title: How to handle PostBack inside ASP.net Custom Control
body: <p>May be I am missing something important in order to implement CustomControl properly as per requirement or having a lack of knowledge. Actually I have Created CustomControl (.dll)for searching purpose having 3 Dropdown boxes(populating from database), 1 textbox and search button, after choosing appropriate filter criteria user clicks on Search button and simple gridview appears. My problem is I dont want to fill dropdown boxes in CustomControl on every post back(fired from page).</p>
