Localization

Updated over 6 months ago

To localize RadTabbedForm 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 RadTabbedFormControlLocalizationProvider 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:

C#

class MyRadTabbedFormControlLocalizationProvider : RadTabbedFormControlLocalizationProvider
{
    public override string GetLocalizedString(string id)
    {
        switch (id)
        {
            case RadTabbedFormControlStringId.NewTabMenuTtem: return "New tab";
            case RadTabbedFormControlStringId.PinTabMenuTtem: return "Pin tab";
            case RadTabbedFormControlStringId.CloseTabMenuTtem: return "Close tab";
            case RadTabbedFormControlStringId.CloseOtherTabsMenuTtem: return "Close other tabs";
            case RadTabbedFormControlStringId.CloseRightTabsMenuTtem: return "Close tabs to the right";
            case RadTabbedFormControlStringId.UnpinTabMenuTtem: return "Unpin tab";
        }
        return base.GetLocalizedString(id);
    }
}

VB.NET

Friend Class MyRadTabbedFormControlLocalizationProvider
    Inherits RadTabbedFormControlLocalizationProvider
    Public Overrides Function GetLocalizedString(ByVal id As String) As String
        Select Case id
            Case RadTabbedFormControlStringId.NewTabMenuTtem
                Return "New tab"
            Case RadTabbedFormControlStringId.PinTabMenuTtem
                Return "Pin tab"
            Case RadTabbedFormControlStringId.CloseTabMenuTtem
                Return "Close tab"
            Case RadTabbedFormControlStringId.CloseOtherTabsMenuTtem
                Return "Close other tabs"
            Case RadTabbedFormControlStringId.CloseRightTabsMenuTtem
                Return "Close tabs to the right"
            Case RadTabbedFormControlStringId.UnpinTabMenuTtem
                Return "Unpin tab"
        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

C#

RadTabbedFormControlLocalizationProvider.CurrentProvider = new MyRadTabbedFormControlLocalizationProvider();

VB.NET

RadTabbedFormControlLocalizationProvider.CurrentProvider = New MyRadTabbedFormControlLocalizationProvider()
