The following members accept/return IFileData objects:
You can create your own IFileData implementation when required. To see an example, refer to the FileData class sources at %PROGRAMFILES(x86)%\DevExpress 20.2\Components\%PROGRAMFILES(x86)%\DevExpress 20.2\.NET Core Desktop Libraries\Sources\DevExpress.Persistent\DevExpress.Persistent.BaseImpl\FileData.cs, or to the following articles: How to: Store file attachments in the file system instead of the database | How to: Store file attachments in Dropbox instead of the database(video).
When the File Attachments module is added to the application, business object properties of the IFileData type are visualized using the FileDataPropertyEditor in WinForms and ASP.NET applications.
If you want to access the full path to a file, implement the ISupportFullName interface in your class in addition to IFileData.
