 In .NET MAUI PDF Viewer, you can implement custom save logic at the application level. If you would like to include a Save button in the built-in toolbar, this can be achieved by customizing the toolbar items. Refer to the {{'[Customize toolbar items user guide](https://help.syncfusion.com/maui/pdf-viewer/toolbar#customize-toolbar-items)'| markdownify }} for instructions on adding a custom Save button.

+<td>In the .NET MAUI PDF Viewer, there are no public APIs available to determine whether undo or redo actions are available, unlike in Xamarin.
+However, undo and redo actions are typically triggered when changes are made to the PDF document such as adding, editing, or removing annotations, or modifying form field values. These types of modifications can be detected using the annotation and form field events provided by the PDF Viewer. These events include:
+<br><br>
+{{'[AnnotationAdded](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.SfPdfViewer.html#Syncfusion_Maui_PdfViewer_SfPdfViewer_AnnotationAdded)'| markdownify }}- Occurs when an annotation is added to a page.
+{{'[AnnotationEdited](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.SfPdfViewer.html#Syncfusion_Maui_PdfViewer_SfPdfViewer_AnnotationEdited)'| markdownify }} - Occurs when annotation is modified.
+{{'[AnnotationRemoved](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.SfPdfViewer.html#Syncfusion_Maui_PdfViewer_SfPdfViewer_AnnotationRemoved)'| markdownify }} - Occurs when an annotation is removed from the page.
+{{'[FormFieldValueChanged](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.SfPdfViewer.html#Syncfusion_Maui_PdfViewer_SfPdfViewer_FormFieldValueChanged)'| markdownify }} - Occurs when when the values of the form fields are changed in the PDF.

+By handling these events, you can determine whether any modifications have been made to the PDF document.
