List Label CurrentItem (PRIM_MD.ListLabelCurrentItem)
Provides access to the label of the current list item
Ancestors - List CurrentItem (PRIM_MD.ListCurrentItem) Object (PRIM_OBJT)
Prim_MD.ListLabel is a control List that is visualized as a Label. Each control type has a corresponding control class that provides access to the control instance. The Label for each item can be modified independently using the current item for the control in the same way that other visual LANSA lists allow the current item for the list to be used. A Label control is created whenever a Label is dragged and dropped from the controls view.
This example shows a single control list updating each label after it's added to the list. When a Label is changed the current item for the column is accessed and the label caption shows which Label was clicked.
