How to make the URL in textblock be clickable? - silverlight

Question

The content of the textblock is imported from a web service, but somehow there is a URL.
Is it possible to make it a link?
Thanks.

Answer 1

Sounds like you want a LinkLabel control. I've used that control with some modifications in my Silverlight Twitter Badge to mix the text and links that show up in tweets.
If you just have a TextBlock with a link only and want that clickable then you just set the cursor to be a hand and add an event handler for the MouseLeftButtonDown event that would navigate to the value of the TextBox.
Xaml:
<TextBlock Text="http://www.microsoft.com" Cursor="Hand" TextDecorations="Underline" MouseLeftButtonDown="TextBlock_MouseLeftButtonDown" />
Code:
private void TextBlock_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
var txt = ((TextBlock)sender).Text;
System.Windows.Browser.HtmlPage.Window.Navigate(new Uri(txt, UriKind.Absolute));
}

You could do something like the following; however this makes use of a Label and not a textblock.
In your XAML you do the following:
<dataInput:Label Grid.Row="2">
<ContentPresenter>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Hello world"/>
<HyperlinkButton x:Name="Test" NavigateUri="{Binding Path=URI}" Content="This is a url"/>
</StackPanel>
</ContentPresenter>
</dataInput:Label>
and in your code behind you add the following dependency property and set the datacontext to the page itself
public static readonly DependencyProperty URLProperty =
DependencyProperty.Register("URI", typeof(Uri), typeof(MainPage), null);
public Uri URI { get
{
return (Uri)GetValue(URLProperty);
}
set
{ SetValue(URLProperty, value); }
}
This code sets the dependency property for the binding to the URL;
public MainPage()
{
InitializeComponent();
URI = new Uri("/Home", UriKind.Relative);
DataContext = this;
}
This code creates a new URI and binds it to the variable. It also sets the data context to the page itself.
