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

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"

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

        <!--

        -->
        <StackPanel Margin="120 0 0 0">
            <Slider Width="100" SmallChange="2" Value="20" HorizontalAlignment="Left" />

            <Slider Height="100" Orientation="Vertical" IsDirectionReversed="True" HorizontalAlignment="Left"

            <!--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;
        }
    }
}
