Image Uploader

Last update: Download PDF Edit

An image uploader is used to upload images to the server. It also generates a thumbnail of the uploaded image. The uploaded image or its thumbnail can be shown by use of the image viewer.

The image uploader is placed in a nested data view here. The Profile entity is a specialization of System.Image.

An image uploader must be placed in a table cell within a data view. This data view must be connected to entity System.Image or a specialization thereof.
