This example illustrates how to show a conformation message to overwrite an existing file in the ASPxFileManager.
The conformation message is shown in the client-side ASPxClientFileManager.FileUploading event and gives an option to the user to either overwrite the existing file or cancel the operation. User's selection is then transferred to the server-side via an ASPxHiddenField. If the user chooses to overwrite the file, the existing file will be deleted in the ASPxFileManager.FileUploading event.
