Problem with Page setup Dialog

Question

Hello all,

I'm using PageSetupDialog to set paper size programatically for printing purpose.

When I select 16K as paper size, it will set it. But if I close that dialog & again open it, instead of showing 16K as selected PaperSize, default paperSize gets selected. For other sizes, it works fine.

Is there any other setting that i need to do for paperSize as 16K(since it is treated as Custom paper size, I tried to set PaperKind but since it's readOnly property couldn't help)?

Thanks
