* Added HideDropdownListOnClick property. * Invoking OpenSelectedItem on click. * Added one more constructor and more unit tests. * Added the ComboListView derived class. * Added more features to ComboBox. * Removes code not featured yet. * Added HideDropdownListOnClick property to scenario. * Ensures SetSource having the same behavior as the ListWrapper constructor.
