title: DropDownList in UpdatePanel
body: <p>In my project I have placed a dropdownlist in an updatepanel.what I wanted to do is to select a value from dropdownlist and use it in a session.</p>
  <p>but whatever I do, it will always give me null value because of not checking &quot;Enable AutoPostBack&quot;.and when I do this, it will refresh the page so this isn't what I wanted.</p>
