在论坛上见到有人提出了这个问题（WPF实现点击横向切换界面）

我简单地做了个Sample。

设计思路

将这多个界面放入一个Orientation为Horizontal的StackPanel当中，点击Next时，里面所有控件执行TranslteTransform动画。

实现

xaml

WPF如何实现类似iPhone界面切换的效果 （version .2）

转自：http://blog.csdn.net/fallincloud/article/details/6969329

前面写了篇WPF如何实现类似iPhone界面切换的效果 （version .1）

现在又花了点时间重构了下，将动画的效果和Previous和Next这两个按钮的状态控制都封装了起来，效果依然和前面一样

不过重用性高了许多。使用方法如下:

XAML:

  1. <Windowx:Class="WPFNavigation.MainWindow"
  2. xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  3. xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  4. xmlns:local="clr-namespace:WPFNavigation"
  5. Title="MainWindow"Height="350"Width="400">
  6. <Grid>
  7. <Grid.RowDefinitions>
  8. <RowDefinitionHeight="*"></RowDefinition>
  9. <RowDefinitionHeight="Auto"></RowDefinition>
  10. </Grid.RowDefinitions>
  11. <local:NavigationPanelOrientation="Horizontal"
  12. x:Name="NavigationPanel"
  13. Height="300"
  14. HorizontalAlignment="Left"
  15. VerticalAlignment="Top">
  17. <GridWidth="{BindingRelativeSource={RelativeSourceMode=FindAncestor,AncestorLevel=1,AncestorType={x:TypeWindow}},Path=ActualWidth}"
  18. Height="{BindingRelativeSource={RelativeSourceMode=FindAncestor,AncestorLevel=1,AncestorType={x:Typelocal:NavigationPanel}},Path=ActualHeight}"
  19. Background="Blue">
  20. <TextBlockFontSize="36">Page1</TextBlock>
  21. </Grid>
  22. <GridWidth="{BindingRelativeSource={RelativeSourceMode=FindAncestor,AncestorLevel=1,AncestorType={x:TypeWindow}},Path=ActualWidth}"
  23. Height="{BindingRelativeSource={RelativeSourceMode=FindAncestor,AncestorLevel=1,AncestorType={x:Typelocal:NavigationPanel}},Path=ActualHeight}"
  24. Background="Violet">
  25. <TextBlockFontSize="36">Page2</TextBlock>
  26. </Grid>
  27. <GridWidth="{BindingRelativeSource={RelativeSourceMode=FindAncestor,AncestorLevel=1,AncestorType={x:TypeWindow}},Path=ActualWidth}"
  28. Height="{BindingRelativeSource={RelativeSourceMode=FindAncestor,AncestorLevel=1,AncestorType={x:Typelocal:NavigationPanel}},Path=ActualHeight}"
  29. Background="Purple">
  30. <TextBlockFontSize="36">Page3</TextBlock>
  31. </Grid>
  32. </local:NavigationPanel>
  34. <StackPanelGrid.Row="1"Orientation="Horizontal">
  35. <ButtonContent="Previous"x:Name="ButtonPreviousPage"
  36. IsEnabled="{BindingElementName=NavigationPanel,Path=PreviousIsValid,Mode=OneWay}"
  37. Click="ButtonPreviousPage_Click"></Button>
  38. <ButtonContent="Next"x:Name="ButtonNextPage"Click="ButtonNextPage_Click"
  39. IsEnabled="{BindingElementName=NavigationPanel,Path=NextIsValid,Mode=OneWay}"></Button>
  40. </StackPanel>
  41. </Grid>
  42. </Window>

C#:

  1. ///<summary>
  2. ///InteractionlogicforMainWindow.xaml
  3. ///</summary>
  4. publicpartialclassMainWindow:Window
  5. {
  6. publicMainWindow()
  7. {
  8. InitializeComponent();
  9. }
  11. privatevoidButtonPreviousPage_Click(objectsender,RoutedEventArgse)
  12. {
  13. NavigationPanel.Previous();
  14. }
  17. privatevoidButtonNextPage_Click(objectsender,RoutedEventArgse)
  18. {
  19. NavigationPanel.Next();
  20. }
  21. }

以上是用法，封装的NavigationPanel设计如下：
