I had a problem doing something similar; cleaning a form to remove unwanted
items that asp.net kindly drops in there.

I noticed that .net didn't seem to have a HTML form data collection object,
in terms of something that can be posted between pages; the HtmlForm being
something else. However the form could be sent to another page (or I guess
to a method within the same page) and the parameter collected there as a
NameValueCollection and you can iterate the NameValueCollection to copy the
items you want to a different NameValueCollection. You just can't remove
items because they are read only. Exactly what paypal will make of a
NameValueCollection sent to it in lieu of a form I don't know.

Problem with that is at the end of the day you have a NameValueCollection
left and this is NOT the same as a Form collection; it just has the same
data in it. A HTML form object collection is derived from
NameValueCollection.

But, doesn't .NET 3.5 now allow one to use several forms on a page?

Also, if you send one of those huge asp.net forms why should paypal mind,
provided that you send all the data that paypal wants? I can't see why there
should be a problem with asp.net sending too much data.

The best place to ask these questions is http://forums.asp.net/ You problem
is quite specific but I'm pretty sure there'll be someone there who has
solved the exact same problem.
