    as soon as the user selects the item.Selection is indicated by a tick mark on the left of selected row.<br>

    <b>NoSelection</b>: User can select one item from the list at a time and the SelectionDialog will be dismissed 
    as soon as the user selects the item.No indicator is show on selection.<br>
