介绍
背水一战 Windows 10 之 控件(进度类)

  • RangeBase
  • Slider
  • ProgressBar
  • ProgressRing



示例
1、RangeBase(基类) 的示例
Controls/ProgressControl/RangeBaseDemo.xaml

<Page
    x:Class="Windows10.Controls.ProgressControl.RangeBaseDemo"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Windows10.Controls.ProgressControl"
    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="10 0 10 10">

            <TextBlock Name="lblMsg" Margin="5" />
            
            <!--
                Slider - 滑动条控件,继承自 RangeBase,下面介绍 RangeBase 的相关知识点
                    Minimum - 范围控件的最小值(double 类型)
                    Maximum - 范围控件的最大值(double 类型)
                    Value - 范围控件的当前值(double 类型)
                    SmallChange - 小变化步长(double 类型),按键盘的“上/下/左/右”键
                    LargeChange - 大变化步长(double 类型),按键盘的“PageUp/PageDown”键(经测试无效,另外 Home 键和 End 键是可用的)
                    ValueChanged - 范围控件的当前值发生变化后触发的事件
            -->

            <Slider Name="slider" Width="200" Margin="5" HorizontalAlignment="Left" Foreground="Orange" Background="Red" Style="{StaticResource MySliderStyle}"
                    Minimum="1000" Maximum="2000" Value="1500" SmallChange="10" LargeChange="100" ValueChanged="slider_ValueChanged">
            </Slider>

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

Controls/ProgressControl/RangeBaseDemo.xaml.cs

/*
 * RangeBase(基类) - 范围控件基类(继承自 Control, 请参见 /Controls/BaseControl/ControlDemo/)
 */

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

namespace Windows10.Controls.ProgressControl
{
    public sealed partial class RangeBaseDemo : Page
    {
        public RangeBaseDemo()
        {
            this.InitializeComponent();
        }

        private void slider_ValueChanged(object sender, RangeBaseValueChangedEventArgs e)
        {
            // RangeBaseValueChangedEventArgs
            //     OldValue - 范围控件的之前的值
            //     NewValue - 范围控件的当前的值
            lblMsg.Text = $"slider old value:{e.OldValue}, slider new value:{e.NewValue}";
        }
    }
}


2、Slider 的示例
Controls/ProgressControl/SliderDemo.xaml

<Page
    x:Class="Windows10.Controls.ProgressControl.SliderDemo"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Windows10.Controls.ProgressControl"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Grid Background="Transparent">

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

        <!--
            Slider - 滑动条控件
                Header - 可以设置一个纯文本,不能命中测试,空 Header 的话不会占用任何空间
                HeaderTemplate - 可以将 Header 设置为任何 xaml,且支持命中测试
                Orientation - 滑动条的布局方向
                    Horizontal - 水平放置
                    Vertical - 垂直放置
                IsDirectionReversed - 值的增加方向为左到右或下到上则为 false(默认值),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
                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 - 贴靠方式
                    StepValues - 按 StepFrequency 做 Snap(默认值)
                        通过鼠标拖动或鼠标点击控制 Slider 时,其值是 StepFrequency 的整倍数(注:键盘控制时,步长来自于基类 RangeBase 的 SmallChange, LargeChange)
                    Ticks - 按 TickFrequency 做 Snap
                        通过鼠标拖动或鼠标点击控制 Slider 时,其值是 TickFrequency 的整倍数(注:键盘控制时,步长来自于基类 RangeBase 的 SmallChange, LargeChange)
        
            注:可以通过 Foreground, Background 来设置 Slider 的部分状态的颜色,更多的样式设置还是要去修改控件模板
        -->
        <StackPanel Margin="10 0 10 10">

            <Slider Margin="5" Width="100" Value="20" HorizontalAlignment="Left" Foreground="Orange" Background="Red" Style="{StaticResource MySliderStyle}"
                    Header="Slider" />

            <Slider Margin="5" Height="100" HorizontalAlignment="Left" Foreground="Orange" Background="Red" Style="{StaticResource MySliderStyle}"
                    Orientation="Vertical" IsDirectionReversed="True" 
                    IsThumbToolTipEnabled="True" ThumbToolTipValueConverter="{StaticResource MyThumbToolTipValueConverter}">
                <Slider.HeaderTemplate>
                    <DataTemplate>
                        <TextBlock Text="Slider" Foreground="Red" />
                    </DataTemplate>
                </Slider.HeaderTemplate>
            </Slider>

            <Slider Margin="5" Width="800" Minimum="0" Maximum="800" HorizontalAlignment="Left"  Foreground="Orange" Background="Red" Style="{StaticResource MySliderStyle}"
                    TickPlacement="Inline" TickFrequency="80" 
                    StepFrequency="100" SnapsTo="StepValues" />

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

Controls/ProgressControl/SliderDemo.xaml.cs

/*
 * Slider - 滑动条控件(继承自 RangeBase, 请参见 /Controls/ProgressControl/RangeBaseDemo.xaml)
 * 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;

{
    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 thumb 旁显示的当前值的后面加一个百分号
            return value + "%";
        }

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


3、ProgressBar 的示例

    mc:Ignorable="d">

    <Grid Background="Transparent">
        <StackPanel Margin="10 0 10 10">

            <!--
                ProgressBar - 进度条控件
                    IsIndeterminate - 是否是无法确定进度的进度条
                    ShowPaused - 显示暂停状态
                    ShowError - 显示错误状态
            
                注:可以通过 Foreground, Background 来设置 ProgressBar 的部分状态的颜色,更多的样式设置还是要去修改控件模板
            -->

            <ProgressBar IsIndeterminate="True" Width="200" HorizontalAlignment="Left" 
                         Foreground="Orange" Background="Red"
                         ShowPaused="{Binding IsChecked, ElementName=radPaused}"

<Page
    x:Class="Windows10.Controls.ProgressControl.ProgressRingDemo"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Windows10.Controls.ProgressControl"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

    mc:Ignorable="d">

    <Grid Background="Transparent">
        <StackPanel Margin="10 0 10 10">

            <!--
                ProgressRing - 进度圈控件
                    IsActive - 是否显示
            -->
            <ProgressRing Margin="5" Foreground="White" Width="200" Height="200" HorizontalAlignment="Left" 
                          IsActive="{Binding IsChecked, ElementName=chkIsActive}"/>

{
    public sealed partial class ProgressRingDemo : Page
    {
