HTMLTextBlock for Windows Phone 7

Question

I am trying to include an html text box in my Windows Phone 7. I see code example here. The problem is that the HTMLPage class does not exist on Windows 7, or rather, System.Windows.Browser does not exist. Does anyone know an alternative for this?

I struggled with this for all of the same reasons and eventually came up with a solution. I need to show a bunch from the inside in a ListBox for my Septic Companion application . Right now, my decision is only bold or italic (like everything I cared about), but it would be easy to change it to deal with more. First, in my ViewModel, I wrote a procedure to return a TextBlock given an HTML string.

private TextBlock MakeFormattedTextBlock(string shtml) { TextBlock tb = new TextBlock(); Run temprun = new Run(); int bold = 0; int italic = 0; do { if ((shtml.StartsWith("<b>")) | (shtml.StartsWith("<i>")) | (shtml.StartsWith("</b>")) | (shtml.StartsWith("</i>"))) { bold += (shtml.StartsWith("<b>") ? 1 : 0); italic += (shtml.StartsWith("<i>") ? 1 : 0); bold -= (shtml.StartsWith("</b>") ? 1 : 0); italic -= (shtml.StartsWith("</i>") ? 1 : 0); shtml = shtml.Remove(0,shtml.IndexOf('>') + 1); if (temprun.Text != null) tb.Inlines.Add(temprun); temprun = new Run(); temprun.FontWeight = ((bold > 0) ? FontWeights.Bold : FontWeights.Normal); temprun.FontStyle = ((italic > 0) ? FontStyles.Italic : FontStyles.Normal); } else // just a piece of plain text { int nextformatthing = shtml.IndexOf('<'); if (nextformatthing < 0) // there isn't any more formatting nextformatthing = shtml.Length; temprun.Text += shtml.Substring(0, nextformatthing); shtml = shtml.Remove(0, nextformatthing); } } while (shtml.Length > 0); // Flush the last buffer if (temprun.Text != null) tb.Inlines.Add(temprun); return tb; } 

Then I just need a way to build this in my XAML. This may not be the best solution, but I first did another procedure to return a StackPanel containing this TextBlock with the text I wanted.

 public StackPanel WordBlock { get { StackPanel sp = new StackPanel(); TextBlock tbWord = MakeFormattedTextBlock("<b>" + Word + "</b>: " + Desc); sp.Children.Add(tbWord); return sp; } } 

To bind this to a visible control, I made a DataTemplate for my ListBox, which just read the entire StackPanel from my view model.

 <DataTemplate x:Key="WordInList2"> <ContentControl Content="{Binding WordBlock}"/> </DataTemplate> 

As I said, there may be parts of it that don't work as elegantly as they can be, but that did what I wanted. Hope this works for you!

Hi, I have converted SilverlightHtmlTextBlock to WP7 here. I have not tested it for terribly complex cases and explosions on dtd tags, but it does the job for simpler html cases and sounds like you were looking for.

WebBrowser can display html.
