To localize RadTimeSpanPicker to display any text and messages in a specific language:

  • All required classes for localization are defined in Telerik.WinControls.UI.Localization namespace.

  • Start by creating a descendant of the RadTimeSpanPickerLocalizationProvider class.

  • Override the GetLocalizedString(string id) method and provide a translation for the label and user messages. If a translation is not provided, the default value will be returned. This behavior is guaranteed by the call to the base GetLocalizedString method in the default clause of the switch statement in the example.

Below is a sample implementation of an English localization provider:

class MyRadTimeSpanPickerLocalizationProvider : RadTimeSpanPickerLocalizationProvider
    public override string GetLocalizedString(string id)
        switch (id)
            case RadTimeSpanPickerStringId.NullText: return "Select time span";
            case RadTimeSpanPickerStringId.DaysText: return "Days";
            case RadTimeSpanPickerStringId.HoursText: return "Hours";
            case RadTimeSpanPickerStringId.MinutesText: return "Minutes";
            case RadTimeSpanPickerStringId.SecondsText: return "Seconds";
            case RadTimeSpanPickerStringId.MillisecondsText: return "Milliseconds";
            case RadTimeSpanPickerStringId.CloseButtonText: return "Close";
        return base.GetLocalizedString(id);

Friend Class MyRadTimeSpanPickerLocalizationProvider
    Inherits RadTimeSpanPickerLocalizationProvider
    Public Overrides Function GetLocalizedString(ByVal id As String) As String
        Select Case id
            Case RadTimeSpanPickerStringId.NullText
                Return "Select time span"
            Case RadTimeSpanPickerStringId.DaysText
                Return "Days"
            Case RadTimeSpanPickerStringId.HoursText
                Return "Hours"
            Case RadTimeSpanPickerStringId.MinutesText
                Return "Minutes"
            Case RadTimeSpanPickerStringId.SecondsText
                Return "Seconds"
            Case RadTimeSpanPickerStringId.MillisecondsText
                Return "Milliseconds"
            Case RadTimeSpanPickerStringId.CloseButtonText
                Return "Close"
        End Select
        Return MyBase.GetLocalizedString(id)
    End Function
End Class

To apply the custom localization provider, instantiate and assign it to the current localization provider:

Assigning the Current Localization Provider

RadTimeSpanPickerLocalizationProvider.CurrentProvider = new MyRadTimeSpanPickerLocalizationProvider();

RadTimeSpanPickerLocalizationProvider.CurrentProvider = New MyRadTimeSpanPickerLocalizationProvider()
