Named Actions
As of Q1 2025 RadPdfProcessing provides support for Named actions that PDF viewer applications are expected to support. The NamedAction class offers the public Type property which specifies the type of the action representing the menu item to be executed.
The available Standard NamedActionType options are listed in the table below.
The PDF viewer applications are expected to support the standard name actions. Further names may be added as well but it is not guaranteed that all PDF viewers would support the NonStandard actions:
| Standard Names Actions | Description |
|---|---|
| NextPage | Go to the next page of the document. |
| PrevPage | Go to the previous page of the document. |
| FirstPage | Go to the first page of the document. |
| LastPage | Go to the last page of the document. |
Viewer applications may support additional, nonstandard named actions, but any document using them is not portable. If a viewer (e.g. Adobe Acrobat, RadPdfViewer or a web browser) encounters a named action that is inappropriate for a viewing platform, or if the viewer does not recognize the name, it should take no action.
RadPdfProcessing offers support for the following NonStandard Named actions as well:

Adding a Named Action to a PushButtonField
The following example demonstrates how to create a PDF document with a PushButtonField which triggers a printing action when the document is displayed in a viewer and the button is pressed by the end-user:
PushButtonField pushButtonField = new PushButtonField("SamplePushButton");
PushButtonWidget widget = pushButtonField.Widgets.AddWidget();
widget.Rect = new Rect(10, 10, 250, 50);
widget.HighlightingMode = HighlightingMode.InvertBorderOfAnnotationRectangle;
NamedAction printAction = new NamedAction(NamedActionType.Print);
widget.Actions.MouseUp.Add(printAction);
widget.AppearanceCharacteristics.Background = new RgbColor(123, 165, 134);
widget.AppearanceCharacteristics.NormalCaption = "Print";
widget.TextProperties.FontSize = 20;
widget.TextProperties.Fill = new RgbColor(0, 0, 0);
widget.RecalculateContent();
RadFixedDocument fixedDocument = new RadFixedDocument();
fixedDocument.Pages.AddPage();
fixedDocument.AcroForm.FormFields.Add(pushButtonField);
fixedDocument.Pages[0].Annotations.Add(widget);
