Dropdownlist State??

[Curt Emich]

Is there a better way in .NET to preserve the state of say, a dropdown list
other than using hidden fields and the like? I've noticed that the method
"SelectedIndexChanged" of a dropdown list is only called when "Autopostback"
is true. This seems to defeat the purpose altogether.

When I change the value in a dropdown listbox, I want to know what the
ORIGINAL value was so that I can PRESERVE that value when the page is
re-rendered. As it stands, I don't see any method that is fired BEFORE
postback that would allow me to store the original value of the listbox.

Do I just go back to good old fashioned javascript?

If the user is seeing the dropdown for the first time, then the value is the
default value. If this is a prepopulated form based on some choices the
user made earlier, well then the /original/ value would be stored in a
database or XML file or whatever you are using to store information.

If you are thinking of returning to JavaScript
take a look at DecisionScript at www.VanguardSW.com
No more stateless worries - DecisionScript takes care of that for you.
