MouseEnter, Mouseleave 이벤트를 ExpanderView에 사용하십시오.

<toolkit:ExpanderView x:Name="Header3" FontSize="22" Foreground="Black" Expanded="Header3_Expanded" MouseEnter="Header_MouseEnter" MouseLeave="Header_MouseLeave">

. 백엔드의

다음 코드를 씁니다

    private void Header_MouseEnter(object sender, MouseEventArgs e)
    {
        SolidColorBrush sb = new SolidColorBrush();
        sb.Color = Color.FromArgb(170, 170, 170, 170);
        WhattodoGrid.Background = sb;
    }
    private void Header_MouseLeave(object sender, MouseEventArgs e)
    {
        SolidColorBrush sb = new SolidColorBrush();
        sb.Color = Color.FromArgb(0,0,0,0);
        WhattodoGrid.Background = sb;
    }
