The code where i call the page is this:
And in the activate event of the page i want to show is this:
If i ignore the error the program works fine. The error is shown every time i activate the page...Do i need to initialize the control is some particular way ?
You have to annotate that in this way i do nothing on the pdf control because where i set the pdf file is in the commented line of the method. If i uncomment the line i have the same error.
Thanks
