Public Enum CurrentPageNumberChangedCause
enum class CurrentPageNumberChangedCause sealed
|0||Visibility||The current page number was updated because the new page's visibility became greater than the old page's visibility. This can occur due to scrolling, page navigation, zooming, etc.|
|1||Activity||The current page number was updated because the new page was interacted with, either by mouse/pointer interaction or through a DocumentViewerCommand that set the page's ImageViewerItem as the ImageViewer.ActiveItem.|
The CurrentPageNumberChangedCause can be viewed when DocumentViewer.CurrentPageNumber changes through the CurrentPageNumberChangeData.Cause property of DocumentViewerOperationEventArgs.Data1 for a DocumentViewerOperation.CurrentPageNumberChanged operation.
