How to create XPS file silently?

Question

I have UIElement(Grid) with many components on it. I want to save it as XPS document but without seeing any popup windows like SaveDialog Window.
How to do that?

I have for now something like this:

System.Printing.PrintQueue queue; //as "Microsoft XPS Document Writer"
System.Windows.Xps.XpsDocumentWriter writer = 
       PrintQueue.CreateXpsDocumentWriter(queue);
writer.Write(myUielement);

Answer 1

You can write any UI element directly to an XPS document without using the "print" functionality. Use the XpsDocument and XpsDocumentWriter classes as dictated here.
