Access registered cloud storage data providers (RegisteredProviders).
Set a registered data provider as active (ProviderClassName and ProviderClass).
Access the active data provider and associate it with the corresponding authorization agent (Provider).
Obtain information on any occurring file operation errors (OnError).
Manage the connection to a file storage account (Connected).

Download files and receive downloaded content (DownloadFile and OnItemDownloaded).
Upload new and update existing files (UploadFile).

Track the start and successful finish of content structure synchronization between the cloud storage component and the connected cloud storage service’s server (OnTreeDataLoading and OnTreeDataLoaded).
Track added and revoked access permissions (OnItemPermissionCreated and OnItemPermissionDeleted).
Refresh displayed lists of access permissions for individual files and folders (OnItemPermissionsLoaded).
Track the start and successful finish of data synchronization between your application and the connected server (OnFileContentUploading, OnFileContentUploaded, OnItemDownloading, OnItemDownloaded, OnItemUploading, and OnItemUploaded).
