手把手教你:亲手打造Silverlight的Win8 Metro外观(3) 子菜单项

用过win8 的同鞋都会发现. 当你按下win 键后, 打开菜单的时候..所有的菜单都会有一个小动画,关闭亦是如此.

所以我们要给desktopitem 添加二个状态 Open & Close

由于我们所做的都是模版化控件,因此无法在blend 中直接编辑且可视化的编辑.所做动画我们必须自己建一个临时项目或用户控件..做好后COPY代码即可.

打开Blend, 新建一个项目..托入一个border

点击状态.

添加一个状态组 VisualStateGroup

然后在VisualStateGroup 下添加2个状态

Show

Hide

然后我们选择Show先给Show做上动画..

然后打开时间线(什么? 你找不到时间线在哪打开?)

在时间线分别添加 3个时间点 , 0(0秒) 0.4(0.4秒=400ms) 0.5

在0时间上将缩放改为 0.5 透明度0

0.4时间上缩放改为1.2 透明度1

0.5时间缩放改为1

些时会有一个变大并伴有反弹效果

接着切换到Hide状态上同上添加2个时间点 0 0.5

0.5缩放为0.5 透明度0

此时动画制作完毕, 将代码COPY到项目模版的外观代码中

在DesktopItem的模版Template中放入一个按钮

使其Tag值绑定数据的Code值 (Code存放的是xaml页面名)

<Button x:Name="desktopItemButton" Style="{StaticResource TileIcon_Btn}" Tag="{Binding Code}" >
                            <TextBlock Text="{Binding Name}" HorizontalAlignment="Right" VerticalAlignment="Bottom" />
</Button>

完整的模版样式代码

 2         <Setter Property="Background" Value="LightCoral" />
 3         <Setter Property="Template">

 5                 <ControlTemplate TargetType="local:DesktopItem">

58             </Setter.Value>
59         </Setter>
60     </Style>

转到DesktopItem 的cs 代码窗口, 重写OnApplyTemplate事件.

加入状态转换

1         public override void OnApplyTemplate()
2         {
3             base.OnApplyTemplate();
4             VisualStateManager.GoToState(this, "Show", false);
5         }

到此菜单全部制作完毕, 测试效果.!

测试数据为:

desktopView.ItemsSource = 
            new List<TestModel> 
            {
                new TestModel {
                    Name = "编码设置",
                    Children = new List<TestModel> { 
                        new TestModel { Name = "00101",  Code = "Test" } ,
                        new TestModel { Name = "00102", Code="Test1" } ,
                        new TestModel { Name = "00103",  } 
                    } 
                },
                new TestModel {
                    Name = "系统设置",
                    Children = new List<TestModel> { 
                        new TestModel { Name = "00201" } 
                    }
                },
            };

<local:Desktop x:Name="desktopView" />
