ContainerControl.AutoValidate 속성

정의

포커스가 변경될 때 이 컨테이너의 컨트롤에 대한 유효성 검사가 자동으로 수행되는지를 나타내는 값을 가져오거나 설정합니다.Gets or sets a value that indicates whether controls in this container will be automatically validated when the focus changes.

public:
 virtual property System::Windows::Forms::AutoValidate AutoValidate { System::Windows::Forms::AutoValidate get(); void set(System::Windows::Forms::AutoValidate value); };
[System.ComponentModel.Browsable(false)]
public virtual System.Windows.Forms.AutoValidate AutoValidate { get; set; }
member this.AutoValidate : System.Windows.Forms.AutoValidate with get, set
Public Overridable Property AutoValidate As AutoValidate

속성 값

포커스가 변경될 때 암시적으로 포함된 컨트롤의 유효성을 검사할지 여부를 나타내는 AutoValidate 열거형 값입니다.An AutoValidate enumerated value that indicates whether contained controls are implicitly validated on focus change. 기본값은 Inherit입니다.The default is Inherit.

특성

예외

유효하지 않은 AutoValidate 값을 사용하여 이 속성을 설정한 경우A AutoValidate value that is not valid was used to set this property.

예제

다음 코드 예제는 양식 및 포함된 된 컨트롤의 모든 암시적 유효성 검사가 해제 하 고 마우스 단추를 클릭할 때 대신 유효성 검사의 모든 폼의 자식을 수동으로 수행 합니다.The following code example turns off implicit validation for a form and all of its contained controls, and instead manually performs validation of all of the form's children when a mouse button is clicked.

설명

에 대 한 기본값 AutoValidate 각 컨트롤에 대해 다릅니다.The default value for AutoValidate will differ for each control. 암시적 유효성 검사에 대 한 자세한 내용은 참조 하세요. Windows Forms에서 사용자 입력 유효성 검사합니다.For more details on implicit validation, see User Input Validation in Windows Forms.

이 속성을 새 값을 발생 시킵니다는 AutoValidateChanged 이벤트입니다.Setting this property to a new value will raise the AutoValidateChanged event.
