preload dropdown

[phil2phil]

hi,
had a question on preloading a dropdown. we have a textbox and
dropdown on the page, user is suppose to enter in a zip into textbox,
then the dropdown should load the state based on the zip. we can pull
the state from the database on a zip match table, but how do we preload
the dropdown, is there a way without posting back?

You need to use client-side code for this, not server-side, ergo, your
question would be best placed in a JScript, Javascript or VBScript
newsgroup.

As a little hint, do a search for MM_jumpMenu ;o)

You'll have to postback. This can be done without submitting your form by
using the XMLHTTP object. Google for that term to get an overview and some
examples of its use. Followup questions can be posted to a client-side
scripting newsgroup such as m.p.scripting.jscript

Don't know how it works exactly over there...

You could have the whole list (basically the first few numbers of the zip
and the corresponding state ?) rendered as a JavaScript array and select the
appropriate records when the zip code is entered... This way you won't have
a postback. It assumes the list is quite short...
