Hi there!

I've builded a small sample to demonstrate the issue I've found.

From a page, you click on a button to show a report, which is on another page (it has only the viewer and a back button).
You clik back and return to the previous page. Then you click again the button to show the report. App crashes with the message

"A method was called at an unexpected time.\r\n\r\nOnly one handler for the PrintTaskRequested event may be registered at a time."

Best regards

Hello.

Sorry, but we couldn't find any sample.

Thank you.

Hi!

Sorry, my mistake!

Here it goes!

Hello.

When you click on the back button you should call Dispose() method, then there will be no error. Thank you.

Hello Aleksey!

It worked, thank you!
