Contoh

Contoh berikut membuat objek SelectionRange, mengatur properti Start dan End, dan menetapkan objek SelectionRange ke properti SelectionRange kontrol MonthCalendar. Saat peristiwa DateChanged dinaikkan, nilai properti Start dan End ditampilkan dalam kotak teks. Contoh ini mengasumsikan bahwa Anda memiliki Form dengan dua kontrol TextBox, Button, dan kontrol MonthCalendar.

private:
   void button1_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {
      // Create a SelectionRange object and set its Start and End properties.
      SelectionRange^ sr = gcnew SelectionRange;
      sr->Start = DateTime::Parse( this->textBox1->Text );
      sr->End = DateTime::Parse( this->textBox2->Text );
      
      /* Assign the SelectionRange object to the
            SelectionRange property of the MonthCalendar control. */
      this->monthCalendar1->SelectionRange = sr;
   }

   void monthCalendar1_DateChanged( Object^ /*sender*/, DateRangeEventArgs^ /*e*/ )
   {
      /* Display the Start and End property values of
            the SelectionRange object in the text boxes. */
      this->textBox1->Text = monthCalendar1->SelectionRange->Start.Date.ToShortDateString();
      this->textBox2->Text = monthCalendar1->SelectionRange->End.Date.ToShortDateString();
   }

private void button1_Click(object sender, System.EventArgs e)
{
   // Create a SelectionRange object and set its Start and End properties.
   SelectionRange sr = new SelectionRange();
   sr.Start = DateTime.Parse(this.textBox1.Text);
   sr.End = DateTime.Parse(this.textBox2.Text);
   /* Assign the SelectionRange object to the 
      SelectionRange property of the MonthCalendar control. */
   this.monthCalendar1.SelectionRange = sr;
}

private void monthCalendar1_DateChanged(object sender, DateRangeEventArgs e)
{
   /* Display the Start and End property values of 
      the SelectionRange object in the text boxes. */
   this.textBox1.Text = 
     monthCalendar1.SelectionRange.Start.Date.ToShortDateString();
   this.textBox2.Text = 
     monthCalendar1.SelectionRange.End.Date.ToShortDateString();
}

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

Keterangan

Nilai Start dan End diatur ke null saat konstruktor ini digunakan.

SelectionRange(DateTime, DateTime)

Sumber:

SelectionRange.cs

Menginisialisasi instans baru kelas SelectionRange dengan tanggal awal dan akhir yang ditentukan.

public:
 SelectionRange(DateTime lower, DateTime upper);

public SelectionRange(DateTime lower, DateTime upper);

new System.Windows.Forms.SelectionRange : DateTime * DateTime -> System.Windows.Forms.SelectionRange

Public Sub New (lower As DateTime, upper As DateTime)

Parameter

lower

DateTime

Tanggal mulai dalam SelectionRange.

upper

DateTime

Tanggal akhir dalam SelectionRange.

Contoh

Contoh berikut mengatur properti SelectionRange kontrol MonthCalendar berdasarkan dua tanggal yang dimasukkan ke dalam dua kontrol TextBox saat Button diklik. Kode ini mengasumsikan instans baru kontrol MonthCalendar, dua kontrol TextBox, dan Button telah dibuat pada Form. Anda mungkin mempertimbangkan untuk menambahkan kode untuk memvalidasi Text yang ditetapkan ke kotak teks untuk memverifikasi bahwa kode tersebut berisi tanggal yang valid.

private:
   void button1_Click( Object^ sender, EventArgs^ e )
   {
      // Set the SelectionRange with start and end dates from text boxes.
      try
      {
         monthCalendar1->SelectionRange = gcnew SelectionRange(
            DateTime::Parse( textBox1->Text ),
            DateTime::Parse( textBox2->Text ) );
      }
      catch ( Exception^ ex ) 
      {
         MessageBox::Show( ex->Message );
      }
   }

private void button1_Click(object sender,
                           EventArgs e)
{
   // Set the SelectionRange with start and end dates from text boxes.
   try
   {
      monthCalendar1.SelectionRange = new SelectionRange(
        DateTime.Parse(textBox1.Text),
        DateTime.Parse(textBox2.Text));
   }
   catch(Exception ex)
   {
      MessageBox.Show(ex.Message);
   }
}

Private Sub button1_Click(sender As Object, e As EventArgs)
   ' Set the SelectionRange with start and end dates from text boxes.
   Try
      monthCalendar1.SelectionRange = New SelectionRange( _
        DateTime.Parse(textBox1.Text), _
        DateTime.Parse(textBox2.Text))
   Catch ex As Exception
      MessageBox.Show(ex.Message)
   End Try
End Sub

Keterangan

Nota

Jika nilai lowerDateTime lebih besar dari nilai upperDateTime, nilai lower akan ditetapkan ke properti End alih-alih properti Start.
