More Data Binding

MultiBinding

Create a Person class with multiple properties, e.g. FirstName and LastName
Use MultiBinding with a StringFormat to display multiple properties within a TextBlock control

PriorityBinding

Create a data class that returns data after a blocking delay with Thread.Sleep
Bind the data class to the UI - what's the result of the blocking delay?
Use a PriorityBinding to avoid blocking and display intermediate results from a Info class

Validation

Create a data type that throws exceptions when a wrong value is set
Validate binding to the UI by setting the ValidatesOnExceptions property
Try using the IDataErrorInfo interface instead of throwing exceptions
Implement the INotifyDataErrorInfo and display errors after a delay
