I'm trying to so something really basic, but seem to be having trouble. I have a functioning page, but I wanted all the pages on the site to have PrintToPDF functionality. It semed pretty simple, just move the control to the Site.Master page (this is an out of the box ASP.NET WebForms project with Visual Studio 2017. When I call the method, I get a page with the error: One page can only have one ASPXToPDF control. (pasted below).
When I examine the Page Source,I don't see any evidence of two instances. Sure this is a newbie question, but I'm at a loss.

Hi, We do not see any obvious problems based on what you provided. What you can try to do is to create a small separate project with the same master page structure and see if it works for you. If that works, then you can compare the two projects to see if you can find out what triggered the problem. Usually as soon as you find out what triggered the problem, it will make sense to you. If you have reduced the test project to a minimum but the problem still occurs, you can send the test project to us and we will be happy to take a look. See here for more details on how to send the test project to us: https://www.essentialobjects.com/forum/test_project.aspxThanks!

Thanks. It was a newbie mistake and I figured it out ten minutes later but couldn't cancel the post.
If you don't mind an unrelated question, what's the best way to pass information from the Page_Load method to the asynchronous AfterRender event? I can think of several ways to do it, but wonder if there is a best practice.
Thanks

Hi,
We are not expert on this so we usually do not provide any advice on such questions. I believe you will be able to get more extensive and complete information on this if you search online.
Thanks!
