I just followed the Joe Stager to implement AutoComplete Extneder on some of my pages.  Just wondering instead of returning one column of data from the web service, is it possible to return more columns i.e. customer name and customer ID?  Thanks for any reply. 

Just found it reported in CodePlex issue tracker under id# 9043.  Hopefully it'll be available in next release.

Hi,

 I wrote a patch for the same issue over on CodePlex.

I discuss how to use it here :

Hope this helps
