private void textBox1_Click(object sender, EventArgs e)
{
monthCalendar1.Show();
}
private void Form1_Load(object sender, EventArgs e)
{
monthCalendar1.Hide();
}
private void monthCalendar1_DateSelected(object sender, DateRangeEventArgs e)
{
textBox489.Text = monthCalendar1.SelectionEnd.ToString();
monthCalendar1.Hide();
}
基本实现你说的功能了!!
