グリッドにデータCRUDインラインを作成します。 Createメソッドは正常に終了しました。しかし、私が更新しようとすると、常に新しいデータが作成されます。私はデバッグしようとするとき。常にcreateメソッドに移動します。誰か助けてください。私はKendoUI、MVC4をC＃で使用しています。高度な剣道グリッドのデータを更新できませんでした。常にデータを作成してください。
モデルのおかげで

が機能しませんでした。それでも新しいデータが作成されます。更新に失敗しました –
私は前に気付きませんでしたが、 'update'イベント' events.RequestEnd（ "force_update"）;を無効にしようとしました。これはデータソースに干渉している可能性があります。 –
