作者:webabcd

介绍
与众不同 windows phone 8.1 之 新增控件

  • 概述
  • ContentDialog - 对话框控件
  • MapControl - 又一个地图控件

示例
1、概述
Summary.xaml

<Page
x:Class="Demo.Control.Summary"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:Demo.Control"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"> <Grid>
<StackPanel> <TextBlock TextWrapping="Wrap">
<Run>1、新建 wp 项目时,有了 silverlight 版 wp 和 windows 版 wp 的区别,抛弃 silverlight 吧,以后只会有 Windows Runtime Apps</Run>
<LineBreak />
<Run>2、本系列仅以 windows 版 wp 为例,所有之前写过的与 Windows Store Apps 相关的知识点都不会再写,关于 Windows Store Apps 的知识点请参见《重新想象 Windows 8 Store Apps 系列文章》</Run>
<LineBreak />
<Run>3、大多数控件都是 wp 和 windows 通用的,另外 wp 有一些自己独有的控件,后续会一一说明</Run>
</TextBlock> </StackPanel>
</Grid>
</Page>

2、演示对话框控件的应用
ContentDialogDemo/CustomContentDialog.xaml

<ContentDialog
x:Class="Demo.Control.ContentDialogDemo.CustomContentDialog"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:Demo.Control.ContentDialogDemo"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" Title="custom dialog title"
PrimaryButtonText="primary button"
SecondaryButtonText="secondary button"
PrimaryButtonClick="ContentDialog_PrimaryButtonClick"
SecondaryButtonClick="ContentDialog_SecondaryButtonClick"> <!--以下为自定义对话框的标题-->
<ContentDialog.TitleTemplate>
<DataTemplate>
<TextBlock Text="custom dialog title" Foreground="Red" />
</DataTemplate>
</ContentDialog.TitleTemplate> <!--以下为自定义对话框的内容-->
<StackPanel VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
<TextBox Name="email" Header="Email address"/>
<PasswordBox Name="password" Header="Password"/>
<CheckBox Name="showPassword" Content="Show password"/> <TextBlock Name="body" Style="{StaticResource MessageDialogContentStyle}" TextWrapping="Wrap">
<TextBlock.Text>
content content content content content content content content content content content content content content
</TextBlock.Text>
</TextBlock>
</StackPanel> </ContentDialog>

ContentDialogDemo/CustomContentDialog.xaml.cs

/*
* 自定义 ContentDialog
*/ using Windows.UI.Xaml.Controls; namespace Demo.Control.ContentDialogDemo
{
public sealed partial class CustomContentDialog : ContentDialog
{
public CustomContentDialog()
{
this.InitializeComponent();
} private void ContentDialog_PrimaryButtonClick(ContentDialog sender, ContentDialogButtonClickEventArgs args)
{
// 用户点击了第一个按钮(在对话框的调用者中通过 ContentDialogResult 获取用户的行为)
} private void ContentDialog_SecondaryButtonClick(ContentDialog sender, ContentDialogButtonClickEventArgs args)
{
// 用户点击了第二个按钮(在对话框的调用者中通过 ContentDialogResult 获取用户的行为)
}
}
}

ContentDialogDemo/Demo.xaml

<Page
x:Class="Demo.Control.ContentDialogDemo.Demo"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:Demo.Control.ContentDialogDemo"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"> <Grid>
<StackPanel> <Button Name="btnShowDialog" Content="弹出一个标准的对话框" Click="btnShowDialog_Click" /> <Button Name="btnShowCustomDialog" Content="弹出一个自定义的对话框" Click="btnShowCustomDialog_Click" Margin="0 10 0 0" /> <TextBlock Name="lblMsg" Margin="0 10 0 0" /> </StackPanel>
</Grid>
</Page>

