C# WPF Frame how to create slide effect on pages?
提问by Oh My Dog
I want to make a page slide effect on WPF, Frame control. here we go.
我想在WPF，Frame控件上制作页面幻灯片效果。开始了。
First of all, I put a frame and 2 buttons for navigation:
首先，我放了一个框架和两个导航按钮：
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="25"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="25"/>
</Grid.ColumnDefinitions>
<Frame x:Name="frame" Source="page1.xaml" Grid.Column="1" />
<Button Grid.Column="0" Content="<" Click="GoPrevious"/>
<Button Grid.Column="2" Content=">" Click="GoNext"/>
</Grid>
Then I create 3 Pages in difference colors: Page1.xaml, Page2.xaml and Page3.xaml
然后我创建了 3 个不同颜色的页面：Page1.xaml、Page2.xaml 和 Page3.xaml
now when click navigation button, will just simply navigate to an uri:
现在，当单击导航按钮时，只需导航到一个 uri：
frame.Navigate(new Uri("page2.xaml", UriKind.Relative));
Done. Now I want to make each page slide when navigated (everybody want it). So my plan is to set every page's Loaded EventTrigger:
完毕。现在我想在导航时使每个页面滑动（每个人都想要它）。所以我的计划是设置每个页面的 Loaded EventTrigger：
<Page.Triggers>
<EventTrigger RoutedEvent="FrameworkElement.Loaded">
<BeginStoryboard>
<Storyboard>
<ThicknessAnimation Duration="0:0:0.75" Storyboard.TargetProperty="Margin" From="500,0,-500,0" To="0" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
<EventTrigger RoutedEvent="FrameworkElement.Unloaded">
<BeginStoryboard>
<Storyboard>
<ThicknessAnimation Duration="0:0:0.75" Storyboard.TargetProperty="Margin" From="0" To="-500,0,500,0" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Page.Triggers>
And it works! Everything goes fine until i found the pages are not continuous, means, when you navigate to page2, page1 will unload immediately, than begin page2 loaded event. I tried to set page1's unload event, but not work.
它有效！一切正常，直到我发现页面不连续，这意味着，当您导航到 page2 时，page1 将立即卸载，而不是开始 page2 加载事件。我试图设置 page1 的卸载事件，但不起作用。
what I want is, when page1 begin to exit, page2 should be coming to stage right away, like a train one by one.
我想要的是，当page1开始退出时，page2应该马上就上台了，就像一列火车一样。
So how to do it? Thanks.
那么怎么做呢？谢谢。

I have done it using a separate Frameper Page. As if we try to show a new webpage in a website, it's not possible without using some trick. Same is the case here. And for sliding effect, StackPanelwith Orientation=Horizontallooks ok.
我已经使用单独的Frameper完成了它Page。就像我们尝试在网站中显示一个新网页一样，不使用一些技巧是不可能的。这里的情况也是如此。而对于滑动效果，StackPanel与Orientation=Horizontal看起来不错。
Note : In Frame style, I have used main Grid(Grd) to set width, as when we add children(a new Frame) to StackPanel it's Width will increase.
注意：在框架样式中，我使用主网格（Grd）来设置宽度，因为当我们将子项（一个新框架）添加到 StackPanel 时，它的宽度会增加。
You can build upon this concept.
你可以建立在这个概念之上。
<Grid Background="#FF33CF2C" x:Name="Grd">
<StackPanel x:Name="StkPnl" Orientation="Horizontal">
<StackPanel.Resources>
<Style TargetType="Frame">
<Setter Property="Margin" Value="0,50,0,0"/>
<Setter Property="Width" Value="{Binding ActualWidth, ElementName=Grd}"/>
<Setter Property="NavigationUIVisibility" Value="Hidden"/>
</Style>
</StackPanel.Resources>
<Frame x:Name="FramePage1" Source="/WpfNavigation;component/Sliding/Page1.xaml" />
</StackPanel>
<Button Content="Goto Page2" HorizontalAlignment="Left" Margin="114,18,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click">
<Button.Triggers>
<EventTrigger RoutedEvent="ButtonBase.Click">
<BeginStoryboard>
<Storyboard Storyboard.TargetName="FramePage1" Storyboard.TargetProperty="Margin">
<ThicknessAnimation To="-2000 , 50 , 0, 0" Duration="0:0:5"/>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Button.Triggers>
</Button>
</Grid>

private void Button_Click(object sender, RoutedEventArgs e)
{
Frame f = new Frame();
f.Source = new Uri("pack://application:,,,/Sliding/Page2.xaml", UriKind.Absolute);
StkPnl.Children.Add(f);
}
