- Spot on for what i need
- Aaron Gibbs
- Simply reads the size of the first __Viewstate hidden form field. If you are using viewstate chunking this is worthless.
- Marc de Vries
- Je weet meteen hoeveel procent van je pagina uit ViewState bestaat. Snel en simpel!

- כל כך פשוט, קל ונח.
- John Cockrell
- Needed to refresh initially to get information to show, after that worked well. Requires access to full page which is guess is unavoidable.
