如何默认导航屏幕？ [英] How to naviagate screens by default?

问题描述

大家好，我们需要自动显示演示，需要让一个屏幕完成，下一个屏幕开始加载（以秒为间隔）。如何实现？

BTW，每个屏幕都可能包含动画。

当故事板完成但是不起作用时我使用以下内容：

 

void m_StoryboardSwitch_Completed（ object 发件人， EventArgs e）

{

 

NavigateToScreenAction navigateAction = 新 NavigateToScreenAction （）;

navigateAction.TargetScreen =

" AnimationScreens.Screen_1_2" ;

}

但是，没有办法勾选SketchFlow动画的结束事件，所以我有使用StoryBoard。欢迎任何提示。

提前感谢您的建议，

解决方案

使用行为进行操作（可能更容易）：
右键单击对象和时间轴面板中的layoutroot，然后选择 - >导航到 - >您想要的画面
在对象和时间轴面板中选择新添加的行为
在属性面板中，找到触发器部分并单击新建
选择StoryboardCompletedTrigger
将故事板设置为你想要使用的人

用代码来做：第一轮Screen_1（）
{
this.InitializeComponent（）;
var sb = this.Resources [" Storyboard1"] as System.Windows.Media.Animation.Storyboard;
sb.Completed + = new EventHandler（sb_Completed）;
}

void sb_Completed（object sender，EventArgs e）
{
Microsoft.Expression.Prototyping.Services.PlayerContext.Instance.ActiveNavigationViewModel.NavigateToScreen（" WpfPrototype5Screens .Screen_2"，true）;
}

Hi All,

We need show the demo automatically, which need let one screen finishes, the next screen begin loading(with several seconds as interval). How to implement that?

BTW, each screen may contains animation.

I use the following when a storyboard finished, but doesn't work:

 

void m_StoryboardSwitch_Completed(object sender, EventArgs e)

{

 

NavigateToScreenAction navigateAction = new NavigateToScreenAction();

navigateAction.TargetScreen =

"AnimationScreens.Screen_1_2";

}

However, there is no way to hook the finish event of SketchFlow Animation, so I have to use StoryBoard. Any hint are welcome.


Thanks for your advice in advance,

Yuanzi

解决方案

To do it with behaviors (probably easier):
Right click layoutroot in the objects and timeline panel, and select -> navigate to -> the screen you want
Select the newly added behavior in the objects and timeline panel
In the properties panel, find the trigger section and click new
Select a StoryboardCompletedTrigger
Set the storyboard to the one you want to use

To do it with code:

	public Screen_1()
		{
			this.InitializeComponent();
			var sb = this.Resources["Storyboard1"] as System.Windows.Media.Animation.Storyboard;
            sb.Completed += new EventHandler(sb_Completed);
		}

        void sb_Completed(object sender, EventArgs e)
        {
            Microsoft.Expression.Prototyping.Services.PlayerContext.Instance.ActiveNavigationViewModel.NavigateToScreen("WpfPrototype5Screens.Screen_2", true);
        }
