C＃XAML Flyout更改headerbackground顏色

Question

我在C＃中用XAML做了一個彈出窗口，現在我想更改爲標題和返回按鈕保留的空間背景顏色。但該區域未在彈出頁面中定義。有誰知道我可以如何改變圍繞標題和後退按鈕的面板的背景顏色？

你只需要添加HeaderBackground等;

<SettingsFlyout 
x:Class="CatalogApp.FlyoutControl.Login" 
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
xmlns:local="using:CatalogApp.FlyoutControl" 
xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
mc:Ignorable="d" 
IconSource="Assets/SmallLogo.png" 
Title="Login" 
d:DesignWidth="346" 
HeaderBackground="Green">
