IButtonControl Interface


Allows a control to act like a button on a form.

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

type IButtonControl = interface end


Gets or sets the value returned to the parent form when the button is clicked.


Notifies a control that it is the default button so that its appearance and behavior is adjusted accordingly.


Generates a Click event for the control.

An example of where this interface might be implemented is default and cancel button processing. Default buttons are notified when an unprocessed ENTER key is entered for a form, just like a dialog box would be closed. Similarly, cancel buttons are notified whenever an unprocessed ESC key is entered on a form, much like a dialog box would be dismissed.

Notes to Implementers:

Implement this interface in classes that act as button controls. The members of this interface will provide basic button functionality, such as providing a DialogResult to the parent form or the ability to perform a Click event, or acting as the default button of a form.

The following example inherits from the ButtonBase class and implements the IButtonControl interface. Implementation is added to the DialogResult property and the NotifyDefault and PerformClick methods.
