Yes, to switch language the client (ie. the browser) must request the server to
render the page in the new language. If the request to switch is from an
EventLink or ActionLink, then values entered into the form will be lost. That
is because they use HTTP GET. If your request to switch is from a Submit, then
values entered into the form will be sent to the server. That is because it
uses HTTP POST.
Remember that by default the server-side is stateless (and that is a good
thing). @Persist tells the server to keep state: it says keep a copy of the
last rendered value of something. (By default it keeps that copy in the
session, but there are options to keep it as a cookie, or in the URL, or
wherever you like).
If your user really does want to switch language while working in a form (which
is a very unusual use case) then try Submit with mode="cancel" or
mode="unconditional".
