Something like:
<TextBlock Text="{Binding Text,Converter={StaticResource
ccc},ConverterParameter=PersonName}"/>
when Person name is Property of the class for example.
Update:
I’ve seen a solution that tells to inherit from DependencyObject and to implement IValueConverter.
I want to know if there is something simpler.
The answer is straight-forward, but not what you want to hear.
You can only target a binding at DependencyProperty on a DependencyObject. Binding does not inherit from DO, so you can’t binding the converter parameter.
If you want other state passed into a converter, you may have to subclass the desired obect and add new properties
