NavigateToPageAction打开新页面

首先要加上两个命名空间

分别为:

1. xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
2. xmlns:ec="clr-namespace:Microsoft.Expression.Interactivity.Core;assembly=Microsoft.Expression.Interactions"

  xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
  xmlns:ec="clr-namespace:Microsoft.Expression.Interactivity.Core;assembly=Microsoft.Expression.Interactions"

然后

1. <Button Content="Button" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="170,239,0,0" Grid.Row="1">
2. <i:Interaction.Triggers>
3. <i:EventTrigger EventName="Click">
4. <ec:NavigateToPageAction TargetPage="/Page1.xaml"/>
5. </i:EventTrigger>
6. </i:Interaction.Triggers>

<Button Content="Button" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="170,239,0,0" Grid.Row="1">
            <i:Interaction.Triggers>
                <i:EventTrigger EventName="Click">
                    <ec:NavigateToPageAction TargetPage="/Page1.xaml"/>
                </i:EventTrigger>
            </i:Interaction.Triggers>

</Button>

使用NavigateToPageAction还可以传递查询字符串:

我们可以用NavigationContext.QueryString,把查询字符串读出来

1. //NavigateToPageAction is also very useful for Binding data to NavigationContext.QueryString
2. <ListBox>
3. ...
4. <i:Interaction.Triggers>
5. <i:EventTrigger EventName="SelectionChanged">
6. <ec:NavigateToPageAction>
7. <ec:NavigateToPageAction.TargetPage>
8. <Binding Path="SelectedIndex" ElementName="MainListBox"
9. StringFormat="/DetailsPage.xaml?selectedItem={0}"/>
10. </ec:NavigateToPageAction.TargetPage>
11. </ec:NavigateToPageAction>
12. </i:EventTrigger>
13. </i:Interaction.Triggers>
14. </ListBox>
