PrintDialog dlg = new PrintDialog();
Window currentMainWindow = Application.Current.MainWindow;
Application.Current.MainWindow = this;
if ((bool)dlg.ShowDialog().GetValueOrDefault())
{
     Application.Current.MainWindow = currentMainWindow; 
}

When I click on buton, the Print dialog is popped out. Here enter image description here But When clicking on print, nothing happenes, the dialog is just closing, and no results, it is not working not with Adobe PDF, not with ARX CoSign...

Solution

  • The rough working

        var printDoc = new PrintDocument()
    var dlg = new PrintDialog()

    If(dlg.ShowDialog() == DialogResult.OK)
    {
           printDoc.Document = [doc to print]
           printDoc.Setting = dlg.settings
           PrintDoc.print()
    }
