win10 UWP button

button有很多和wpf一样，可以看《深入浅出WPF》

我们可以在button的click写上

<Button Content="确定" Click="Button_Click"/>

在Button_Click按F12到代码写上点击按钮需要运行

        private void Button_Click(object sender, RoutedEventArgs e)
        {

        }

也可以用viewModel的一个方法 viewModel有一个方法 ce

可以在Click写

Click="{x:Bind view.ce}"

在用view需要在MainPage.xaml.cs写

viewModel view {set;get;}= new viewModel();

button content可以使用一个元素，这个元素可以是Grid，我们可以做一个圆形头像

先找出一张图，我们把这张图做头像

把图放到项目

                <Button Height="100" Width="100" Margin="10,10,10,10" Padding="0" Foreground="{x:Null}" BorderBrush="{x:Null}" Background="{x:Null}"> 
                    <Button.Content>                       
                            <Ellipse Margin="0,0,0,0" Height="90" Width="90">
                                <Ellipse.Fill>
                                    <ImageBrush ImageSource="Assets/20151226160608688.jpg" />
                                </Ellipse.Fill>
                            </Ellipse>                                          
                    </Button.Content>
                </Button>

我们可以修改鼠标在按钮上的样子

button可以设置属性，使用资源 资源可以写在页面

    <Page.Resources>

    </Page.Resources>

所有按钮使用同样式

    <Page.Resources>
        <Style TargetType="Button">

        </Style>
    </Page.Resources>

按钮的属性用<Setter Property="属性" Value="值"/>

按钮的背景

    <Page.Resources>
        <Style TargetType="Button">
            <Setter Property="Background" Value="White"/>
        </Style>
    </Page.Resources>

指定一个样式，key

    <Page.Resources>
        <Style TargetType="Button">
            <Setter Property="Background" Value="White"/>
            <Setter Property="Width" Value="100"/>
            <Setter Property="Height" Value="100"/>
        </Style>
        <Style  x:Key="button" TargetType="Button">
            <Setter Property="Background" Value="White"/>
            <Setter Property="Width" Value="50"/>
            <Setter Property="Height" Value="50"/>
        </Style>
    </Page.Resources>

         <Button Content="默认"/>
         <Button Style="{StaticResource button}" Content="确定"/>

在设计，点按钮，右击，编辑模板副本，选择当前页

可以看到

    <Page.Resources>
        <Style x:Key="ButtonStyle1" TargetType="Button">
            <Setter Property="Background" Value="{ThemeResource SystemControlBackgroundBaseLowBrush}"/>
            <Setter Property="Foreground" Value="{ThemeResource SystemControlForegroundBaseHighBrush}"/>
            <Setter Property="BorderBrush" Value="{ThemeResource SystemControlForegroundTransparentBrush}"/>
            <Setter Property="BorderThickness" Value="{ThemeResource ButtonBorderThemeThickness}"/>
            <Setter Property="Padding" Value="8,4,8,4"/>
            <Setter Property="HorizontalAlignment" Value="Left"/>
            <Setter Property="VerticalAlignment" Value="Center"/>
            <Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}"/>
            <Setter Property="FontWeight" Value="Normal"/>
            <Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}"/>
            <Setter Property="UseSystemFocusVisuals" Value="True"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="Button">
                        <Grid x:Name="RootGrid" Background="{TemplateBinding Background}">
                            <VisualStateManager.VisualStateGroups>

在<VisualState x:Name="Pressed">可以把里面写成这个状态的样子，按钮有正常，按下，鼠标在按钮上，可以对每个修改

点击Pressed更改pressed看到这里按钮有背景去掉背景，按F4把背景无画笔添加过度记录关键帧选时间0.5改变背景选时间，改变背景点播放可以看到我们做出来的

可以运行
