Date Formats

A details explanation about the default date format strings can be found in this MSDN article.

The table below displays a list of the standard format characters supported by RadDateTimePicker. The format characters are case-sensitive; for example, 'f' and 'F' represent different patterns.

Format Character Associated Property/ Description
d ShortDatePattern
D LongDatePattern
f Full date and time (long date and short time)
F FullDateTimePattern (long date and long time)
g General (short date and short time)
G General (short date and long time)
m, M MonthDayPattern
r, R RFC1123Pattern
s SortableDateTimePattern (based on ISO 8601) using local time
t ShortTimePattern
T LongTimePattern
u UniversalSortableDateTimePattern using the format for universal time display
U Full date and time (long date and long time) using universal time

The table below shows a list of patterns that can be combined to create custom patterns. The patterns are case-sensitive; for example, "MM" is recognized, but "mm" is not. If the custom pattern contains white-space characters or characters enclosed in single quotation marks, the output string will also contain those characters. Characters not defined as part of a format pattern or as format characters are reproduced literally.

dd The day of the month. Single-digit days will have a leading zero.
ddd The abbreviated name of the day of the week, as defined in AbbreviatedDayNames.

MM The numeric month. Single-digit months will have a leading zero.

It is possible to define your own format and set the RadDateTimePicker.Format property to Custom . Then, specify the desired CustomFormat, e.g. "dd/MM/yyyy".

this.radDateTimePicker1.Format = DateTimePickerFormat.Custom;
this.radDateTimePicker1.CustomFormat = "yyyy/MM/dd";

Me.radDateTimePicker1.Format = DateTimePickerFormat.Custom
Me.radDateTimePicker1.CustomFormat = "yyyy/MM/dd"
