I am looking to improve the error logging of a web application using C# WebForms. I want to save a screenshot of what the page looked like just before the error was thrown (including what users had in the input fields). Everything I have found was just getting a copy of the page without the user input.

Thanks

Well , in a webform application the application it self run on the user computer/phone/tablet (usually a browser) so you cant really have access to the GUI of the user.

You got 2 options :

1.Force the user to install some sort of logging application on his device which will generate screen shots (not likely to happen), or just send you a screenshot with the bug report.

2.Log Log log Log every error the a database/file or what ever with as many info you can. We usually log the URL , Exception type + message , stack trace , user info , date time

Normally this is enough for us.
