I have asked this question on a number of forums and no one seems to know why this happens. <BR><BR>I have a form with 2 dropdownlists and a datagrid. On form_load I fill the first dropdownlist with "top categories" from an SQL DB. on autopostback it fires the selectedindexchanged event which fills the second dropdownlist with "sub categories" from the DB. On the 2nd droplist's autopostback it does a form post but the selectedindexchanged event for the second dropdownlist doesn't fire and the list resets to index 0.<BR><BR>Any suggestions?
