Adding a listbox


In the case of the collapsed ComboBox control, only one item is presented. However, if you want to show more items as well as allow to select multiple elements in the same time, you can use ListBox. The usage of this control is explained in this recipe.

                    <ListBox 
                        SelectedIndex="1"

                        VerticalAlignment="Center" 
                        HorizontalAlignment="Center"> 
                        <ListBoxItem Content="Polish" Tag="PL" />
