Obsolete. Fires on the client side before a file upload starts, and allows you to cancel the action.
The FileUploading event handler receives an argument of the ASPxClientFileManagerFileUploadingEventArgs type. The following properties provide information specific to this event.
|cancel||Gets or sets a value indicating whether the action which raised the event should be canceled.|
|fileName||Gets the name of a file selected for upload.|
|folder||Gets the path to the folder where a file is being uploaded.|
Each time a file is going to be uploaded on the client side, the FileUploading event occurs, allowing you to cancel the action. You can use the event parameter's properties to identify a file name (ASPxClientFileManagerFileUploadingEventArgs.fileName) or a folder, where the file will be uploaded (ASPxClientFileManagerFileUploadingEventArgs.folder).
To cancel the upload operation, set the ASPxClientFileManagerFileUploadingEventArgs.cancel property to true.
After a file has been uploaded, the ASPxClientFileManager.FileUploaded event is raised.
