The DatePicker::DateValidationError event occurs when DatePicker::Text is set to a value that cannot be interpreted as a date or when the date cannot be selected. You can subscribe to this event and specify whether an exception is raised by setting the ThrowException property. If DatePickerDateValidationErrorEventArgs::ThrowException is true, one of the following exceptions is raised:

Exception type

Condition

FormatException

The text entered cannot be parsed to a valid date, and the exception is not suppressed.

ArgumentOutOfRangeException

The text entered parses to a date that is not selectable.

If DatePickerDateValidationErrorEventArgs::ThrowException is false, the application continues execution as usual.

The following example creates a DatePicker that displays the dates in August 2009 and specifies that each Saturday and Sunday is not selectable. The DatePicker handles the DateValidationError event. If the user enters a date that is not selectable, the example displays a message. If the user enters text that is not a valid date, an exception is thrown.
