Public Enumeration MessageBoxResult
<object property="enumerationMemberName" .../>

Member nameDescription
NoneThe message box returns no result.
OKThe result value of the message box is OK.
CancelThe result value of the message box is Cancel.
YesThe result value of the message box is Yes.
NoThe result value of the message box is No.

Show returns a MessageBoxResult value that specifies which button on a message box a user clicked. MessageBoxButton specifies which buttons are displayed on a message box.

The result value that is returned from a message box depends on what buttons the message box has and how a user closes a message box:

  • On a message box that has an OK button, OK is returned if a user clicks the OK button, clicks the Close button in the title bar, or presses the ESC key.

  • On a message box that has an OK button and a Cancel button, OK is returned if a user clicks the OK button. If a user clicks the Cancel button or the Close button in the title bar, Cancel is returned.

  • On a message box that has a Yes button and a No button, the Close button in the title bar is disabled. Consequently, Yes is returned if a user clicks the Yes button, and No is returned if a user clicks the No button.

  • On a message box that has a Yes button, a No button, and a Cancel button, Yes is returned if the Yes button is clicked and No is returned if the No button is clicked. If a user clicks the Cancel button or the Close button in the title bar, Cancel is returned.
