DataGridBoolColumn.FalseValueChanged イベント

.NET Framework クラス ライブラリ リファレンス

DataGridBoolColumn.FalseValueChanged イベント

FalseValue プロパティが変更されると発生します。

名前空間: System.Windows.Forms
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)
構文

Visual Basic (宣言)

Public Event FalseValueChanged As
 EventHandler

Visual Basic (使用法)

Dim instance As DataGridBoolColumn
Dim handler As EventHandler

AddHandler instance.FalseValueChanged, handler

C#

public event EventHandler FalseValueChanged

C++

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

J#

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

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

JScript

JScript では、イベントは使用できますが、新規に宣言することはできません。
