Provides access to the reusable part for the current list item
Ancestors - List Current Item (PRIM_LIST.CurrentItem)Object (PRIM_OBJT)
Details
Prim_List.Part is a column in a List used to present an instance of a reusable part rather than the typical field based cell. Each column type has a corresponding Column class that provides access to the individual entries in the column. The reusable part for each item can be accessed independently using the current item for the column in the same way that other visual LANSA lists allow the current item for the list to be used. A part column is created whenever a reusable part is dropped on the list. The Design property defines the class of part being used. The *ListFields parameter used in the resuable part will define the data fields for the column.
Example
In this example, a simple part displays an address as a single cell rather than using 4 separate columns.
