wpfでMVVmを使ったアプリを開発しています。ここでは、ユーザー コントロールを別のユーザー コントロールに配置する必要があります。

メイン ユーザー コントロールには、情報を保存するための UI 要素があります。さらに、リスト ビューがある場所にユーザー コントロールを配置する必要があります。リスト ビューにデータを入力する必要があります。

XAMLは次のとおりです

エントリ usercontrol に Listview の Usercontrol への参照を追加し、 Datacontext を設定します。お気に入り-

< StackPanel>

< views:ExceptionStrip DataContext="{Binding ExceptionViewModel}"/>
