    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"

        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: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
