Provides access to the edit field of the current list item
Ancestors - List CurrentItem (PRIM_MD.ListCurrentItem)Object (PRIM_OBJT)
Details
Prim_MD.ListEdit is a control List that is visualized as a Edit. Each control type has a corresponding control class that provides access to the control instance. The Edit 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 Edit control is created whenever a Edit 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 Edit is changed the current item for the control is accessed and the caption shows which button was clicked.
