clipboard in silverlight

I was searching for 开发者_StackOverflow社区how to implement clipboard in silverlight.

I used this link for designing clipboard.

http://www.jeff.wilcox.name/2008/05/clipboard-access/

But it shows error on this line:

HtmlPage.Window.Alert(HostNoClipboard);

and

(ScriptObject)HtmlPage.Window.GetProperty("clipboardData");

throws null always
