Комментарии

Это свойство можно использовать для отображения захвата размера, чтобы предоставить пользователю указание на возможность изменения размера формы. Если для FormBorderStyle свойства Form задан стиль границы, который не допускает изменения размера, например Fixed3D или FixedDialog, следует задать свойству SizingGripfalse значение , чтобы пользователь не думал, что размер формы можно изменить.
