Ancestors - List CurrentItem (PRIM_MD.ListCurrentItem)Object (PRIM_OBJT)

Details

Prim_MD.ListSpinEdit is a control List that is visualized as a SpinEdit.
 
Each control type has a corresponding control class that provides access to the control instance.
 
The SpinEdit 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 SpinEdit control is created whenever a SpinEdit is dragged and dropped from the controls view.

Example

This example shows a single control list updating each button after it's added to the list.
 
When a SpinEdit is changed the current item for the column is accessed and the column caption shows which button was clicked.
