Clickable Url in Twitter - windows-phone-7

Question

i have implemented a simple twitter reader in my app. I am able to get the tweets of a
user. But, if there is a url in this tweet, i cant click on it, as its not detected as an URL.
Is there a possibility to implement this function, so that urls in the tweet are displayed
as clickable url, and then launch for example a webbrowser?
Thank you very much

I assume you are using a TextBlock to show the tweet text, correct? If so, change it to a RichTextBox and all you need to do is use Run for text and Hyperlink for the links!
Also, make sure you set the IsReadOnly property of the RichTextBox to true in order for it to work properly!
Next, parse the tweet text with a regular expression to find links, and use the Hiperlink class to create a clickable link on it, and Run on the remaining text!
Here's a sample function that will parse a tweet and build the content for a RichTextBox:
private Block ParseTweet(string tweetText)
{
var paragraph = new Paragraph();
var lastIndex = 0;
foreach (Match m in Regex.Matches(tweetText, #"(http(s)?://)?([\w-]+\.)+[\w-]+(/\S\w[\w- ;,./?%&=]\S*)?"))
{
if (m.Index > 0)
paragraph.Inlines.Add(tweetText.Substring(lastIndex, m.Index));
var hyperlink = new Hyperlink()
{
NavigateUri = new System.Uri(m.Value, System.UriKind.RelativeOrAbsolute),
TargetName = "_blank"
};
hyperlink.Inlines.Add(m.Value);
paragraph.Inlines.Add(hyperlink);
lastIndex = m.Index + m.Length;
}
if (lastIndex < tweetText.Length)
paragraph.Inlines.Add(tweetText.Substring(lastIndex));
return paragraph;
}
You should call this function like so:
var tweetText = #"Testing: http://twitter.com -> link for twitter";
MyRichTextBox.Blocks.Add(ParseTweet(tweetText));

I think it's not possible but but you can parse your text to find URL (with regex) and display a hyperlink below the text.
1) you search for URLs in the text with a regex
2) if a URL is found, you create a HyperlinkButton with this URL
