This event is generated when the mouse is moved over a thumbnail image in the Thumbnail Control.
Event Data
The event handler retrieves arguments of type ThumbnailEventArgs
Explanation
The MouseMoveOnThumbnail event is generated when the mouse is moved over a thumbnail image in the Thumbnail Control. If the thumbnail image is not completely displayed on the thumbnail control then this event is not generated or if the AllowDrag property is true and the thumbnail image is being dragged within the Thumbnail Control.
Information about files loaded during this event can be referred to within the ThumbnailLoadEventArgs arguments.
Regarding properties for the ThumbnailEventArgs class
When the thumbnail image isn't displayed into the thumbnail frame that was moved over with the mouse, the DirectoryName and FileName parameters will return an empty string (String.Empty) and the ImageNumber and the PageNumber will return -1.
When multi-page image files are loaded, the page number is appended to the FileName parameter (If the page number is 0 then it is omitted).
Example: When page 2 of the file ABC.TIF is loaded into the thumbnail control, the FileName parameter will return the string "ABC.TIF 2"
