TypeValidationEventHandler Delegate


Represents the method that will handle the TypeValidationCompleted event of the MaskedTextBox control.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public delegate void TypeValidationEventHandler(
	object sender,
	TypeValidationEventArgs e


Type: System.Object

The source of the event.

Type: System.Windows.Forms.TypeValidationEventArgs

A TypeValidationEventArgs that contains the event data.

The TypeValidationCompleted event of the MaskedTextBox class is an optional event that is raised only if the ValidatingType property is explicitly set to a type other than null.

Typically, a handler for the TypeValidationCompleted event is implemented to perform mask-specific and type-specific validation processing. In contrast, general validation is typically performed in the standard Validating event defined in the Control base class.
