How, on client side, to dynamically change Downdownlist items.

[Q. John Chen]

I have two dropdownlist controls. ddlCountry and ddlState.
Say that ddlCountry has items United States and Canada, I want only
list US states if United States is selected and Canadian provices if
Canada.

It's simple to do it on the server but how can I do it ON CLIENT SIDE
with JavaScript.

In addition to ddlCountry and ddlStates prepare 2 hidden ddls: ddlUSStates
and ddlCanadianStates. On ddlCountry change copy options from the right
ddlXXStates to ddlStates.

You may want to investigate remote scripting.

The following example demonstrates dynamically filling secondary lists
based on a primary list selection.
