In this demo, the ASPxUploadControl's client and server functionality are used to upload an image file to the server, create the image's thumbnail and display the thumbnail image within a specific placeholder on the web page.

The main properties used in the demo are listed below:

The ShowProgressPanel property enables a progress panel to be displayed during the upload process.
The NullText property is used to display a prompt text in a text box.
The MaxFileSize property is used to specify the maximum file size allowed for upload.
The AllowedFileExtensions property restricts the allowed file extensions of the upload.
