IButtonControl Interface
Allows a control to act like a button on a form.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
| Name | Description | |
|---|---|---|
![]() | DialogResult | Gets or sets the value returned to the parent form when the button is clicked. |
| Name | Description | |
|---|---|---|
![]() | NotifyDefault(Boolean) | Notifies a control that it is the default button so that its appearance and behavior is adjusted accordingly. |
![]() | PerformClick() | 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.