ContentDialogDemo/Demo.xaml.cs

/*
* ContentDialog - 对话框控件(wp only)
* FullSizeDesired - 是否全屏弹出对话框
* Title, TitleTemplate - 对话框的标题(可以自定义样式)
* Content, ContentTemplate - 对话框的内容(可以自定义样式)
* PrimaryButtonText - 对话框第一个按钮显示的文本
* SecondaryButtonText - 对话框第二个按钮显示的文本
* PrimaryButtonCommand, PrimaryButtonCommandParameter, SecondaryButtonCommand, SecondaryButtonCommandParameter - 按钮命令及命令参数
*
* PrimaryButtonClick - 第一个按钮按下时触发的事件
* SecondaryButtonClick - 第二个按钮按下时触发的事件
* Closed, Closing, Opened - 顾名思义的一些事件
*
* ShowAsync() - 弹出对话框
* Hide() - 隐藏对话框
*
*
* 注意:自定义对话框参见 CustomContentDialog.xaml
*/ using System;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls; namespace Demo.Control.ContentDialogDemo
{
public sealed partial class Demo : Page
{
public Demo()
{
this.InitializeComponent();
} private async void btnShowDialog_Click(object sender, RoutedEventArgs e)
{
ContentDialog dialog = new ContentDialog()
{
Title = "dialog title",
Content = "dialog content, dialog content, dialog content, dialog content, dialog content, dialog content, dialog content",
FullSizeDesired = true,
PrimaryButtonText = "PrimaryButton",
SecondaryButtonText = "SecondaryButton"
}; dialog.PrimaryButtonClick += dialog_PrimaryButtonClick;
dialog.SecondaryButtonClick += dialog_SecondaryButtonClick; // 弹出对话框,返回值为用户的选择结果
/*
* ContentDialogResult.Primary - 用户选择了第一个按钮
* ContentDialogResult.Secondary - 用户选择了第二个按钮
* ContentDialogResult.None - 用户没有选择(按了系统的“返回”按钮)
*/
ContentDialogResult result = await dialog.ShowAsync();
if (result == ContentDialogResult.Primary)
{
lblMsg.Text += "选择了第一个按钮\n";
}
else if (result == ContentDialogResult.Secondary)
{
lblMsg.Text += "选择了第二个按钮\n";
}
else if (result == ContentDialogResult.None)
{
lblMsg.Text += "没有选择按钮\n";
}
} void dialog_PrimaryButtonClick(ContentDialog sender, ContentDialogButtonClickEventArgs args)
{
lblMsg.Text += "点击了第一个按钮\n";
} void dialog_SecondaryButtonClick(ContentDialog sender, ContentDialogButtonClickEventArgs args)
{
lblMsg.Text += "点击了第二个按钮\n";
} // 弹出自定义对话框
async private void btnShowCustomDialog_Click(object sender, RoutedEventArgs e)
{
// 实例化自定义对话框
CustomContentDialog contentDialog = new CustomContentDialog(); // 弹出对话框,返回值为用户的选择结果
/*
* ContentDialogResult.Primary - 用户选择了第一个按钮
* ContentDialogResult.Secondary - 用户选择了第二个按钮
* ContentDialogResult.None - 用户没有选择(按了系统的“返回”按钮)
*/
ContentDialogResult result = await contentDialog.ShowAsync();
if (result == ContentDialogResult.Primary)
{
lblMsg.Text += "选择了第一个按钮\n";
}
else if (result == ContentDialogResult.Secondary)
{
lblMsg.Text += "选择了第二个按钮\n";
}
else if (result == ContentDialogResult.None)
{
lblMsg.Text += "没有选择按钮\n";
}
}
}
}

3、MapControl
MapControlDemo.xaml

<Page
x:Class="Demo.Control.MapControlDemo"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:Demo.Control"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
Background="{ThemeResource ApplicationPageBackgroundThemeBrush}" xmlns:Maps="using:Windows.UI.Xaml.Controls.Maps"> <Grid>
<StackPanel Orientation="Vertical"> <TextBlock TextWrapping="Wrap">
<Run>MapControl - 又一个地图控件(Windows.UI.Xaml.Controls.Maps.MapControl)</Run>
<LineBreak />
<Run>这个地图控件更灵活一些,其支持通过 tile 来显示地图,tile 的来源可以有三种,分别是:HttpMapTileDataSource, LocalMapTileDataSource, CustomMapTileDataSource</Run>
</TextBlock> </StackPanel>
</Grid>
</Page>

MapControlDemo.xaml.cs

/*
* MapControl - 又一个地图控件(Windows.UI.Xaml.Controls.Maps.MapControl)
*
* 这个地图控件更灵活一些,其支持通过 tile 来显示地图,tile 的来源可以有三种,分别是:HttpMapTileDataSource, LocalMapTileDataSource, CustomMapTileDataSource
*
*/ using Windows.UI.Xaml.Controls; namespace Demo.Control
{
public sealed partial class MapControlDemo : Page
{
public MapControlDemo()
{
this.InitializeComponent();
}
}
}
