List CheckBox Column (PRIM_LIST.CheckBox)

Column displaying a check box for each item in the list

Ancestors - List Column (PRIM_LIST.Column) Object (PRIM_OBJT)

Details

Prim_List.Checkbox is a column in a List that is visualized as a checkbox.
 
Each column type has a corresponding CurrentItem class that provides access to the individual entries in the column accessible via the CurrentItem property.
 
The checkbox for each item can be modified 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 checkbox column is created whenever a Check Box is dragged and dropped from the controls view.

Example

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