Exporting Search Results in ASP.Net GridView to Word Excel PDF CSV

I am trying to export a gridview that is returned from a search form.  The gridview also has paging enabled.  In order to export the records from all pages in the gridview I had to turn off paging and do a databind, but instead of only exporting the search results it exports all the records in the gridview.

How can I only export the records from the search results, but also the make sure the records on the different pages export also?

Thanks in advance.
