Description
In previous examples, we already use .Items several times (see Getting Started with DelphiVCL III: Overview of Commonly used VCL Components). We use it in ListBox, ComboBox, and RadioGroup. Items contain the strings that appear in the ListBox, ComboBox, and RadioGroup.
Use Items to add, insert, delete, and move items. By default, the items in a list box are of type Strings. Use this item type to access its methods or properties to manipulate the items in the list.
