Codeplex:SilverlightのWPF DataGridテーマからダウンロードしたように、WhistlerBlue.xamlリソースディクショナリを使用してスタイル設定されたListViewがあります。
交互の(奇数と偶数の)行の背景色を変えたい。
次のコードをデフォルトのWhistlerBlueListViewItem
スタイル( ControlTemplate.Triggers
セクション内)に追加しました。
<Trigger Property="ItemsControl.AlternationIndex" Value="0">
<Setter Property="Background" Value="White"></Setter>
</Trigger>
<Trigger Property="ItemsControl.AlternationIndex" Value="1">
<Setter Property="Background" Value="AliceBlue"></Setter>
</Trigger>
ListViewスタイルのAlternatingCount
プロパティもに設定しまし2
たが、交互のスタイルトリガーがまだ機能していません。
任意のポインタをいただければ幸いです。
以下に完全なListViewItemStyleを貼り付けました。
