how to update file ext pdf in gridview asp.net

Do you mean you want to change the extension of the PDF file in the Grid view?
Or are you trying to edit the data in the PDF file, and save it again to the database on the server side?

If you are trying to change the file name in the Grid view, you can find valuable information over web by searching for phrases like "how to customize Grid View in ASP.NET".

But if you are trying to edit the data of the PDF file, I know a programming toolkit (leadtools) that has HTML5 document viewing, updating and converting features over web. You can find online web application here:

If this is not what you want, please provide more details on your requirements so I may offer other possible solutions.
