I have two list boxes on my form... lstCanSend and lstRecipients.. . well
then there are two buttons add and remove between them (your basic select
and pick listing) which uses java script to move the items between list
boxes (the listbox controls are server side ones with runat=server set on
them, the buttons are basic html button i dont want to post back each time
someone clicks on add or remove... that wastes time and bandwidth) well the
add and remove buttons work, but at postback there is no data returned from
the lstRecipients listbox, because when the items were added through java
script it did not get posted back to data (i only want to post back when
thet user clicks on the OK button which sends this data to a processor) here
is my html code with the java script inside it... where should i do the post
back of the lstRecipient data and how do i do it when the user clicks on the
OK button? thanks
