FormListControl.getSelectedCount Method

Definition

Retrieves the number of items that are selected in a form list control.

public:
 virtual int getSelectedCount();
public virtual int getSelectedCount ();
abstract member getSelectedCount : unit -> int
override this.getSelectedCount : unit -> int
Public Overridable Function getSelectedCount () As Integer

Returns

An Integer data type value that indicates the number of items that are selected in a form list control.

Remarks

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.
