win10 UWP 圆形等待

看到一个圆形好像微软ProgressRing

我们可以用自定义控件

按ctrl+shift+a

用户控件

我们可以用Rectangle做圆形边

只要Rectangle RadiusX>0圆角

因为每个Rectangle 都一样，我们可以资源

        <Grid.Resources>

        </Grid.Resources>

设置Rectangle 在中间

资源设置需要选TargetType

我们是Rectangle

                <Style x:Key="RectangleStyle1" TargetType="Rectangle">

                </Style>

因为不知道这个要叫什么，就用右击资源

vs默认RectangleStyle1

每个项需要

                    <Setter Property="" Value=""/>

设置中间

                <Style x:Key="RectangleStyle1" TargetType="Rectangle">

                    <Setter Property="HorizontalAlignment" Value="Center"/>

                    <Setter Property="VerticalAlignment" Value="Center"/>

                </Style>

看起来Rectangle很大

把Height为20

                    <Setter Property="Height" Value="50"/>

                    <Setter Property="Width" Value="2"/>

全部资源

 <Style x:Key="RectangleStyle1" TargetType="Rectangle">

                    <Setter Property="RadiusX" Value="1"/>

                    <Setter Property="RadiusY" Value="2"/>

                    <Setter Property="Fill" Value="Black"/>

                    <Setter Property="Opacity" Value="0.2"/>

                    <Setter Property="RenderTransformOrigin" Value="0.5,0.5"/>

                    <Setter Property="HorizontalAlignment" Value="Center"/>

                    <Setter Property="VerticalAlignment" Value="Top"/>

                    <Setter Property="Height" Value="50"/>

                    <Setter Property="Width" Value="2"/>

                </Style>

我们做10个Rectangle

使用RectangleStyle1 在Rectangle style="{StaticResource RectangleStyle1}"

中间是白色比较好

            <Ellipse Height="10" Width="10" Fill="White" HorizontalAlignment="Center" VerticalAlignment="Center"/>

每个Rectangle 一个名字

我们想要xaml动，可以

            <Grid.Triggers>

                <EventTrigger RoutedEvent="Grid.Loaded">

                    <BeginStoryboard>
