Format datetimepicker date

In datetimepicker, select format as cutstom, and then write the format string in cutstomformat. The introduction is as follows:

How do you display am? It is written as: hh: Mm TT (case sensitive)
To display a string or format string containing the date and time delimiters, you must use an escape character in the substring. For example, to display the date as "June 06 at PM", set the customformat attribute to "Mmmm dd' at 't: Mm TT ". If the escape character does not contain the "at" substring, the result is "June 06 ap pm ", because the character "T" is read as a single letter AM/PM Format String (see Format 1 below) string table ).
Format String that can be combined to set the date and time format. For example, to display the date and time as PM on 06/01/2001, set this attribute to "dd'/'mm'/'yyyy hh': 'Mm TT ". For more information, see date and time format strings.
