Windows 窗体组件 > 公共概念 > 示例 > 如何： 通过修改默认资源来本地化 DevExpress 控件

下面的示例演示了如何把 XtraGrid 控件和 XtraEditors 库 的用户界面本地化为德语。 要执行此操作，需要创建有本地化资源字符串的 DevExpress.XtraGrid.Localization.GridLocalizer 和 Localizer 类的子类。

public class GermanGridLocalizer : GridLocalizer {
   public override string Language { get { return "Deutsch"; }}
   public override string GetLocalizedString(GridStringId id) {
      string ret = "";
      switch(id) {
         // ...
         case GridStringId.MenuColumnSortAscending : return "Aufsteigend sortieren"; 
         case GridStringId.MenuColumnSortDescending : return "Absteigend sortieren"; 
         case GridStringId.MenuColumnGroup : return "Gruppieren fur dieses Feld"; 
         case GridStringId.MenuColumnUnGroup : return "Gruppierung aufheben"; 
         case GridStringId.MenuColumnColumnCustomization : 
             return "Laufzeit benutzerdefinierte Spalte"; 
         case GridStringId.MenuColumnBestFit : return "Optimale Breite"; 
         case GridStringId.MenuColumnFilter : return "Kann gruppieren"; 
         case GridStringId.MenuColumnClearFilter : return "Filter aufheben"; 
         case GridStringId.MenuColumnBestFitAllColumns : return "Optimale Breite (alle Spalten)";
         // ...
         default:
            ret = "";
            break;
      }
      return ret;
   }
}

public class GermanEditorsLocalizer : Localizer {
   public override string Language { get { return "Deutsch"; }}
   public override string GetLocalizedString(StringId id) {
      switch(id) {
         // ...
         case StringId.NavigatorTextStringFormat: return "Zeile {0} von {1}";
         case StringId.PictureEditMenuCut: return "Ausschneiden";
         case StringId.PictureEditMenuCopy: return "Kopieren";
         case StringId.PictureEditMenuPaste: return "Einfugen";
         case StringId.PictureEditMenuDelete: return "Loschen";
         case StringId.PictureEditMenuLoad: return "Laden";
         case StringId.PictureEditMenuSave: return "Speichern";
         // ...
      }
      return "";
   }
}

Public Class GermanGridLocalizer
   Inherits GridLocalizer
   Public Overrides ReadOnly Property Language() As String
      Get
         Return "Deutsch"
      End Get
   End Property

   Public Overrides Function GetLocalizedString(ByVal id As GridStringId) As String
      Dim ret As String = ""
      Select Case id
         ' ...
         Case GridStringId.MenuColumnSortAscending : Return "Aufsteigend sortieren"
         Case GridStringId.MenuColumnSortDescending : Return "Absteigend sortieren"
         Case GridStringId.MenuColumnGroup : Return "Gruppieren fur dieses Feld"
         Case GridStringId.MenuColumnUnGroup : Return "Gruppierung aufheben"
         Case GridStringId.MenuColumnColumnCustomization : _
              Return "Laufzeit benutzerdefinierte Spalte"
         Case GridStringId.MenuColumnBestFit : Return "Optimale Breite"
         Case GridStringId.MenuColumnFilter : Return "Kann gruppieren"
         Case GridStringId.MenuColumnClearFilter : Return "Filter aufheben"
         Case GridStringId.MenuColumnBestFitAllColumns : Return "Optimale Breite (alle Spalten)"
         ' ...
         Case Else
            ret = ""
      End Select
      Return ret
   End Function
End Class

Public Class GermanEditorsLocalizer
   Inherits Localizer
   Public Overrides ReadOnly Property Language() As String
      Get
         Return "Deutsch"
      End Get
   End Property

   Public Overrides Function GetLocalizedString(ByVal id As StringId) As String
      Select Case id
         ' ...
         Case StringId.NavigatorTextStringFormat : Return "Zeile {0} von {1}"
         Case StringId.PictureEditMenuCut : Return "Ausschneiden"
         Case StringId.PictureEditMenuCopy : Return "Kopieren"
         Case StringId.PictureEditMenuPaste : Return "Einfugen"
         Case StringId.PictureEditMenuDelete : Return "Loschen"
         Case StringId.PictureEditMenuLoad : Return "Laden"
         Case StringId.PictureEditMenuSave : Return "Speichern"
         ' ...
      End Select
      Return ""
   End Function
End Class

然后，这些本地化提供程序被实例化，并被指派到它们祖先的 Active 属性。

C#CopyCode image复制代码
 private void Form1_Load(object sender, System.EventArgs e) {
   GridLocalizer.Active = new GermanGridLocalizer();
   Localizer.Active = new GermanEditorsLocalizer();
}
Visual BasicCopyCode image复制代码
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles MyBase.Load
   GridLocalizer.Active = New GermanGridLocalizer()
   Localizer.Active = New GermanEditorsLocalizer()
End Sub

运行时刻网格控件界面的本地化结果如下所示：
