Question

I’m new to Silverlight and want to display some HTML inside a Silverlight App. I’ve been reading about some ways to do it like the HTMLPlaceHolder from Telerik or HTML Overlays by mixing some css and javascript with the app.

The problem is that both require me to set the windowless=true which after going through its limitations on:

http://blogs.msdn.com/b/silverlight_sdk/archive/2008/11/12/limitations-of-windowless-mode-for-silverlight.aspx

I don’t think will be worthily so, are there any ways to display HTML without the windowless set to true?

Thanks in advance for the assistance..

I’m using the RadRichTextBox from Telerik which lets you render pretty much any type of document.

Herzmeister, thanks a lot for your answer, after looking at the code of the HTMLTextBlock you suggested I could come up with a solution.. here’s the code I used..

.xaml

<UserControl x:Class="RadControlsSample.RadRichTextBoxTest"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"            
    xmlns:telerikHtml="clr-namespace:Telerik.Windows.Documents.FormatProviders.Html;assembly=Telerik.Windows.Documents.FormatProviders.Html"
    mc:Ignorable="d" d:DesignWidth="700" d:DesignHeight="400" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"
    Loaded="Example_Loaded">

    <Grid x:Name="LayoutRoot">
        <telerik:RadRichTextBox Grid.Row="1" x:Name="richTextBox" DataContext="{Binding}" IsReadOnly="True" ShowMergeFieldsHighlight="False" IsSpellCheckingEnabled="False" />
    </Grid>
</UserControl>

.cs

using System;
using System.IO;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Resources;
using Telerik.Windows.Documents.FormatProviders.Html;
using Telerik.Windows.Documents.Model;

namespace RadControlsSample
{
    public partial class RadRichTextBoxTest : UserControl
    {
        private const string SampleDocumentPath = "SampleData/SomeHtml.html";

        public RadRichTextBoxTest()
        {
            InitializeComponent();
        }

        private void Example_Loaded(object sender, RoutedEventArgs e)
        {
            //Load html file from the content file
            var fileUri = new Uri(SampleDocumentPath, UriKind.Relative);
            StreamResourceInfo streamInfo = System.Windows.Application.GetResourceStream(fileUri);
            var reader = new StreamReader(streamInfo.Stream);
            this.richTextBox.Document = new HtmlFormatProvider().Import(reader.ReadToEnd());
            this.richTextBox.Document.LayoutMode = DocumentLayoutMode.Flow;
        }
    }
}
