XAML Binding error, cannot find sourceHello,
I do get a binding error when trying to bind a string from codebehind as content of a ComboBoxItem in CompositeCollection.
<ComboBox.ItemsSource>
<CompositeCollection>
<ComboBoxItem Visibility="Collapsed" Content="{Binding Test, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:MultiSelectionDropdown}}}"/>
<CollectionContainer Collection="{Binding Source={StaticResource ResourceKey=Pipeline}}"/>
</CompositeCollection>
</ComboBox.ItemsSource>
