Contoh
Contoh kode berikut membuat SelectionRange, mengatur properti dan End , Start dan menetapkan SelectionRange ke SelectionRange properti MonthCalendar kontrol. DateChanged Saat peristiwa dimunculkan, Start nilai properti dan End ditampilkan dalam kotak teks. Contoh ini mengharuskan Anda memiliki Form dengan dua TextBox kontrol, Button, dan MonthCalendar kontrol.
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
Contoh kode berikut menampilkan formulir yang MonthCalendar berisi kontrol yang menampilkan satu tahun kalender. Contoh menunjukkan pengaturan BackColorproperti , , ForeColorTitleBackColor, TitleForeColor, CalendarDimensionsdan TrailingForeColor untuk menyesuaikan tampilan kontrol kalender. Properti lain seperti AnnuallyBoldedDates, BoldedDates, dan MonthlyBoldedDates diatur untuk menyesuaikan tanggal mana yang dibalur.
