Specifying a Culture

The RadTimePicker control supports the System.Globalization namespace. This namespace consists of classes (CompareInfo, CultureInfo, RegionInfo, etc.) that contain culture-related information such as the language, country/region, sort order for strings, calendars in use, and format patterns for dates, currency, and numbers. They are useful classes for writing internationalized applications.

RadTimePicker supports all the cultures in the System.Globalization namespace that are based on the Gregorian calendar.

For East Asian, Middle Eastern and other similar cultures, which have an alternative standard for a different Calendar implementation, RadTimePicker supports their localization and native date and time value representation, but automatically uses the Gregorian calendar internally.


The CultureInfo class represents information about a specific culture including the names of the culture, the writing system, and the calendar used, as well as access to culture-specific objects that provide information for common operations, such as formatting dates and sorting strings.

The culture names follow the RFC 1766 standard in the format "-", where is a lowercase two-letter code derived from ISO 639-1 and is an uppercase two-letter code derived from ISO 3166. For example, U.S. English is "en-US".

All RadTimePicker control lets you associate a CultureInfo object with the control to govern the formatting and parsing of date and time values. To do this you need to set the Culture property of RadTimePicker.

On RadTimePicker you can assign a separate CultureInfo object to the embedded popup time view control by setting the Culture property for it.

The associated CultureInfo object controls:

  • The default format for date and time values that the control displays. You can override this pattern by specifying a date format pattern as the value of the following properties:

    • On RadTimePicker - the DateFormat and DisplayDateFormat properties of the embedded RadDateInput control (accessed through the DateInput property).

    • On RadTimePicker - the TimeFormat property of the embedded RadTimeView control (accessed through the TimeView property).

  • The way RadTimePicker parses values that the user types into the input area.

Assigning the culture declaratively

You can assign the culture of a RadTimePicker control declaratively in the source:

    Culture="French (France)">

Assigning the culture in the code-behind

You can assign a culture property in the code-behind as well:

protected void Page_Load(object sender, EventArgs e)
    RadTimePicker1.Culture = new System.Globalization.CultureInfo("fr-FR", true);
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    RadTimePicker1.Culture = New System.Globalization.CultureInfo("fr-FR", True)
End Sub
