Answer 1

You could use a LinkButton (or regular link) and have the url point to a handler (ASHX) that retrieves the data and sends back a response with content disposition set to attachment. Write the data to the response. You'll also need to set up some other headers in the response -- such as content type and length. This would give the document (file) a regular link that could perhaps be bookmarked (if a regular link) in the future so that it can be retrieved again. You'd need to pass enough data in the query string to be able to identify which data is to be downloaded.
