WebFileUploader is designed with rock-solid API and extensible client-side events to give you total control over uploading process. Works in conjunction with real-time progress bar feature, WebFileUploader sent event notification to client-side in real-time - such as OnBeforeUpload, OnAfterUpload OnErrorUpload, and even OnUploading event.

The following lists the available client side events in more details:

OnInitialize.
Fired once when the control is initialized.
OnBeforeUpload.
Fired when a file is about to be uploaded.
OnAfterUpload.
Fired when a file has been successfully uploaded.
OnUploading.
Fired when uploader control receives progress information on a file being uploaded.
OnCancelUpload.
Fired when a file upload is cancelled.
OnErrorUpload.
Fired when a file upload is failed due to error.

The following example shows how to handle the client-side events, and shows the information passed to the parameter of each event.
