Additionally, you can also customize the Print Preview dialog in GanttView applications by using the the PreviewHelper property of the PrintInfo class. For instance, if you do not want to show the Open button in the Print Preview Dialog of GanttView application, you can simply set the visibility of that button to false. Other than this, you can also set the visibility at design time via the Properties window.

Below code snippet shows how you can set the visibility of the button to false.

{
      if (c1GanttView1.PrintInfo.PreviewHelper.C1PrintPreviewDialog is C1.Win.RibbonPreview.C1RibbonPreviewDialog)
                (c1GanttView1.PrintInfo.PreviewHelper.C1PrintPreviewDialog as     C1.Win.RibbonPreview.C1RibbonPreviewDialog).RibbonElements.FileOpen.Visible = false;
