title: How to fire dropdownlist's SelectedIndexChanged without postback?
body: <p>I've got a DropDownList on my page databound to a query from my database (Databinding is set up only in my .aspx file, not in codebehind). Next to it I have a second DDL that gets populated from the SelectedIndexChanged function of the first one. This works, but only when AutoPostback is set to true. </p>
  
  <p>Is there a way to fire the SelectedIndexChanged event or manually call this function in my codebehind without having to reload the page every time?</p>
