List box-specific properties at runtime

You can use properties that are specific to the List Box control at run time.

• The Count property returns the number of items in a List Box control.

• The NewIndex property returns the index of the last item added to the List Box list.

• The SelectedValue property reads the value of the selected item, or selects the item with that value if it exists.

• The TopIndex property returns the index of the top most item in the list.

These properties are available when you browse for a List Box control in your HMI's attribute/tag browser.
