WPF: Multiple Types in ComboBox ItemsSource

[Wonko the Sane]

Hello,

I have two data-bound comboboxes (using List<Class1> and List<Class2>),
which are both displayed but have mutually exclusive options. A value should
be taken from one or the other as an option for the user.

As such, I'd like to put "Uses ClassX" as the first item in each of the lists:

Combo1 Combo2
--------- -----------
Use Class2 Use Class1
Class1 Item1 Class2 Item1
Class1 Item2 Class2 Item2
etc. etc.

These combos are being bound in code. Is there a way to add the "Use
ClassX" as an item in a bound list?

Thanks,
WtS

Hi WtS,

I think you can use CompositeCollection to do this. It can combine multiple
sources for databinding. Here's some example:
