DatePickerにフォーカスが当たったときに背景色を変更する

Posted at 2024-02-07

単純に

IsFocusedでは駄目だった

実装

IsKeyboardFocusWithinを使えばOK！

xaml

<Style TargetType="DatePicker">   
    <Style.Triggers>
        <Trigger Property="IsKeyboardFocusWithin" Value="True">
            <Setter Property="Background" Value="#ffef85"/>
        </Trigger>
    </Style.Triggers>
</Style>

感謝
