XAMLを初めて使用していて、機能を使いこなしています。この段階で、私は静的データを持つデータグリッドを作成しています。私は特定の行を無効にする方法を知りたいSilverlightプロパティを項目値にバインドする方法
、私がモデルにでIsEnabledプロパティを結合して、それをそのようなブール値を与えてみました：

public Model(int id, string name, string prop, bool isenabled)
{
Id = id;

Prop = prop;

}
protected virtual void OnPropertyChanged(string propertyName)
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
}
}
これまでのところ、IsEnabledの列は予期したとおりに追加されていましたが、プロパティ値も設定されていると思いました。
このようにXAMLとC＃の間のバインディングがどのように機能するのか誰かが説明できるのでしょうか？
