Bind a collection inside a collection in WPF combobox

Question

ObservableCollection<A> work = new ObservableCollection<A>();     
Class A
{
     int a;
     int b;
    observablecollection<string> c;
}

I need to bind" work" as the Itemsource of combobox and selectedItem as A. But I need to display the strings(c) of class A in the combobox. How will I display the strings C in the combobox. Any idea.?

does each item of the `ComboBox` have to show a list of strings? — Viv, Jul 01 '13 at 11:21

well if you need each ComboBoxItem to display a collection of strings, use an ItemsControl in the ItemTemplate of ComboBox.

<ComboBox ItemsSource="{Binding work}">
    <ComboBox.ItemTemplate>
        <DataTemplate>
            <StackPanel>
              <TextBlock Text={Binding a} />
              <TextBlock Text={Binding b} />
              <ItemsControl ItemsSource="{Binding c}" /> 
            </StackPanel>
        </DataTemplate>
    </ComboBox.ItemTemplate>
</ComboBox>
