MessageBoxResult Enumeration

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Specifies which message box button that a user clicks. MessageBoxResult is returned by the Show method.

Namespace:  System.Windows
Assembly:  PresentationFramework (in PresentationFramework.dll)
public enum MessageBoxResult
<object property="enumerationMemberName" .../>
Member name Description
None The message box returns no result.
OK The result value of the message box is OK.
Cancel The result value of the message box is Cancel.
Yes The result value of the message box is Yes.
No The 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.
