Returns or sets whether a row is selected (for listbox-type selections).
Public Property IsSelected(ByVal Index As Integer) As Boolean
This property allows you to select individual rows, not necessarily adjacent.
To implement this type of row selection, you will typically set the SelectionMode property to flexSelectionListBox, which allows the user to select individual rows using the mouse or the keyboard, and to toggle the selection for a row by CTRL-clicking on it.
You may enumerate the selected rows using the SelectedRows and SelectedRow properties.
