the http reponse to file? ASP.NET 2.0

I want to generate a pdf file of "the current page".

It is a ASP.NET aspx file created partly from GET parameters, but most often
using the ASP.NET event model (i.e. clicking buttons etc).

One of the buttons is called "Generate a pdf document of the current page"
and it clicking it should create a pdf document on the server side and
returning the pdf to the user.

To my aid I have a server side component that can convert a file or the html
content of a URL to a pdf document. So if I somehow can generate the
information of the current aspx page to file, I can convert it to pdf and
change the Response.ContentType to "application/pdf".

But the question is how to generate the file that I want to convert. If I
send the current URL to the pdf component, it will point to the page and how
it looks when no interaction has been done. What I really want is the page
after all clicks, i.e. how it looks "right now".

Any ideas? Thank you,

HttpResponse allows you set another stream as a filter using HttpResponse.Filter.
You could use that to write the response to a temporary file, create the
PDF, and write the PDF back to the actual response stream.

Very interesting!

It seems the file isn't created until the Response ends. This seems natural
to me when thinking about it.

But when the response has ended, I per definition have lost my chance to
alter the response (remeber, I wamt to send the pdf instead). I guess I will
have to trigger another request somehow, and in the new Response show the pdf.

Havn't still figured out the last details yet. Thanks, anyhow, for your kind
help.

Regards

Are you sure you just don't need a Response.Flush()?
