How to get value in text field based on value from valuelist

[hardina09]

In my form, I am having Combo box, obviously values are provided by a valuelist-list of zip codes and textfield,

When user selects a particular zip code then based on zip code selected textfield automatcially get updated with city name corresponding to zip code.

Any suggestions, please reply

Surely an ondatachange method on the combo box would work to populate the found city value in the second field?

I presume this will be a restricted list of zip codes to enter, otherwise I would use a type-ahead text field as there are too many zip codes to make a good combo box. But as David says use the onDataChange event and then either with a query, 'find' or a relation populate the city field.
