Есть WPF приложение, в одном из окон есть контрол DocumentViewer, в котором отображается сгенерированный отчет.
Для печати вызываю подобный код:
1.

private void PrintSelectedReportExecute()
{
var printDialog = new PrintDialog();
bool? printDialogResult = printDialog.ShowDialog();
if (printDialogResult != null && (bool)printDialogResult)
printDialog.PrintDocument(printPreviewWindowViewModel.Document.DocumentPaginator, "NameOfReport");
}
Открывается диалог печати из которого уже пользователь отправляет на нужный принтер печать отчета.
Все работает ормально. Единственное в чем возникла необходимость это сделать так что, окно диалога печати (printDialog)
было окном поверх всех окон (Topmost = true).

Т.е. это просто класс, где-то внутри себе создаюший окно, но насколько я понял не возвращаюший ссылку непосредственно на окно.
Как сделать так чтоб окно диалога печати (PrintDialog) было окном поверх всех окон (Topmost = true)?
