I found a lot tutorials out there showing you how to make one drop down list populates another one but most of them either render the second ddl html in javascript (dealing with DOM crap!) or use third-party controls such as ATLAS. Then I decided to come up with my own solution for the problem. What I did was wrap the regular ASP.NET drop down list with two strings and strip off the rendered html that is returned to the Ajax object. This provides me a lot of flexibility: One=> I can use the regular ASP.NET control not having to dealing with DOM objects in JavaScript. Two=> I can use the same technique to use any ASP.NET controls with Ajax.
