1，页面切换和命令绑定

效果

实现思路

2，弹出抽屉侧滑窗的效果

【2.1】效果

【2.2】侧滑栏代码

            <!--抽屉侧滑栏，Background="#EE444444" 是1个半透明的效果-->
                <Border Background="#EE444444" Width="240" HorizontalAlignment="Right" CornerRadius="5">
                <!--添加阴影效果，这里不是很明显，Direction是阴影的方向，180是阴影在左边-->
                <Border.Effect>
                        <DropShadowEffect Color="Gray" ShadowDepth="0" BlurRadius="5" Opacity="0.3" Direction="180"></DropShadowEffect>
                    </Border.Effect>
                <!--位移变形实现抽屉侧滑，实际上是改变X的值-->
                    <Border.RenderTransform>
                        <TranslateTransform X="250" x:Name="tt"></TranslateTransform>
                    </Border.RenderTransform>
                    <Button Width="40" Height="40" VerticalAlignment="Top" HorizontalAlignment="Left" Name="btnCloseUserInfo"
                           BorderThickness="0" Content="" FontFamily="../Assets/Iconfont/#iconfont"></Button>
                </Border>

　　

【2.3】

                    <!--动画目标，把谁的什么属性在多少时间内从当前值变化到0，打开抽屉窗-->
                    <Storyboard x:Key="UserInfoStoryboard">
                        <DoubleAnimation Duration="0:0:0.2" To="0"
                                         Storyboard.TargetName="tt"
                                         Storyboard.TargetProperty="X">
                        </DoubleAnimation>
                    </Storyboard>
                    <!--动画目标，隐藏抽屉窗-->
                    <Storyboard x:Key="CloseUserInfoStoryboard">
                        <DoubleAnimation Duration="0:0:0.2"
                                         Storyboard.TargetName="tt"
                                         Storyboard.TargetProperty="X">
                        </DoubleAnimation>
                    </Storyboard>

　　

【2.4】

    <Window.Triggers>
        <!--点击btnUserInfo触发UserInfoStoryboard打开抽屉窗-->
        <EventTrigger RoutedEvent="Button.Click" SourceName="btnUserInfo">
            <BeginStoryboard Storyboard="{StaticResource UserInfoStoryboard}"></BeginStoryboard>
        </EventTrigger>
        <EventTrigger RoutedEvent="Button.Click" SourceName="btnCloseUserInfo">
            <BeginStoryboard Storyboard="{StaticResource CloseUserInfoStoryboard}"></BeginStoryboard>
        </EventTrigger>
    </Window.Triggers>
