public property TCustomComboBox.ItemIndex : Integer |
ItemIndex is an Integer property which contains the ordinal position in Items for the current list box selection in the control. The first value in Items is at index position 0 (zero). The final value in Items is at the index position ItemCount-1. When no value is selected in the list box, ItemIndex is set to -1. The default value for the property is -1.
When the value for the property is read, the widgetset class is queried when a handle has been assigned for the control.
Assigning a new value to the property causes the value in Text to be updated to reflect the new selection in the control. When ItemIndex is -1, Text is set to an empty string ('').
