Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public DateTimePickerFormat Format { get; set; }

Property Value

Type: System.Windows.Forms.DateTimePickerFormat

One of the DateTimePickerFormat values. The default is Long.

Exception Condition

The value assigned is not one of the DateTimePickerFormat values.

This property determines the date/time format the date is displayed in. The date/time format is based on the user's regional settings in their operating system.


The Format property must be set to DateTimePickerFormat.Custom for the CustomFormat property to affect the formatting of the displayed date and time.

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

The following code example sets the CustomFormat property so that the DateTimePicker will display the date as "June 01, 2001 - Friday". This code assumes that an instance of a DateTimePicker control has been created on a Form.

public void SetMyCustomFormat()
   // Set the Format type and the CustomFormat string.
   dateTimePicker1.Format = DateTimePickerFormat.Custom;
   dateTimePicker1.CustomFormat = "MMMM dd, yyyy - dddd";
