By default, the ItemsDelimiter property is "\r\n" ( Chr(13) & Chr(10), Carriage return-linefeed combination ). The ItemsDelimiter property specifies the delimiter sequence for drop down items. The ItemValueDelimiter property specifies the delimiter sequence for drop down value. The Caption property specifies the caption to be shown on the item. If the Caption property includes the ItemsDelimiter value, it indicates that the toolbar's item displays a drop down list, when user clicks the item. Each part of the Caption between two delimiters indicates an item in the drop down. For instance, "Item <b>A;Item <b>A#1;Item <b>B#2;Item <b>C#3" indicates that the toolbar's item displays the "Item A", and it's drop down list contains "Item A" with the value 1, "Item B" with the value 2 and "Item C" with the value 3.
