Question with pagesettings

Hello
We used PrintSetupDialog controller,
But it show a error message 'about right is -1'

why?
sample:
PrintSetupDialog dlgPrintSetup =
new PrintSetupDialog();
dlgPrintSetup.PageSettings = mainDiagram.View.PageSettings;
//mainDiagram is Diagram controller.

Hi LX,

We regret for the inconvenience caused. I have tested this issue in v.5.1.0.51. I am afraid, I was not able to reproduce this issue in our Printing sample.

Could you please check the sample and let me know whether you are able to reproduce the issue in this sample?. It would be helpful if you provide a sample or modify the Printing sample to reproduce this issue. It will help us to resolve it as early as possible.

Thanks for using Essential Diagram.
