Have a close look on javascript error see which object is not found . Try to work out the object javascript is expecting is passed properly or not.

even i face such errors and these are generally not submitted

if you are using document.forms[1] .element try making it document.forms[0]

I hope this helps

I found the solution. The panel control can't have Visible property setted when you use Ajax. I remove all this settings and all work fine.

[]'s
Were you able to hide the panels that you didn't want visible, still using Atlas?

hello.

well, to hide things you don't really need atlas. just use on of the css style properties available (ex.: display, visible, etc)

Agreed, but programmatically it would seem logical to use .NET methods, instead of changing CSS styles. No?

hello.

well, if you're just hiding then i think that there's no need to incur in a server call to do that...
