Hello guys,

I'm planning to create a cascading dropdown list of Country--> State/Province--->Zip code using geonames. Do you have any good web service or examples?

Your reply is greatly appreciated, Best

Here's a good example on creating cascade drop downs in MVC. From there you'd setup the web service calls to get what you want. You'll probably want to cache that data or provide a good singleton service to store it so you don't have the expense of multiple web service calls.

You want the user to select USA, get a list of the 50 states, select TX, and see a list of the 2,627 TX ZIP codes? Sounds awkward. There might be a better approach to solve whatever ultimate function you're trying to provide. Also see http://semaphorecorp.com/cgi/zip5.html
