To localize RadSyntaxEditor to display control 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 RadSyntaxEditorLocalizationProvider 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 of the base GetLocalizedString method in the default clause of the switch statement in the example.

Localizing RadSyntaxEditor Strings

public class EnglishRadSyntaxEditorLocalizationProvider : RadSyntaxEditorLocalizationProvider
    public override string GetLocalizedString(string id)
        switch (id)
            case RadSyntaxEditorStringId.FindTextBox: return "Find...";
            case RadSyntaxEditorStringId.ReplaceTextBox: return "Replace...";
            case RadSyntaxEditorStringId.FindPrevious: return "Find Previous (Shift + F3)";
            case RadSyntaxEditorStringId.FindNext: return "Find Next (F3)";
            case RadSyntaxEditorStringId.FindAll: return "Find All";
            case RadSyntaxEditorStringId.Replace: return "Replace";
            case RadSyntaxEditorStringId.ReplaceAll: return "Replace All";
        return base.GetLocalizedString(id);

Public Class EnglishRadSyntaxEditorLocalizationProvider
    Inherits RadSyntaxEditorLocalizationProvider
    Public Overrides Function GetLocalizedString(ByVal id As String) As String
        Select Case id
            Case RadSyntaxEditorStringId.FindTextBox
                Return "Find..."
            Case RadSyntaxEditorStringId.ReplaceTextBox
                Return "Replace..."
            Case RadSyntaxEditorStringId.FindPrevious
                Return "Find Previous (Shift + F3)"
            Case RadSyntaxEditorStringId.FindNext
                Return "Find Next (F3)"
            Case RadSyntaxEditorStringId.FindAll
                Return "Find All"
            Case RadSyntaxEditorStringId.Replace
                Return "Replace"
            Case RadSyntaxEditorStringId.ReplaceAll
                Return "Replace All"
        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

RadSyntaxEditorLocalizationProvider.CurrentProvider = new EnglishRadSyntaxEditorLocalizationProvider();

RadSyntaxEditorLocalizationProvider.CurrentProvider = New EnglishRadSyntaxEditorLocalizationProvider()

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