FIRST: Correct my post from August...:
In the HTML output, ASP.net places its JS references just after the FORM tag. I needed some time until I realized that I have to place Marnix' code BELOW the JS references (this is: in the BODY BELOW the FORM tag), otherwise it can't override the ASP.net functions.

SECOND: Today I encountered a problem with Marnix' code and after some research found out that this code fails as soon as there's a custom validator (exactly: any validator without .controltovalidate) >> inputControl is Null >> can't assign a CSS class.

Luckily there's an easy solution: Add if (inputControl!=null) just before WebForm_RemoveClassName and WebForm_AppendToClassName.
Hope this helps to make a superb solution even better...

THIS is really smooth code! short and simple and does exactly what I want it to :) Thanx Marnix for this beauty!

In the HTML output, ASP.net places its JS references just after the \ tag. I needed some time until I realized that I have to place Marnix' code BELOW the JS references (this is: in the \ BELOW the \ tag), otherwise it can't override the ASP.net functions.

Thanks a ton for this code - short and sweet and does exactly what I needed!

Just a quick note: for some reason I couldn't get the code to work when I copy/pasted it. Not sure why, perhaps a character issue with the conversion. But, I just retyped what you had and it worked perfectly.

Thanks!! =D

But when I use it with AJAX, I am getting the following error.

"The State Information is Invalid for this page and might be corrupted."

Do you have any idea how we can avoid this?
