If successful, an Object of the type specified by the ValidatingType property; otherwise, null reference (Nothing in Visual Basic) to indicate conversion failure.
The ValidateText method attempts to convert the formatted string contained in the Text property to an instance of the type that is specified by the ValidatingType property. Prompt characters are ignored in the formatted string, but literals are handled in accordance with the current value of the TextMaskFormat property.
ValidateText raises the TypeValidationCompleted event after the conversion is attempted, regardless of its success.
