HyperlinkButton Attributes - Set Underline as Style RRS feed

  • Question

  • I am working with C# and Xaml for a Windows Phone 8.1 app project, and setting attributes to a HyperlinkButton in C#;

    The below code sample is OK, except for the line: Style = newUL

    "Cannot implicitly convert type 'Windows.UI.Xaml.Documents.Underline' to 'Windows.UI.Xaml.Style'

    Any insight, guidance is appreciated;

    private HyperlinkButton GetAsLink(string tweetWord)
                SolidColorBrush solidColorBrush = new SolidColorBrush(Colors.White);
                SolidColorBrush solidColorBrushBG = new SolidColorBrush(Colors.Blue);
                double testFont = new double();
                testFont = 22;
                Underline newUL = new Underline();            
                var hl = new HyperlinkButton
                    NavigateUri = new Uri(tweetWord),
                    Foreground = solidColorBrush,
                    Content = tweetWord,
                    FontSize = testFont,
                    FontWeight = FontWeights.Bold,
                    Background = solidColorBrushBG,
                    Style = newUL
                return hl;

  • Style is essentially a collection of property settings to describe the Control. It is not related to text styling or the Document.Underline class. The Underline class can only be used within a Document type such as a TextBlock or a RichTextBlock.

    The HyperlinkButton can take any content, so you can set its content to a TextBlock using the Underline tag:

                    <Underline>Lorem ipsum</Underline>
    Adding this to your C# code (extra properties removed for simplicity)
                TextBlock tb = new TextBlock();
                Underline ul = new Underline();
                ul.Inlines.Add(new Run() { Text = tweetWord });
                var hl = new HyperlinkButton
                    NavigateUri = new Uri(tweetWord),
                    Content = tb,
