Send Text WebBrowser Forms

Hello! I have a problem when wanting to send text to a WebBrowser that abut on another Form.

This is the code that I have:

Form2:

Window wi = new Window (null, null, null, null, null, null, null);
WebBrowser bc = (WebBrowser) wi.Controls ["bodyContainer"];
bc.DocumentText = this.richText.Text;


But do not get the text, someone could enlighten me please :)

Thank you.
