ASP.NET AJAX CascadingDropDown

Is there any way to use the ASP.NET AJAX CascadingDropDown controls WITHOUT setting EnableEventValidation to false?  I've searched exhaustively, but haven't found anything.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I am afraid there is no way because the content of the dropdown control is altered by the extender at clientside. From the perspective of the server, the content of the dropdown is different after postback.  Hence the builtin security mechanism of ASP.NET returns error.  It seems the only way is to disable the error check mechanism (i.e. disable EnableEventValidation).
