Hello, Tra,
Thank you for writing.
Here is demonstrated a sample code snippet demonstrating how to create a custom
RadPdfViewer in order to hide the Headers/Footers tab in the
PdfPrintSettingsDialog:
public class CustomPdfView : RadPdfViewer
{
protected override RadPdfViewerElement CreateViewerElement()
{
return new CustomRadPdfViewerElement();
}
}
public class CustomRadPdfViewerElement : RadPdfViewerElement
{
public CustomRadPdfViewerElement()
{
}
public override void PrintPreview(RadPrintDocument document)
{
if (document != null)
{
document.AssociatedObject = this;
CustomPdfPrintPreviewDialog dialog = new CustomPdfPrintPreviewDialog(document);
dialog.ThemeName = ((RadControl)this.ElementTree.Control).ThemeName;
if (dialog.DialogResult != DialogResult.Abort)
{
dialog.ShowDialog();
}
dialog.Dispose();
}
}
}
public class CustomPdfPrintPreviewDialog : PdfPrintPreviewDialog
{
RadPrintDocument printDocument;
RadFixedDocument fixedDocument;
public CustomPdfPrintPreviewDialog(RadPrintDocument document) : base(document)
{
this.printDocument = document;
RadPdfViewerElement pdfViewerElement = printDocument.AssociatedObject as RadPdfViewerElement;
RadPdfViewer pdfViewer = printDocument.AssociatedObject as RadPdfViewer;
this.fixedDocument = pdfViewer == null ? pdfViewerElement == null ? null : pdfViewerElement.Document : pdfViewer.Document;
}
protected override void OnShowPrintSettingsDialog()
{
if (this.printDocument == null)
{
return;
}
PdfPrintSettingsDialog dialog = this.printDocument.AssociatedObject.GetSettingsDialog(this.printDocument) as PdfPrintSettingsDialog;
RadPageView pageView = dialog.Controls["radPageView1"] as RadPageView;
pageView.Pages.Last().Item.Visibility = ElementVisibility.Collapsed;
RadForm radDialog = dialog as RadForm;
if (radDialog != null)
{
radDialog.ThemeName = this.ThemeName;
}
if (dialog.ShowDialog() == DialogResult.OK)
{
this.printDocument.PrinterSettings.PrintRange = System.Drawing.Printing.PrintRange.AllPages;
this.UpdatePreview();
}
RadGroupBox radGroupBoxOrientation = this.Controls["radGroupBoxOrientation"] as RadGroupBox;
RadRadioButton radRadioButtonLandscape = radGroupBoxOrientation.Controls["radRadioButtonLandscape"] as RadRadioButton;
radRadioButtonLandscape.ToggleState = this.printDocument.Landscape && !this.printDocument.AutoPortraitLandscape ? ToggleState.On : ToggleState.Off;
RadRadioButton radRadioButtonAuto = radGroupBoxOrientation.Controls["radRadioButtonAuto"] as RadRadioButton;
radRadioButtonAuto.ToggleState = this.printDocument.AutoPortraitLandscape ? ToggleState.On : ToggleState.Off;
}
private void UpdatePreview()
{
if (this.fixedDocument == null || this.fixedDocument.Pages.Count == 0)
{
return;
}
this.UpdateScaleLabelText();
this.UpdatePaperSizeText();
this.UpdatePagePreview();
this.UpdateCurrentPageText();
}
}
I hope this information helps. Should you have further questions I would be glad to help.
