This example demonstrates how to upload an image for editing in the Image Editor by using an Ajax Request in the OnClientFilesUploaded event of RadAsyncUpload. RadImageEditor offers a variety of server-side methods and events that enable you to manipulate an image on the server, not just on the client. You can use the OnImageLoading event to change the image that will be loaded according to some custom logic. This event is fired just before the image is loaded from the file system. The event can be cancelled and the edited image loaded from a custom location. Note that the OnImageLoading event is fired only when the ImageEditor needs to load the initial image.
