button's OnClick event runs after page databinding...a GridView control iterates users in my database and below it there are
search fields and Search button which applies filter expression to the SqlDataSource. The GridView is manually databound in the Page_Load event and I also persist this databinding since the GridView uses postback since it users paging and sorting options. Now, if the Search button is used, it's OnClick event is run *AFTER* the Page_Load event so if I use it, I am actually databinding twice! Is there some way for me to check in the Page_Load if the Search button was used or how can I handle this situation? Databind during the page_load only if not Page.IsPostBack.

restore the control's state (and that of its rows) on postback without the need to databind. Are you saying that paging/sorting is somehow interfering with that process for you?
