@Dave:

Ahhh, now it makes sense. I'm wondering why I couldn't find more on this. Do you have a link to explain the difference between the methods?

No. ClientScript apis were around before UpdatePanel existed. UpdatePanel was introduced as a separate download from ASP.NET, and it needed the additional Control parameter, so ClientScript is now a legacy API.

@Dave:

Yes, the controls were being loaded into an UpdatePanel. Isn't the ClientScript's method supposed to do the same thing?

Is it within an UpdatePanel? The ScriptManager version is required to be compatible with it. Basically, it allows UpdatePanel to know which control needs which resources, so only the controls within it can register new items on the page, even though the entire page is loading as usual.

Interesting ... Do you know how this fares in a web farm?

I'm not sure what the problem might be, but if you're just trying to keep the viewstate off the page, you might also want look into the SessionStatePagePersister:

msdn.microsoft.com/.../system.web.ui.sessionpagestatepersister.aspx

I've been using this for a long time and it works great. It doesn't even chew up memory usage on ther server that badly because it only keeps the previous 9 viewstates (pers user obviously) at any given time. As long as you don't hit the back button more than 9 times, you're fine. You can also up the setting in the web.config. Hope that helps!
