I have a use case which requires me to record data whenever a report is printed. In pursuit of this, I am trying to replace the build in Print() tool and replace it with my own.

I have read this documentation which shows how to remove and reorder the buttons well enough, but it does not support adding a new tool all-together. Javascript event listeners will not work for me because ultimately what I want to do is accomplish a database write, which would be insecure through javascript.

 I have been able to establish a workaround by following this documentation and creating a button *outside* of the ReportViewer, however, I would still like to find a way to put the button inside of the ReportViewer toolbar if possible.
