RequiredFieldValidator - on-the-fly changes

You can use client-side API to enable it at client but as you set
Enabled=false at the server, you'd need to set it back at the server as well
(for server-side validation to work)

See this article for info about validator API:

I disable a RequiredFieldValidator (.Enabled=false) in Page_Load (WebForm
with C#). How can I enable the RequiredFieldValidator when I click a button
(e.g., in its event handler). I don't wan't to use validation until just
before I'm ready to leave the form. At present, my
RequiredFieldValidator.Enabled=true code requires that I click the exit
button twice before this enable takes effect. That's one too many times.
