MonthCalendar.DateChanged イベント

MonthCalendar で選択された日付が変更された場合に発生します。

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

Visual Basic (宣言)
Public Event DateChanged As
 DateRangeEventHandler
Visual Basic (使用法)
Dim instance As MonthCalendar
Dim handler As DateRangeEventHandler

AddHandler instance.DateChanged, handler
C#
public event DateRangeEventHandler DateChanged
C++
public:
event DateRangeEventHandler^ DateChanged {
    void add (DateRangeEventHandler^ value);
    void remove (DateRangeEventHandler^ value);
}
J#
/** @event */
public void add_DateChanged (DateRangeEventHandler
 value)

/** @event */
public void remove_DateChanged (DateRangeEventHandler
 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。
解説解説

DateChanged イベントは、マウス、キーボード、コードのどの方法で日付を選択しても発生します。DateSelected イベントは、これと似ていますが、マウスを使用した日付選択の終了時にだけ発生します。

イベント処理の詳細については、「イベントの利用」を参照してください。

使用例使用例

SelectionRange を作成し、その Start プロパティと End プロパティを設定し、SelectionRange を MonthCalendar コントロールの SelectionRange プロパティに割り当てるコード例を次に示します。DateChanged イベントが発生すると、Start プロパティおよび End プロパティの値がテキスト ボックスに表示されます。この例は、2 つの TextBox コントロール、Button コントロール、および MonthCalendar コントロールが配置された Form があることを前提にしています。

Visual Basic
Private Sub button1_Click(sender As
 Object, _
  e As EventArgs) Handles button1.Click
   ' Create a SelectionRange object and set its Start and End properties.
   Dim sr As New SelectionRange()
   sr.Start = DateTime.Parse(Me.textBox1.Text)
   sr.End = DateTime.Parse(Me.textBox2.Text)
   ' Assign the SelectionRange object to the
   ' SelectionRange property of the MonthCalendar control. 
   Me.monthCalendar1.SelectionRange = sr
End Sub 


Private Sub monthCalendar1_DateChanged(sender
 As Object, _
  e As DateRangeEventArgs) Handles monthCalendar1.DateChanged
   ' Display the Start and End property values of
   ' the SelectionRange object in the text boxes. 
   Me.textBox1.Text = monthCalendar1.SelectionRange.Start.Date.ToShortDateString()
   Me.textBox2.Text = monthCalendar1.SelectionRange.End.Date.ToShortDateString()
End Sub
C#

    SelectionRange sr = new SelectionRange();

    sr.set_End(DateTime.Parse(this.textBox2.get_Text()));

    /* Assign the SelectionRange object to the

1 暦年を表示する MonthCalendar コントロールが配置されたフォームを表示するコード例を次に示します。BackColor、ForeColor、TitleBackColor、TitleForeColor、CalendarDimensions、TrailingForeColor の各プロパティを設定して、予定表コントロールの外観をカスタマイズする例を次に示します。その他のプロパティ、たとえば AnnuallyBoldedDates、BoldedDates、および MonthlyBoldedDates は、どの日付を太字にするかをカスタマイズするために設定されます。また、予定表の形式を変更するために、FirstDayOfWeek、MaxDate、MinDate、MaxSelectionCount の各プロパティも設定します。DateSelected イベントおよび DateChanged イベントも処理され、ステータスがフォームに表示されます。
