Examples

The following code example creates an new instance of a DateTimePicker control and initializes it. The control's CustomFormat property is set. Also, the ShowCheckBox property is set so that the control displays a CheckBox, and the ShowUpDown property is set so that the control is displayed as a spin button control.

public:
   void CreateMyDateTimePicker()
   {
      // Create a new DateTimePicker control and initialize it.
      DateTimePicker^ dateTimePicker1 = gcnew DateTimePicker;
      
      // Set the MinDate and MaxDate.
      dateTimePicker1->MinDate = DateTime(1985,6,20);
      dateTimePicker1->MaxDate = DateTime::Today;
      
      // Set the CustomFormat string.
      dateTimePicker1->CustomFormat = "MMMM dd, yyyy - dddd";
      dateTimePicker1->Format = DateTimePickerFormat::Custom;
      
      // Show the CheckBox and display the control as an up-down control.
      dateTimePicker1->ShowCheckBox = true;
      dateTimePicker1->ShowUpDown = true;
   }

public void CreateMyDateTimePicker()
{
   // Create a new DateTimePicker control and initialize it.
   DateTimePicker dateTimePicker1 = new DateTimePicker();

   // Set the MinDate and MaxDate.
   dateTimePicker1.MinDate = new DateTime(1985, 6, 20);
   dateTimePicker1.MaxDate = DateTime.Today;

   // Set the CustomFormat string.
   dateTimePicker1.CustomFormat = "MMMM dd, yyyy - dddd";
   dateTimePicker1.Format = DateTimePickerFormat.Custom;

   // Show the CheckBox and display the control as an up-down control.
   dateTimePicker1.ShowCheckBox = true;
   dateTimePicker1.ShowUpDown = true;
}

Public Sub CreateMyDateTimePicker()
    ' Create a new DateTimePicker control and initialize it.
    Dim dateTimePicker1 As New DateTimePicker()
    
    ' Set the MinDate and MaxDate.
    dateTimePicker1.MinDate = New DateTime(1985, 6, 20)
    dateTimePicker1.MaxDate = DateTime.Today
    
    ' Set the CustomFormat string.
    dateTimePicker1.CustomFormat = "MMMM dd, yyyy - dddd"
    dateTimePicker1.Format = DateTimePickerFormat.Custom
    
    ' Show the CheckBox and display the control as an up-down control.
    dateTimePicker1.ShowCheckBox = True
    dateTimePicker1.ShowUpDown = True
End Sub

Remarks

When the ShowUpDown property is set to true, a spin button control (also known as an up-down control), rather than a drop-down calendar, is used to adjust time values. The date and time can be adjusted by selecting each element individually and using the up and down buttons to change the value.

To display only time in a DateTimePicker, set the Format property to Time, and the ShowUpDown property to true.
