How to switch off viewport border in plot?

[bobjiang.au]

I am using c# to control viewport and plot, but the viewport border is always printed out. Maybe I can get the border object and put it to a not-to-print layer.......now the question is how to get the border object?

Thank you in advance for the help!

You should be able to place the Viewport on a non-printing layer. You get the viewports for a layout from the Layout.GetViewports() method.
