Gets a value indicating whether the formatted input string was successfully converted to the validating type.
true if the formatted input string can be converted into the type specified by the ValidatingType property; otherwise, false.
The IsValidInput property indicates the success of the Parse method found in the Type represented by the ValidatingType property. This type must contain Parse method(s) having one or both of the following signatures:
public static Object Parse(string)
public static Object Parse(string, IFormatProvider)
Parse is called before the MaskedTextBox control raises the TypeValidationCompleted event. This method is invoked with the contents, minus the prompt characters, of the Text property of the MaskedTextBox class. If successful, it returns the converted object; otherwise, it returns a null reference (Nothing in Visual Basic).
