How do I translate a ® into Silverlight Text Represenation

Question

I make calls to a webservice to get information that bind to the Text property of a TextBlock. Sometimes the information will contain encoded special characters for HTML - most notably the ® which I believe to the (r) symbol. The silverlight TextBlock just displays the raw text and not the (r). Of course, I can strip out the text, but it seems that someone on here will know how to translate HTMl codes like this into something that the TextBlock can understand. My first though is an iValueConverter with a Regex relace???

has anyone done one of these?

Answer 1

I believe you should be using ® and not $#174;. I'm not sure about silverlight, but WPF will translate these literals automagically.

I admit that I don't think this will necessarily work if the text property is being databound. If that's the case, then an IValueConverter will be fine. Otherwise, you can also search/replace these literals in your object before the value is bound. This can be accomplished in your ViewModel (if you're following MVVM).

Answer 2

You just need to use HtmlDecode:

System.Windows.Browser.HttpUtility.HtmlDecode(yourStringHere)

Answer 3

In HTML, entities like > refer to their decimal value in ASCII, so it is as simple as replacing the expression with its decimal value.

I've assumed that $#174; is a typo and you mean ®
