windows - windows phone 7中带有注销按钮的标题

Question

我是 Windows Phone 开发的新手。

我需要带有注销按钮的自定义标题，然后在每个页面上使用它。我怎样才能实现这一点？

Answer 1

首先，Logout在应用程序的每个页面的标题中都有一个按钮并不是一个好主意。我建议您ApplicationBar用于此目的并在那里添加一个 logout MenuItem。主要思想是注销操作不经常使用，所以隐藏了。并将您的注销逻辑添加到基PhoneApplicationPage类或基ViewModel类。如果使用 anApplicationBar不适合您，您可以使用UserControl并将其添加到每个应用程序页面。标题示例UserControl

<UserControl x:Class="PhoneApp3.LogoutUserControl"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    FontFamily="{StaticResource PhoneFontFamilyNormal}"
    FontSize="{StaticResource PhoneFontSizeNormal}"
    Foreground="{StaticResource PhoneForegroundBrush}"
    d:DesignHeight="480" d:DesignWidth="480">

    <Grid x:Name="LayoutRoot" Background="{StaticResource PhoneChromeBrush}">
        <StackPanel>
            <Image Source="/Images/Header.jpg"/>
            <Button Click="Logout" Content="Logout"/>
        </StackPanel>
    </Grid>
</UserControl>

你的主页看起来像

   <phone:PhoneApplicationPage
    x:Class="PhoneApp3.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
    xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:userControls="clr-namespace:PhoneApp3"
    mc:Ignorable="d"
    FontFamily="{StaticResource PhoneFontFamilyNormal}"
    FontSize="{StaticResource PhoneFontSizeNormal}"
    Foreground="{StaticResource PhoneForegroundBrush}"
    SupportedOrientations="Portrait" Orientation="Portrait"
    shell:SystemTray.IsVisible="True">
    <!--LayoutRoot is the root grid where all page content is placed-->
    <Grid x:Name="LayoutRoot" Background="Transparent">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
            <userControls:LogoutUserControl Grid.Row="0" x:Name="HeaderControl"/>
            <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
        </Grid>
    </Grid>
</phone:PhoneApplicationPage>
