Question

I have a MenuItem that I’d like to populate with sub-items. However, I’d like for it to keep the items it already has:

<MenuItem Header="_Profiles">
    <MenuItem Header="_New Profile..." />
    <Separator />
    <!-- Databind here! -->
</MenuItem>

However, when I try to use normal declarative databinding it eliminates the two subitems I’ve declared.

I’m sure there has to be a way to do this but I can’t figure it out and I’m not sure any of my Google searches have been that good; can anyone help?

Thanks!

One approach is to utilize a CompositeCollection:

<MenuItem Header="_File">
    <MenuItem.ItemsSource>
        <CompositeCollection>
            <MenuItem Header="_New" />
            <Separator />
            <CollectionContainer Collection="{Binding MenuItems}" />
            <Separator />
            <MenuItem Header="E_xit" />
        </CompositeCollection>
    </MenuItem.ItemsSource>
</MenuItem>
