DateTimePicker Control

The DateTimePicker allows users to select a date and/or time from a calendar dropdown.

What is a DateTimePicker?

DateTimePicker displays a date that users can change by clicking the calendar icon. It can show dates, times, or both. Perfect for birthday selection, appointment booking, and scheduling.

Code Example

// Set properties
dtpBirthday.Format = DateTimePickerFormat.Short;
dtpBirthday.Value = new DateTime(2000, 1, 1);
dtpBirthday.MaxDate = DateTime.Today;

// Get selected date
private void btnSubmit_Click(object sender, EventArgs e)
{
    DateTime selected = dtpBirthday.Value;
    MessageBox.Show($"Selected: {selected.ToShortDateString()}");
}

Exercise

  1. Add a DateTimePicker for birthdate selection.
  2. Add a Button that shows the user's age.
  3. Add a CheckBox to show/hide the time selection.
  4. Display the selected date in a Label.
Key Takeaway

DateTimePicker makes date selection easy and consistent. Use Value to get the selected date as a DateTime.
