NuGet Package: DevExpress.Maui.Pdf
Declaration
public Command SelectPreviousAnnotation { get; }Property Value
| Type | Description |
|---|---|
| Command | A command that selects the previous annotation in the document. |
Remarks
The PDF viewer stores all document annotations in the Annotations collection. Once you or a user adds a new annotation, the PDF Viewer control re-sorts the Annotations collection to insert this annotation according to its position in the document. SelectPreviousAnnotation changes the focus to the previous annotation in the document and therefore in the Annotation collection. SelectPreviousAnnotation is disabled when you sequentially call SelectPreviousAnnotation to iterate through annotations and reach the first annotation in the document.
If no annotations are selected in the PDF viewer, the SelectPreviousAnnotation method selects the last annotation on the previous page. The PdfViewer.CurrentPageNumber property returns the index of the current page.
To select the next annotation, use the SelectNextAnnotation command.
