BindingManagerBase.PositionChanged 이벤트

Position 속성 값이 변경된 후 발생합니다.

네임스페이스: System.Windows.Forms
어셈블리: System.Windows.Forms(system.windows.forms.dll)

구문

‘선언
Public Event PositionChanged As EventHandler
‘사용 방법
Dim instance As BindingManagerBase
Dim handler As EventHandler

AddHandler instance.PositionChanged, handler

public event EventHandler PositionChanged

public:
event EventHandler^ PositionChanged {
    void add (EventHandler^ value);
    void remove (EventHandler^ value);
}

/** @event */
public void add_PositionChanged (EventHandler value)

/** @event */
public void remove_PositionChanged (EventHandler value)

JScript에서는 이벤트를 사용할 수 있지만 새로 선언할 수는 없습니다.

예제

다음 코드 예제에서는 Binding을 만든 다음 TextBox 컨트롤에 대한 Binding 개체의 컬렉션에 추가합니다. 그런 다음 예제에서는 데이터 소스에 대한 BindingManagerBase를 가져오고 대리자를 PositionChanged 이벤트에 추가합니다.
