How to use MonthCalender to insert date in text box?

Question

I have a textBox1 in my windows form. I would like to use it to get date from the user. I want to show MonthCalender1 once the user put the cursor in the textbox1 and then set the date in the textbox1 automatically and then the calender will disappear. How can I use C# or C++/CLI to do that?

This is not the best code, but I hope you get the idea:

public Form1()
{
    InitializeComponent();
    monthCalendar1.MaxSelectionCount = 1;
}

private void textBox1_Enter(object sender, EventArgs e)
{
    monthCalendar1.Visible = true;
}

private void textBox1_Leave(object sender, EventArgs e)
{
    if (!monthCalendar1.Focused)
        monthCalendar1.Visible = false;
}

private void monthCalendar1_DateSelected(object sender, DateRangeEventArgs e)
{
    var monthCalendar = sender as MonthCalendar;
    textBox1.Text = monthCalendar.SelectionStart.ToString();
}

private void monthCalendar1_Leave(object sender, EventArgs e)
{
    var monthCalendar = sender as MonthCalendar;
    monthCalendar.Visible = false;
}

First, you set the MaxSelectionCount for you monthCalendar control. Next, you adding event listeners for leaving focus and gaining focus. If you don't get it working, I can provide sample solution where I tested it.
