介绍
重新想象 Windows 8 Store Apps 之提示控件

ProgressRing - 进度圈控件

重新想象 Windows 8 Store Apps 之范围控件

ProgressBar - 进度条控件

Slider - 滑动条控件

示例
1、ProgressRing 的 Demo
ProgressRingDemo.xaml

<Page
x:Class="XamlDemo.Controls.ProgressRingDemo"
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">

<Grid Background="Transparent">
<StackPanel Margin="120 0 0 0">

<!--
ProgressRing - 进度圈控件
IsActive - 是否显示
-->
<ProgressRing IsActive="{Binding IsChecked, ElementName=chkRunning}" Width="200" Height="200" HorizontalAlignment="Left" />

<CheckBox Name="chkRunning" Content="Running" IsChecked="True" />
</StackPanel>
</Grid>
</Page>

2、ProgressBar 的 Demo
ProgressBarDemo.xaml

<Page
x:Class="XamlDemo.Controls.ProgressBarDemo"
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">

<Grid Background="Transparent">
<StackPanel Margin="120 0 0 0">

<!--
ProgressBar - 进度条控件
IsIndeterminate - 是否是无法确定进度的进度条
Minimum - 进度条的最小值
Maximum - 进度条的最大值
Value - 进度条的当前值
ShowPaused - 显示暂停状态
ShowError - 显示错误状态
ValueChanged - 进度条的当前值发生变化后所触发的事件
-->

<ProgressBar IsIndeterminate="True" Width="200" HorizontalAlignment="Left"
ShowPaused="{Binding IsChecked, ElementName=radPaused}"
ShowError="{Binding IsChecked, ElementName=radError}" />

<ProgressBar IsIndeterminate="False" Width="200" Minimum="0" Maximum="100" Value="50"  HorizontalAlignment="Left" Margin="0 20 0 0"
ShowPaused="{Binding IsChecked, ElementName=radPaused}"
ShowError="{Binding IsChecked, ElementName=radError}"/>

<StackPanel Orientation="Horizontal" Margin="0 20 0 0">
<RadioButton x:Name="radRunning" GroupName="ProgressState" Content="Running" IsChecked="True"/>
<RadioButton x:Name="radPaused" GroupName="ProgressState" Content="Paused"/>
<RadioButton x:Name="radError" GroupName="ProgressState" Content="Error"/>
</StackPanel>

</StackPanel>
</Grid>
</Page>

3、Slider 的 Demo
SliderDemo.xaml

<Page
x:Class="XamlDemo.Controls.SliderDemo"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:XamlDemo.Controls"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:myControls="using:MyControls"
mc:Ignorable="d">

<Grid Background="Transparent">

<Grid.Resources>
<local:MyThumbToolTipValueConverter x:Key="MyThumbToolTipValueConverter" />
</Grid.Resources>

<!--
Slider - 滑动条控件
Value - 滑动条的值
SmallChange - 按键盘左右键时，滑动条的值的变化量
Orientation - 滑动条的布局方向，Horizontal:水平放置，Vertical:垂直放置
IsDirectionReversed - 增加值方向为左到右或下到上则为 false，反之为 true
IsThumbToolTipEnabled - 是否在 thumb 旁显示当前值的提示
ThumbToolTipValueConverter - 在 thumb 旁显示当前值的提示时所使用的 Converter
Minimum - 最小值
Maximum - 最大值
ValueChanged - 当前值发生变化后所触发的事件
TickPlacement - 如何显示刻度线，Windows.UI.Xaml.Controls.Primitives.TickPlacement枚举（None, TopLeft, BottomRight, Outside, Inline）
TickFrequency - 刻度线的间隔
StepFrequency - 每一步的间隔
SnapsTo - 按 TickFrequency 做 Snap 还是按 StepFrequency 做 Snap，Windows.UI.Xaml.Controls.Primitives.SliderSnapsTo枚举
StepValues - 按 StepFrequency 做 Snap（默认值）
Ticks - 按 TickFrequency 做 Snap
-->
<StackPanel Margin="120 0 0 0">
<Slider Width="100" SmallChange="2" Value="20" HorizontalAlignment="Left" />

<Slider Height="100" Orientation="Vertical" IsDirectionReversed="True" HorizontalAlignment="Left"
IsThumbToolTipEnabled="True" ThumbToolTipValueConverter="{StaticResource MyThumbToolTipValueConverter}" />

<Slider Width="800" Minimum="0" Maximum="800" StepFrequency="100" HorizontalAlignment="Left"
TickPlacement="Inline" TickFrequency="80" SnapsTo="StepValues" />

<!--自定义 Slider 使其具有圆角效果，类似 ios 的滑动条（具体实现参考 MyControls 项目中的 MySlider）-->
<myControls:MySlider Width="100" HorizontalAlignment="Left" />
</StackPanel>
</Grid>
</Page>

SliderDemo.xaml.cs

/*
* Slider - 滑动条控件
* Thumb - 可由用户拖动的控件（Slider 内的可拖动部分就是一个 Thumb 控件）
*/

using System;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Data;

namespace XamlDemo.Controls
{
public sealed partial class SliderDemo : Page
{
public SliderDemo()
{
this.InitializeComponent();
}
}

// 为 Slider 的 ThumbToolTipValueConverter 提供 Converter
public sealed class MyThumbToolTipValueConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, string language)
{
// 在 Slider 的值后面加一个百分号
return value + "%";
}

public object ConvertBack(object value, Type targetType, object parameter, string language)
{
return null;
}
}
}

4、自定义 Slider 使其具有圆角效果
MyControls/MySlider.cs

/*
* 改变 Slider 的样式，使其具有圆角效果，类似 ios 的滑动条
*/

using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Controls.Primitives;
using Windows.UI.Xaml.Shapes;

namespace MyControls
{
public class MySlider : Slider
{
// 原 loaded 背景（Slider 中已加载部分的背景）
private Rectangle _loadedBackground;
// 由于用原 loaded 背景实现圆角有一些问题，所以新增了一个 Rectangle 来辅助
private Rectangle _loadedBackgroundCustom;
private Thumb _thumb;

public MySlider() : base()
{
this.DefaultStyleKey = typeof(MySlider);
}

protected override void OnValueChanged(double oldValue, double newValue)
{
base.OnValueChanged(oldValue, newValue);

_loadedBackgroundCustom.HorizontalAlignment = Windows.UI.Xaml.HorizontalAlignment.Left;

// loaded 背景的宽度为原 loaded 背景的宽度加上 thumb 宽度的二分之一
_loadedBackgroundCustom.Width = _loadedBackground.Width + _thumb.Width / 2;
}

protected override void OnApplyTemplate()
{
base.OnApplyTemplate();

_loadedBackground = GetTemplateChild("HorizontalDecreaseRect") as Rectangle;
_loadedBackgroundCustom = GetTemplateChild("HorizontalBorderCustom") as Rectangle;
_thumb = GetTemplateChild("HorizontalThumb") as Thumb;
}
}
}
