On AddMovieClick please comment every thing else and test this one it will show you current items selected .

if (CategorylistBox.SelectedItems != null)
{
    foreach (var item in CategorylistBox.SelectedItem.ToString())
    {
        Debug.WriteLine("current item "+item);
        // CinemaDataSetTableAdapters.QueriesTableAdapter kTyp = new CinemaDataSetTableAdapters.QueriesTableAdapter();
        // kTyp.AddCategoryType((selectedItem), TitleTextBox.Text);
    }
}
