We would like to request that support for the printer tray selection be added to WPF.TextControl.<br /><br /> <br /><br /> Currently, in the WPF TextControl 23, the control can load a document containing the w:papersrc directive, but then silently discards it. There also is no interface available to set printer tray selection using the Page Setup dialog.<br /><br /> <br /><br /> As such, the request consists of making available a paper tray selection in the Page Setup dialog, as well as extend the API to allow for accessing the same (presumably in SectionFormat). See OpenXML PaperSource (w:paperSrc).
