Localization

To localize RadCommandBar to display control text and messages in a specific language:

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

• Start by creating a descendant of the CommandBarLocalizationProvider 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:

public class MyEnglishCommandBarLocalizationProvider : CommandBarLocalizationProvider
{
    public override string GetLocalizedString(string id)
    {
        switch (id)
        {
            case CommandBarStringId.CustomizeDialogChooseToolstripLabelText: return "Choose a toolstrip to rearrange:";
            case CommandBarStringId.CustomizeDialogCloseButtonText: return "Close";
            case CommandBarStringId.CustomizeDialogItemsPageTitle: return "Items";
            case CommandBarStringId.CustomizeDialogMoveDownButtonText: return "Move Down";
            case CommandBarStringId.CustomizeDialogMoveUpButtonText: return "Move Up";
            case CommandBarStringId.CustomizeDialogResetButtonText: return "Reset";
            case CommandBarStringId.CustomizeDialogTitle: return "Customize1";
            case CommandBarStringId.CustomizeDialogToolstripsPageTitle: return "Toolstrips";
            case CommandBarStringId.OverflowMenuAddOrRemoveButtonsText: return "Add or Remove Buttons";
            case CommandBarStringId.OverflowMenuCustomizeText: return "Customize...";
            case CommandBarStringId.ContextMenuCustomizeText: return "Customize...";
            default: return base.GetLocalizedString(id);
        }
    }
}

Public Class MyEnglishCommandBarLocalizationProvider
    Inherits CommandBarLocalizationProvider
    Public Overrides Function GetLocalizedString(ByVal id As String) As String
        Select Case id
            Case CommandBarStringId.CustomizeDialogChooseToolstripLabelText : Return "Choose a toolstrip to rearrange:"
            Case CommandBarStringId.CustomizeDialogCloseButtonText : Return "Close"
            Case CommandBarStringId.CustomizeDialogItemsPageTitle : Return "Items"
            Case CommandBarStringId.CustomizeDialogMoveDownButtonText : Return "Move Down"
            Case CommandBarStringId.CustomizeDialogMoveUpButtonText : Return "Move Up"
            Case CommandBarStringId.CustomizeDialogResetButtonText : Return "Reset"
            Case CommandBarStringId.CustomizeDialogTitle : Return "Customize1"
            Case CommandBarStringId.CustomizeDialogToolstripsPageTitle : Return "Toolstrips"
            Case CommandBarStringId.OverflowMenuAddOrRemoveButtonsText : Return "Add or Remove Buttons"
            Case CommandBarStringId.OverflowMenuCustomizeText : Return "Customize..."
            Case CommandBarStringId.ContextMenuCustomizeText : Return "Customize..."
            Case Else : Return MyBase.GetLocalizedString(id)
        End Select
        Return String.Empty
    End Function
End Class

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

Assigning the Current Localization Provider

CommandBarLocalizationProvider.CurrentProvider = new MyEnglishCommandBarLocalizationProvider();

CommandBarLocalizationProvider.CurrentProvider = New MyEnglishCommandBarLocalizationProvider()

The code provided above illustrates the approach to be used to localize the RadCommandBar and is not intended as a full translation.
