Declaration
Remarks
By default, an Object type business class property is displayed via a Lookup Property Editor. The drop-down frame of this Property Editor contains a List View that displays all existing objects of the specified type. In addition, this frame can contain a Search function, so that end-users can easily find a particular object in that List View. Apply the LookupEditorMode attribute to a property, to specify whether the Lookup Editor should contain the Search function.
