Page Load event is raised before postback values are processed.

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

use an private variable to hold "clicked" state and perform final operations on OnPreRender – ertan Sep 20 '12 at 18:24
private bool editClick = false; private cmd_Edit_Click(object sender,..) { editClick = true; } private Page_OnPreRender(object sender, ..) { if (editClick) { FillData() } ); sorry for lack of space. – ertan Sep 20 '12 at 18:41

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.
