Accordian ajax control gives JScript runtime error

Question

I\'m using Accordian control of ajax toolkit.

I\'m getting the following error:

Microsoft JScript runtime error: Sys.ArgumentException: Value must

Answer 1

There could be a whole host of problems associated with this error. Not much to go on, but here are some possibilities

1. Check the visibility settings of the Accordion. Apparently if it is set to visible=false or style="display:none" it may not hook to the extender correctly.
2. Also check for any commented out Accordion controls (i.e. comment blocks). This may cause the ScriptManager to look for an Accordion that is not there.
3. Finally, in case it is not the Accordion throwing the error, make sure each control and its extender are in the same UpdatePanel.

Hope this helps!
