Syntactic Validation

Syntactic validation ensures that data entered by a user can be converted to the type required by the application. For example, when a user enters a date string into a TextBox, the input fails syntactic validation if it cannot be converted to a date.

In most cases, the XAML data-binding system attends to syntactic validation, coercing values to and from source property types.

Note

The XAML data-binding system performs syntactic validation before assigning a value to a property.
