複製silverlight中的超鏈接內容

如何使用mouse.simialr將silverlight中的超鏈接內容複製到我們如何在文本框中複製。複製silverlight中的超鏈接內容

我想知道如何選擇silverlight中的超鏈接內容，我目前使用HyperlinkTextStyle，它出現一個矩形，但是當我嘗試用鼠標選擇超鏈接中的內容時，我不能。

我使用以下樣式：

<Setter.Value> 
    <ControlTemplate TargetType="HyperlinkButton"> 
     <Grid 
      Cursor="{TemplateBinding Cursor}" 
      Background="{TemplateBinding Background}"> 
      <vsm:VisualStateManager.VisualStateGroups> 
       <vsm:VisualStateGroup x:Name="CommonStates"> 
       <vsm:VisualState x:Name="Normal"/> 
       <vsm:VisualState x:Name="MouseOver"> 
        <Storyboard> 
        <ObjectAnimationUsingKeyFrames 
         Duration="0" 
         Storyboard.TargetName="UnderlineTextBlock" 
         Storyboard.TargetProperty="Visibility"> 
         <DiscreteObjectKeyFrame KeyTime="0" Value="Visible"/> 
        </ObjectAnimationUsingKeyFrames> 
        </Storyboard> 
       </vsm:VisualState> 
       <vsm:VisualState x:Name="Pressed"> 
        <Storyboard> 
        <DoubleAnimation Duration="0" To="0.5" 
         Storyboard.TargetProperty="Opacity" 
         Storyboard.TargetName="TextElement"/> 
        </Storyboard> 
       </vsm:VisualState> 
       <vsm:VisualState x:Name="Disabled"> 
        <Storyboard> 
        <ObjectAnimationUsingKeyFrames Duration="0" 
         Storyboard.TargetName="DisabledOverlay" 
         Storyboard.TargetProperty="Visibility"> 
         <DiscreteObjectKeyFrame 
         KeyTime="0" Value="Visible"/>

最簡單的方式來獲得與可選擇的文本超鏈接將使用RichTextBox。試試這個，例如：

<RichTextBlock> 
    <Paragraph> 
     <Span></Span> 
     <Hyperlink NavigateUri="http://www.stackoverflow.com">Selectable</Hyperlink> 
     <Span></Span> 
    </Paragraph> 
</RichTextBlock>

上述可能不正是你想要的（你必須先點擊到左邊或文本選擇權 - 不能在中間點擊）。

另一種方法是使用一個TextBox，風格它看起來像一個超鏈接，並添加一個鼠標點擊事件進行導航。大致爲：

<TextBox x:Name="textBox" 
     Tag="http://www.stackoverflow.com" 
     Cursor="Hand" BorderThickness="0" Foreground="Blue" 
     Text="Selectable"/>

但是，這是一個有點棘手，因爲你需要弄清楚用戶是否點擊選擇，或點擊瀏覽。也許最好的辦法是同時處理「鼠標向下」和「鼠標向上」事件，如果它們之間的時間間隔爲< x毫秒，則執行導航。

此外，要使鼠標單擊事件正常工作，您必須使用AddHandler來添加偵聽器，因爲TextBox本身在控件內部處理鼠標點擊。所以，這樣的事情：

private DateTime? _downClickTime; 

public MyPage() 
{ 
    InitializeComponent(); 

    txt.AddHandler(MouseLeftButtonUpEvent, new MouseButtonEventHandler(TextBox_MouseLeftButtonUp), true); 
    txt.AddHandler(MouseLeftButtonDownEvent, new MouseButtonEventHandler(TextBox_MouseLeftButtonDown), true); 
} 

private void TextBox_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) 
{ 
    _downClickTime = DateTime.Now; 
} 

private void TextBox_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) 
{ 
    if (_downClickTime.HasValue && DateTime.Now.Subtract(_downClickTime.Value).TotalMilliseconds < 200) 
    { 
     var textBox = (TextBox)sender; 
     string url = textBox.Tag as string; 
     HtmlPage.Window.Navigate(new Uri(url)); 
    } 
    _downClickTime = null; 
}

我找到了這種要求的解決方案。希望它可以幫助ohers

      <DiscreteObjectKeyFrame KeyTime="0" Value="Visible" />

          </vsm:VisualState>

        </vsm:VisualStateManager.VisualStateGroups> 

        <!--<TextBox Margin="{TemplateBinding Padding}" Foreground="{TemplateBinding Foreground}" 
           IsReadOnly="True" 
           x:Name="SelectingText" 
           Text="{TemplateBinding Content}" Opacity="0" />--> 

        <TextBox x:Name="SelectingText" Background="Transparent" Foreground="Transparent" FontWeight="{TemplateBinding FontWeight}" 
          FontStyle="{TemplateBinding FontStyle}" FontSize="{TemplateBinding FontSize}" FontFamily="{TemplateBinding FontFamily}" IsReadOnly="True" 
          Margin="{TemplateBinding Padding}" 
           Text="{TemplateBinding Content}" Opacity="0" 
          /> 

        <TextBlock HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" x:Name="UnderlineTextBlock" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Visibility="Collapsed" Text="{TemplateBinding Content}" TextDecorations="Underline" Foreground="{TemplateBinding Foreground}" /> 
        <TextBlock HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" x:Name="DisabledOverlay" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Visibility="Collapsed" Canvas.ZIndex="1" Foreground="{StaticResource DisabledColor}" Text="{TemplateBinding Content}" /> 
        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" x:Name="contentPresenter" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}" /> 
        <Rectangle x:Name="FocusVisualElement" IsHitTestVisible="false" Opacity="0" Stroke="{StaticResource SecondaryBrush}" StrokeThickness="1" /> 

       </Grid>

在下劃線替換文字塊的文本框，並在鼠標移動
