How do you bind to nested properties and handle null paths safely?

Intermediate

Answer

Use dot paths like {Binding Order.Customer.Name}. If intermediate values can be null, bindings resolve to empty rather than throwing, but you can supply FallbackValue and TargetNullValue for clarity. Compiled bindings (x:DataType) validate the path at build time.
<Label Text="{Binding Order.Customer.Name,
    TargetNullValue='Unknown', FallbackValue='—'}" />
Real-world example A summary label shows 'Unknown' when a customer isn't loaded yet, avoiding a blank UI.
