Thanks for this control, but it is not working for me. I tried to add it to a databound listbox and it wouldn't show up.

My listbox item temple looks like this:

<Grid Height="90" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"

Visibility="Visible">

<TextBlock x:Name="txtSummary2" Text="{Binding Summary}" TextWrapping="Wrap"

HorizontalAlignment="Stretch" MinWidth="200"></TextBlock>

<local:HtmlTextBlock x:Name="txtSummary" Text="{Binding Summary}" TextWrapping="Wrap"

HorizontalAlignment="Stretch" MinWidth="200">

</local:HtmlTextBlock>

<!--<local:HtmlTextBlock x:Name="txtContent" Text="{Binding Content}"

TextWrapping="Wrap" HorizontalAlignment="Stretch"

MinWidth="200" UseDomAsParser="true"></local:HtmlTextBlock>-->

</StackPanel>

</Grid>

</DataTemplate>

eibrahim,

This is a consequence of me doing as simple a port as possible. :( Recall that Silverlight 1.1 Alpha did not support data binding, so this issue simply couldn't exist there. Now that Silverlight 2 Beta 1 supports data binding, HtmlTextBlock needs a minor change to support it. In particular, its properties need to be backed by DependencyProperties in order for data binding to work as we'd like. I'll be updating the sample soon to add this support, but for now if you go ahead and replace the Text property definition of the HtmlTextBlock class with the following, then your scenario should work fine:

public static DependencyProperty TextProperty = DependencyProperty.Register("Text", typeof(string), typeof(HtmlTextBlock),

delegate(DependencyObject o, DependencyPropertyChangedEventArgs e) { ((HtmlTextBlock)o).ParseAndSetText((string)(e.NewValue)); });

public string Text

{

get { return (string)GetValue(TextProperty); }

set { SetValue(TextProperty, value); }

}

Please let me know if this doesn't solve the problem!
