Type Description

A FileManagerFileUploadEventHandler delegate method to be called when a file is about to be uploaded within the FileManager upload panel.


Implement a FileManagerFileUploadEventHandler delegate method and assign it to the FileUploading property. For more implementation details, refer to the FileManagerFileUploadEventHandler delegate description.

Before each time a file is uploaded on the server side, the FileUploading event occurs, allowing you to cancel the file upload. The event parameter’s FileManagerFileUploadEventArgs.File property identifies the file that is being processed. To cancel the upload operation, set the FileManagerActionEventArgsBase.Cancel property to true. In order to show a message explaining the reason for the upload cancellation, specify the FileManagerActionEventArgsBase.ErrorText property.
