- WebBrowser - 可以顯示, 但限定在 Out of Browser 的模式
- RichTextBox - 無法顯示 HTML
- HTML Host Control - 即在 Silverlight 上, 疊一個 position:absolute 的區塊或 ifarem
- Liquid RichTextBox - 勉強可以, 有些 HTML 的語法無法呈現, 對中文的支援更糟
- HtmlTextBox - 同樣是勉強可用

其中 HTML Host Control 應該是相容性最不受限的方法，
但嚴格來說，這不能算是 Silverlight 所提供的功能。
下列class，可以輸入InnerHtml，來顯示 HTML 的內容
但記得在包含 Silverlight 的網頁上，加入 id 為 winContent 的 div
並將 Silverlight 物件設為 windowless。
public partial class HtmlHostControl : UserControl
{
public string InnerHtml
{
get { return m_InnerHtml; }
set
{
m_InnerHtml = value;
if (m_DivIFrameHost != null)
m_DivIFrameHost.SetProperty("innerHTML", value);
}
}
public HtmlHostControl()
{
InitializeComponent();
SizeChanged += new SizeChangedEventHandler(HtmlHostControl_SizeChanged);
CompositionTarget.Rendering += new EventHandler(CompositionTarget_Rendering);
}
void CompositionTarget_Rendering(object sender, EventArgs e)
{
ResetHtmlHostPosition();
}
void HtmlHostControl_SizeChanged(object sender, SizeChangedEventArgs e)
{
ResetHtmlHostPosition();
}
HtmlElement m_DivIFrameHost = null;
string m_InnerHtml = "";
public void Show()
{
if (m_DivIFrameHost == null)
{
HtmlDocument doc = HtmlPage.Document;
m_DivIFrameHost = doc.GetElementById("winContent");
m_DivIFrameHost.SetStyleAttribute("visibility", "visible");
m_DivIFrameHost.SetProperty("innerHTML", "Hello");
}
ResetHtmlHostPosition();
}
private void ResetHtmlHostPosition()
{
if (m_DivIFrameHost != null)
{
GeneralTransform generalTransform = HtmlHostPanel.TransformToVisual(Application.Current.RootVisual);
Point pos1 = generalTransform.Transform(new Point(0, 0));
Point pos2 = generalTransform.Transform(new Point(HtmlHostPanel.ActualWidth, HtmlHostPanel.ActualHeight));
m_DivIFrameHost.SetStyleAttribute("left", pos1.X.ToString() + "px");
m_DivIFrameHost.SetStyleAttribute("top", pos1.Y.ToString() + "px");
m_DivIFrameHost.SetStyleAttribute("width", (pos2.X - pos1.X).ToString() + "px");
m_DivIFrameHost.SetStyleAttribute("height", (pos2.Y - pos1.Y).ToString() + "px");
}
}
public void ReleaseAll()
{
CompositionTarget.Rendering -= CompositionTarget_Rendering;
if (m_DivIFrameHost != null)
m_DivIFrameHost.SetStyleAttribute("visibility", "hidden");
}
}
