An enumeration detailing the cause of DocumentViewer.CurrentPageNumber changes.
public enum CurrentPageNumberChangedCause public:enum class CurrentPageNumberChangedCause sealed
| Value | Member | Description |
|---|---|---|
| 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.
