FileSavePicker光在主题上的C＃窗口地铁应用 [英] FileSavePicker in Light theme on C# windows metro App

问题描述

我不知道如何改变FileSavePicker为主题的地铁应用程序。我只找到这个问题的答案为Android和它并没有帮助这么多。我没有发现MSDN文档任何东西。 那么，有可能改变一个FileSavePicker的主题？是否存在一个方法或属性，如fileSavePicker.RequestedTheme（）？

只是信息我定义我的应用程序的主题App.xaml中：

 ＆lt;应用
    X：类=ClientAirNavLight_WS.App
    的xmlns =htt​​p://schemas.microsoft.com/winfx/2006/xaml/$p$psentation
    的xmlns：X =htt​​p://schemas.microsoft.com/winfx/2006/xaml
    XMLNS：地方=使用：ClientAirNavLight_WS
    RequestedTheme =轻＆GT;

    ＆LT; Application.Resources＆GT;

        ＆LT;的ResourceDictionary＆GT;
            ＆LT; ResourceDictionary.MergedDictionaries＆GT;

                ＆LT;！ - 
                    定义的平台外观通用特性，手感风格
                    通过Visual Studio项目和项模板所需
                  - ＆GT;
                ＆LT; ResourceDictionary中源=通用/ StandardStyles.xaml/＆GT;
            ＆LT; /ResourceDictionary.MergedDictionaries>

        ＆LT; / ResourceDictionary中＆GT;
    ＆LT; /Application.Resources>
＆LT; /用途＆gt;
 

解决方案

在FileSavePicker的颜色是由用户的主题preferences定义的，而不是由你的应用程序。它不能被StandardStyles.xaml修改

为了你的应用程序不能尝试和模拟系统对话框（如FileSavePicker）您的应用程序不能访问这些用户preferences。

I was wondering how to change the theme of FileSavePicker on a metro app. I only found answer to this question for android and it didn't help so much. And I didn't find anything in msdn documentation. So is it possible to change the theme of a FileSavePicker? Does it exist a method or property such as fileSavePicker.RequestedTheme() ?

Just for information I defined my application's theme in App.xaml :

<Application
    x:Class="ClientAirNavLight_WS.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:ClientAirNavLight_WS"
    RequestedTheme="Light">

    <Application.Resources>

        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>

                <!-- 
                    Styles that define common aspects of the platform look and feel
                    Required by Visual Studio project and item templates
                 -->
                <ResourceDictionary Source="Common/StandardStyles.xaml"/>
            </ResourceDictionary.MergedDictionaries>

        </ResourceDictionary>
    </Application.Resources>
</Application>

解决方案

The FileSavePicker colours are defined by the user's theme preferences, not by your application. It cannot be modified by StandardStyles.xaml.

In order that your app can't try and impersonate a system dialog (like FileSavePicker) your application doesn't have access to those user preferences.
