C# Hyperlink in TextBlock: nothing happens when I click on it
Solution 1
You need to handle the hyperlink's RequestNavigate
event. Here's a quick way of doing it:
link.RequestNavigate += (sender, e) =>
{
System.Diagnostics.Process.Start(e.Uri.ToString());
};
Solution 2
Are you handling the 'Hyperlink.RequestNavigate' event? When a user clicks a Hyperlink in a WPF window it doesn't automatically open a browser with the URI specified in its NavigateUri property.
In your code-behind you can do something like:
link.RequestNavigate += LinkOnRequestNavigate;
private void LinkOnRequestNavigate(object sender, RequestNavigateEventArgs e)
{
System.Diagnostics.Process.Start(e.Uri.ToString());
}
Solution 3
You can make a global hyperlink handler in your App.xaml.cs
protected override void OnStartup(StartupEventArgs e) {
EventManager.RegisterClassHandler(
typeof(System.Windows.Documents.Hyperlink),
System.Windows.Documents.Hyperlink.RequestNavigateEvent,
new System.Windows.Navigation.RequestNavigateEventHandler(
(sender, en) => Process.Start(new ProcessStartInfo(
en.Uri.ToString()
) { UseShellExecute = true })
)
);
base.OnStartup(e);
}
This assumes all the NavigateUri properties refer to something you want to launch, but you can always make the handler take care of edge cases.
Solution 4
For those in .Net Core, the way you do this has changed. Based on this answer and this.
link.RequestNavigate += (sender, e) =>
{
var url = e.Uri.ToString();
Process.Start(new ProcessStartInfo(url)
{
UseShellExecute = true
});
};

In my C# standalone application, I want to let users click on a link that would launch their favorite browser.
System.Windows.Controls.TextBlock text = new TextBlock(); Run run = new Run("Link Text"); Hyperlink link = new Hyperlink(run); link.NavigateUri = new Uri("http://w3.org"); text.Inlines.Add(link);
The link is displayed correctly.
When I move the mouse over it, the link becomes red.
PROBLEM: When I click it, nothing happens.
Did I forget something? Do I need to implement some kind of method to really let the link be opened?
