ListViewItem が選択されているときにその色を変更しようとしています。デフォルトの色は Windows 8 の紫色です。
私の App.xaml では、次の行を設定できます。これにより、アプリケーション全体の ListViews の選択された色が変更されます。
<SolidColorBrush x:Key="ListViewItemSelectedBackgroundThemeBrush" Color="Orange" />
ただし、これをページ単位で行いたいので、これをページリソースに設定したいと思います。
ただし、これを試してみると、無視され、使用されません。app.xaml からのみ動作するようです。
どうすればこれを回避できるか知っている人はいますか？
これは、XAML と C# で記述された Windows 8 ストア アプリ用です。
ありがとう
Visual Studio xaml デザイナーでは、アウトライン ウィンドウに移動し、ツリーの ListView を右クリックして、[追加テンプレートの編集] > [アイテム コンテナー スタイルの編集] > [コピーの編集] をクリックします。ListViewItem スタイルのコピーが生成され、このスタイルの ListViewItemSelectedBackgroundThemeBrush を任意の色に置き換えることができます。
変更する必要がある色が 1 つだけの場合は、その色に Tag プロパティを使用できます。このように、それぞれ異なる色のページが多数ある場合、各ページにスタイル全体を含める必要はありません。
次に例を示し
ます。 App.xaml で定義する選択色としてタグを使用する ListViewItem スタイル:

そして、各ページで、次のようにスタイルを定義するだけです:
<Style x:Key="OrangeListViewItemStyle" TargetType="ListViewItem" BasedOn="{StaticResource TagListViewItemStyle}">
<Setter Property="Tag">

<SolidColorBrush Color="Orange"/>
</Setter.Value>
</Setter>

定義する必要がある色が複数ある場合は、いくつかの添付プロパティを追加することで同じ原則を使用できます。
