Allows a control to act like a button on a form.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Thetype exposes the following members.
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.
