I want to make a ComboBox whose elements are a subset of the members of an enum type. If I once knew the syntax for this, I can’t remember it now!

I’m basically looking for the markup equivalent of throwing this into the constructor:

        cboState.Items.Add(InvoiceState.Ready);
        cboState.Items.Add(InvoiceState.Waiting);
        cboState.Items.Add(InvoiceState.Finished);

Simply binding to Enum.GetValues doesn’t work because there are values I don’t want to include. If these were in attribute values, I could use {x:Static core:InvoiceState.Ready}, etc. But they’re not attribute values.

            <ComboBox Name="cboState">
                <!-- what goes here? -->
                <core:InvoiceState>Ready</core:InvoiceState> <!-- does not work -->
            </ComboBox>
