- 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; namespace Windows10.Controls.ProgressControl { 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
Controls/ProgressControl/ProgressBarDemo.xaml
<Page x:Class="Windows10.Controls.ProgressControl.ProgressBarDemo" 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"> <!-- 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}" ShowError="{Binding IsChecked, ElementName=radError}" /> <ProgressBar IsIndeterminate="False" Width="200" Minimum="0" Maximum="100" Value="50" HorizontalAlignment="Left" Margin="0 20 0 0" Foreground="Orange" Background="Red" 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>
Controls/ProgressControl/ProgressBarDemo.xaml.cs
/* * ProgressBar - 进度条控件(继承自 RangeBase, 请参见 /Controls/ProgressControl/RangeBaseDemo.xaml) */ using Windows.UI.Xaml.Controls; namespace Windows10.Controls.ProgressControl { public sealed partial class ProgressBarDemo : Page { public ProgressBarDemo() { this.InitializeComponent(); } } }
4、ProgressRing 的示例
Controls/ProgressControl/ProgressRingDemo.xaml
<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" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 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}"/> <CheckBox Name="chkIsActive" Margin="5" Content="IsActive" IsChecked="True" /> </StackPanel> </Grid> </Page>
Controls/ProgressControl/ProgressRingDemo.xaml.cs
/* * ProgressRing - 进度圈控件(继承自 Control, 请参见 /Controls/BaseControl/ControlDemo/) */ using Windows.UI.Xaml.Controls; namespace Windows10.Controls.ProgressControl { public sealed partial class ProgressRingDemo : Page { public ProgressRingDemo() { this.InitializeComponent(); } } }
