CustomGetValueEventArgs	Arguments passed to the ObjectFormatter.CustomGetValue event.
DataSourceCriteriaAttribute	Applied to business classes‘ reference and collection properties. Specifies the criteria expression used to filter the List View displayed in a Lookup Property Editor or invoked by the LinkUnlinkController.LinkAction Action in a popup window.
DataSourceCriteriaPropertyAttribute	Applied to business classes‘ reference and collection properties. Specifies the name of a CriteriaOperator type property which returns data source’s filter criteria applied to the List View displayed in a Lookup Property Editor or invoked by the LinkUnlinkController.LinkAction Action in a popup window.
DataSourcePropertyAttribute	Applied to business classes‘ reference and collection properties. Specifies the name of a collection property used as the data source for a List View displayed in a Lookup Property Editor or invoked by the LinkUnlinkController.LinkAction Action in a popup window.
DefaultClassOptionsAttribute	Sets default options for a class.
EditorAliasAttribute	Specifies the Property Editor alias.
ExpandObjectMembersAttribute	Specifies whether the target reference property is displayed via several Property Editors representing the referenced object’s properties or via a single Lookup or Object Property Editor.
FileAttachmentAttribute	Applied to business classes that expose a property of the IFileData type. Activates Controllers that manage file attachments for the target business class. Specifies a property that stores a file attachment.
FileTypeFilterAttribute	Applied to file data business classes, interfaces and their properties. Specifies a file type filter which appears in the Open dialog’s “Files of type” box.
FriendlyKeyPropertyAttribute	Specifies the property which is considered an analog of the GUID property, to allow use of more suitable values.
ImageEditorAttribute	Applied to business class properties of the byte array type. Specifies that the target property persists an image. Attribute parameters specify settings to be used by Image Property Editors when displaying images persisted by the target property.
ImageNameAttribute	Specifies the name of the image that is displayed for the target class’ objects or target enumeration value.
ImagesForBoolValuesAttribute	Applied to Boolean business class properties. Specifies the names of the images used to display the target property’s values.
ImmediatePostDataAttribute	An attribute you can apply to business class properties. This attribute indicates that the Property Editor’s control value should be passed to the property of a bound object as soon as possible when a user changes the editor’s value.
IndexAttribute	Specifies the target business class property’s order index, that will be considered when generating layout items in a Detail View, and columns in a List View.
LookupEditorModeAttribute	Specifies the mode of the target business class property’s Lookup Property Editor.
