RTF content in Context Menu

[Aneesh Pulukkul [http://dotnet-revolutions.blogspo]

I have a requirement- need to display RTF content in context menu. I
am able to host a rich textbox in a contextmenu strip using
ToolStripContro lHost class. But assigning some RTF content to the
containing rich textbox control does not display in actual RTF
format- it just dislpays as plain text. Here's the code am using:
//Custom richtextbox to handle bg color in readonly mode
public class MyRichTextBox : RichTextBox
{
public MyRichTextBox()
{
}

public new bool ReadOnly
{
get
{
return base.ReadOnly;
}
set
{
if (value == true)
{
this.BackColor = Color.White;
}

base.ReadOnly = value;
}
}

}

----------------------------------------------------------------
public Form1()
{
InitializeCompo nent();

m_cmenu.Items.A dd(new ToolStripMenuIt em("Edit"));
m_cmenu.Items.A dd(new ToolStripSepara tor());

MyRichTextBox m_richTextBox = new MyRichTextBox() ;
m_richTextBox.B orderStyle =
System.Windows. Forms.BorderSty le.None;
m_richTextBox.D ock = System.Windows. Forms.DockStyle .Fill;
m_richTextBox.R eadOnly = true;
m_richTextBox.S crollBars =
System.Windows. Forms.RichTextB oxScrollBars.No ne;

ToolHost textItem = new ToolHost(m_rich TextBox);
//Assign sample RTF content.
m_richTextBox.R tf = @"{\rtf1\fbidis \ansi
\ansicpg1252\de ff0\deflang1033 {\fonttbl{\f0\f swiss\fprq2\fch arset0

m_cmenu.Items.A dd(textItem);
this.ContextMen uStrip = m_cmenu;//Assign contextmenu for
