How can I set the text of a WPF Hyperlink via data binding?

📝 Tech Blog: The Magic of Data Binding with WPF Hyperlinks 🌟

Are you a WPF enthusiast looking to set the text of a Hyperlink using data binding? 🤔 Don't worry, you're not alone! Many programmers have faced this issue when trying to create dynamic hyperlinks with clickable text in WPF. But fear not, we're here to help! 💪

Let's dive into this common problem and explore some easy solutions to make your Hyperlinks shine with data-bound text. 🌈

The Current Situation 😕

In the provided context, the challenge arises when you want to bind the text of the Hyperlink to the name of an object. 📛 Your initial intuition might be to use the Text property in conjunction with data binding, but unfortunately, the Hyperlink class lacks a suitable dependency property for that purpose. 😔

Solution 1: Utilizing the ContentPresenter 🎁

One way to overcome this challenge is to leverage the power of the ContentPresenter control within the Hyperlink tag. 🙌 This allows you to bind the content of the Hyperlink indirectly by manipulating the Content property of the ContentPresenter.

Here's an example of how you can achieve this: 👇

<TextBlock>
  <Hyperlink Command="local:MyCommands.ViewDetails" CommandParameter="{Binding}">
    <ContentPresenter Content="{Binding Name}" />
  </Hyperlink>
</TextBlock>

By using the ContentPresenter, you can bind the Content property to the Name property of your object. This will dynamically update the text of the hyperlink as the object's name changes. 🔄

Solution 2: Leverage Attached Properties 🧲

Another way to set the text of a Hyperlink via data binding is by using attached properties. This approach allows you to create a custom attached property that encapsulates the desired behavior.

To illustrate this solution, let's create a custom attached property called HyperlinkText and set its value to the desired text dynamically.

Here's an example of how you can implement this approach: 👇

public static class HyperlinkHelper
{
    public static readonly DependencyProperty HyperlinkTextProperty =
        DependencyProperty.RegisterAttached(
            "HyperlinkText",
            typeof(string),
            typeof(HyperlinkHelper),
            new PropertyMetadata(OnHyperlinkTextChanged));

    public static void SetHyperlinkText(DependencyObject obj, string value)
    {
        obj.SetValue(HyperlinkTextProperty, value);
    }

    public static string GetHyperlinkText(DependencyObject obj)
    {
        return (string)obj.GetValue(HyperlinkTextProperty);
    }

    private static void OnHyperlinkTextChanged(DependencyObject obj, DependencyPropertyChangedEventArgs e)
    {
        if (obj is Hyperlink hyperlink)
        {
            hyperlink.Inlines.Clear();
            hyperlink.Inlines.Add(new Run((string)e.NewValue));
        }
    }
}

In XAML, you can now bind the desired text to the HyperlinkText attached property, like this: 👇

...
<TextBlock>
    <Hyperlink Command="local:MyCommands.ViewDetails" CommandParameter="{Binding}"
        local:HyperlinkHelper.HyperlinkText="{Binding Name}" />
</TextBlock>
...

Voilà! 🎉 With this approach, the text of your hyperlink will update whenever the Name property of the object changes.
