Answer 1

Page Load event is raised before postback values are processed.

Try to call "FillData" on OnPreRender event to prevent from this.

First, have you checked the actual name of your hidden field on the page? Asp .net likes to change them from what you think they are, so the name will probably be different for javascript. Also, try document.getElementById('whatever_the_id_is').value = document.getElementById('your_span').innerHTML; which uses IDs instead of names.
