    Chaining Combos
</h1>
<p>
    ComboBox controls automatically create CollectionView
    objects based on their <b>itemsSource</b>, and expose
    this view through the <b>collectionView</b> property.
</p>
<p>
    You can use this feature to apply filters to the combo
    items. For example, when you select a country from the
    first combo below, the second will be filtered to show
    only cities in that country:

@Html.C1().ComboBox().Id("cmbCountry").DisplayMemberPath("name")
@Html.C1().ComboBox().Id("cmbCity").DisplayMemberPath("name")
