How to use MonthCalender to insert date in text box?

问题

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.

If you want to get Date from a month calender and display it in text box, then first of all drag and drop monthCalender from ToolBox in Visual Studio to your design form. and double click on it and write these code

  private void monthCalendar1_DateChanged(object sender, DateRangeEventArgs e)
    {
       textbox1.text = monthCalendar1.SelectionRange.Start.ToShortDateString();
    }

This will display a date like this 14/2/2014
