Hi,
Using your demo page I cannot see any ViewState size. Is the component still working?
Hey sorry about the delayed answer, was out for the weekend.Yes Leonardo Fernandes is right, my personal went asleep once and i didn't notice that when i got it back up, the site property went into default value again.Fixed.
The component only works after a site property ShowCompressedViewstate is set to True. Presumably, the author didn't toggle this flag, and that's why the demo page appears blank.
However, the component still works, so you can download it and publish on your environment. Just remember to change that site property.
