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. |

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"
