Gets or sets the custom date/time format string.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
To display string literals that contain date and time separators or to format strings, you must use escape characters in the substring. For example, to display the date as "June 15 at 12:00 PM", set the property to "MMMM dd 'at' t:mm tt". If the "at" substring is not enclosed by escape characters, the result is "June 15 aP 12:00PM" because the "t" character is read as the one-letter A.M./P.M. format string (see the format string table below).
The format strings can be combined to format the date and time. For example, to display the date and time as 06/15/2001 12:00 PM, this property should be set to "MM'/'dd'/'yyyy hh':'mm tt". For more information, see Date and Time Format Strings.
The following table lists all the valid format strings and their descriptions.
