Examples
The following example shows a call to the getItem method to return a FormListItem object for each item in the form list control. The FormListItem.toString method returns a text string for each item.
The while select statement retrieves account numbers from the CustTable table and then stores the data in a container. The items in the variable are added to the form list control by calling the FormListControl.addItem method.
