Return Value
Type: int
An Integer data type value that indicates the number of items that are selected in a form list control.
Examples
The following example shows a call to the getSelectedCount method to return the number of items that are selected in the form list control.
The FormListControl.singleSelection method indicates whether multiple items can be selected.
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.
