I have a collection ObservableCollection<Foo>, and I want to bind this to a property in a custom controller of type ObservableCollection<object>. However, the bound value never reaches the PropertyCallback, and is hence never set.
Is there a clever way to achieve this binding? I could create an IValueConverter that converts from ObservableCollection<Foo> to ObservableCollection<object>, but that gives new problems..
As far as I know, there is no automatic conversion. Writing a ValueConverter is an option.
If you have often the need for this specific conversion, maybe a TypeConverter can do what you need. After creating, declare it with the TypeConverterAttribute, then in bindings automatic conversion will be done.
