Recipe 4.9. Indicating the Accept and Cancel Buttons on a Form


Problem

On a form, you want to have the Enter key trigger a specific button (such as an "OK" button) and have the Escape key trigger another button (such as a "Cancel" button).

Solution

Use the form's AcceptButton and CancelButton properties to assign the appropriate buttons. In the Visual Studio Form Designer, setting these form properties to the names of buttons on the form will enable the keyboard shortcuts for those buttons.

Discussion

Setting a button to be a form's CancelButton object has the side effect of changing that button's DialogResult property to Cancel.

Even if you set an accept button, the Enter key doesn't always trigger it. For instance, if another button on the form has the focus, that button, and not the form's accept button, is triggered when the user presses the Enter key.
