MessageBoxButton Enumeration
Assembly: PresentationFramework (in presentationframework.dll)
XML Namespace: http://schemas.microsoft.com/winfx/2006/xaml/presentation
By default, the Show method of the MessageBox type displays a message box that has an OK button. You can use overloads of the Show method that accept a MessageBoxButton argument in order to specify different combinations of buttons, which include OK, OK/Cancel, Yes/No, and Yes/No/Cancel.
If you specify YesNo, you disable the Close button in the message box title bar. However, the Close button is enabled for all other options. When a user clicks the Close button or presses the ESC key, a message box returns a message box result value of Cancel. However, if a message box displays only an OK button, clicking the Close button or pressing the ESC key causes a message box to return a message box result value of OK.
The value of the button that a user clicks is returned by Show and is one of the values of the MessageBoxResult enumeration.
