Hyperlink
WPF中超链接类型是Hyperlink，除了能在页面之间导航，还能再同一个页面下进行段落导航
实例：
<Grid>
<FlowDocumentReader>
<FlowDocument>
<Section LineHeight="" FontSize="">
<List>
<ListItem>
<Paragraph>
<Hyperlink NavigateUri="CustomPage.xaml#first">
First Paragraph
</Hyperlink>
</Paragraph>
</ListItem>
<ListItem>
<Paragraph>
<Hyperlink NavigateUri="CustomPage.xaml#second">
Second Paragraph
</Hyperlink>
</Paragraph>
</ListItem>
</List>
</Section>
<Paragraph x:Name="first" FontSize="" Background="AliceBlue">
. First paragraph content
</Paragraph>
<Paragraph x:Name="second" FontSize="" Background="AliceBlue">
. Second paragraph content
</Paragraph>
<Paragraph>
<Hyperlink NavigateUri="SimplePage.xaml" >
Hello WPF
</Hyperlink>
</Paragraph>
</FlowDocument>
</FlowDocumentReader>
</Grid>
如果页面寄宿窗口不是NavigationWindow，超链接是无法导航的
通过编写代码导航
在某些情况下Hyperlink不能实现，需要通过NavigationService来实现
1.导航需要传值
2.导航到页面之前要设置属性
3.运行时才知道要导航到哪个页面
实例：
DemoPage.xaml
<Page.Resources>
<Style TargetType="TextBlock">
<Setter Property="FontSize" Value="" />
<Setter Property="Margin" Value="" />
</Style>
</Page.Resources>
<StackPanel>
<TextBlock>
Navigate to
<Hyperlink x:Name="link1" Click="link_click">
SimplePage.xaml
</Hyperlink>
</TextBlock>
<TextBlock>
Navigate to
<Hyperlink x:Name="link2" Click="link_click">
SimplePage.xaml
</Hyperlink>
(Call a constructor with parameter)
</TextBlock>
<TextBlock>
Navigate to
<Hyperlink x:Name="link3" Click="link_click">
.Net Object
</Hyperlink>
</TextBlock>
<TextBlock>
Navigate to site
<Hyperlink x:Name="link4" Click="link_click">
http://www.bing.com
</Hyperlink>
</TextBlock>
</StackPanel>
class Person
{
public string Name { get; set; }
public int Age { get; set; } public override string ToString()
{
return "Name: " + Name + "\nAge: " + Age;
}
}
Page.xaml.cs
private void link_click(object sender, RoutedEventArgs e)
{
Hyperlink link = sender as Hyperlink;
if (link == link1)
{
NavigationService.Navigate(new Uri("pack://application:,,,/SimplePage.xaml"));
}
else if (link == link2)
{
NavigationService.Navigate(new SimplePage("Hello Navigation"));
}else if (link == link3)
{
NavigationService.Navigate(new Person() { Name = "Alex", Age = });
}
else if (link == link4)
{
NavigationService.Navigate(new Uri("http://www.bing.com"));
}
}
其他导航方式
导航工具栏
导航命令
添加Button控制导航，相当于自定义导航工具栏
<Button Height="" Width="" Content="Back" Command="NavigationCommands.BrowseBack" />
<Button Height="" Width="" Content="Forward" Command="NavigationCommands.BrowseForward" />
历史记录
WPF中Jaurnal记录了每一次导航操作，从而实现导航工具栏的功能
Journal 包含两个数据栈用来记录前进和后退页面的显示状态，每个相关 Page 都会对应一个 JournalEntry。日志状态自动恢复仅对单击导航条上前进后退按钮有效。
