbflame,

I have reproduced issue on Firefox. In my personal opnion, it is a browser behavoir related issue. The easiest way to resolve this issue is add hidden div to the end of the page and add another CollapsiblePanelExtender inside the Div. For example,

<Div style="display:none">CollapsiblePanelExtender</div>

We also suggest that you should post it toCodePlex to notice the developers who are taking responsibility to Ajax Control Toolkit. Thanks.

Best regards,

Jonathan.
