Maybe it's simple, but I ask you: Did you use GridView in an UpdatePanel? And the Button saves a PDF File with Threading? Can a Timeout be a problem?

Solution 1

Print to a "PDF PRINT DRIVER".

Can be done client (by the client); or server side.

The resulting file can be "picked up" from wherever for whatever.
