Explanation
The ClearOnLoad property sets whether or not previously loaded images are cleared when an image is loaded into the Thumbnail Control. True is the default value. When False, the image loaded is added to the previously loaded images. A good example of when to use this property is when using an ADF to continuously scan images or when retrieving multiple images, one by one, from a datasource.
When this property is False, the ThumbnailFile property will be disabled and the thumbnail file will not be created.
