Silverlight 4 Databinding and VS2010

1 min read

If you've got a data driven application, databinding is the infrastructure of choice that makes the link between data and your UX.

Silverlight 4 has a few improvements that bring it closer to WPF.

  • TargetNullValue - lets you specify what to display in the target when the source value is null

e.g. {Binding Path=Name, TargetNullValue=NoName}

  • StringFormat - specify how a string should be formatted

e.g. {Binding Path=Salary, StringFormat=C}

  • FallbackValue - I love this one, comes in pretty handy when dealing with polymorphic classes where you know in advance what properties specialized classes have and want to display them... or display a fallback value if they don't exist.

e.g. {Binding Path=LastLoggedOn, FallbackValue=Never}
