Комментарии

Это свойство позволяет назначить действие по умолчанию, выполняемое при нажатии пользователем клавиши Ввод в приложении.This property enables you to designate a default action to occur when the user presses the ENTER key in your application. Кнопка, назначенная этому свойству, должна быть IButtonControl, находящейся в текущей форме или расположенной в контейнере в текущей форме.The button assigned to this property must be an IButtonControl that is on the current form or located within a container on the current form.

Это свойство позволяет пользователю быстро перемещаться по простой форме, позволяя им просто нажать клавишу ВВОД после их завершения вместо того, чтобы вручную нажать кнопку Accept с помощью мыши.You can use this property to allow the user to quickly navigate a simple form by allowing them to simply press the ENTER key when they are finished instead of manually clicking the accept button with their mouse.

Кнопка принять может быть не активирована, если текущий выбранный элемент управления в форме перехватывает клавишу ВВОД и обрабатывает его.The accept button might not be activated if the currently selected control on the form intercepts the ENTER key and processes it. Например, многострочный элемент управления "текстовое поле" позволяет нажать клавишу ВВОД, если он выбран для вставки символа новой строки в элемент управления.For example, a multiline text box control allows the ENTER key to be pressed when it is selected to insert a new line character in the control.
