richtextbox databinding saving and reloading formated rtf

Question

ok I have a c# windows forms program that I am making in Visual Studio 2013

I had a text box set to databinding text property to a table in my sql database

using  a dataset

so my data was auto saved from text box to the database and read back to textbox

now

I needed to change my textbox to a richtextbox so that I could bold, change color etc.. the font.

I do not see how to bind and read back the rtf property using databinding

I tried this

 

notesRichTextBox.DataBindings.Add(new Binding("Rtf", MyProgramDataSet.RTFTable, "RTF"));

but it only put some rtf data in the colomn and displayed nothing back in the richtextbox when I reopened the form

I tried setting the notesRichTextBox.Text = notesRichTextBox.Rtf and it just showed all of the underlying rtf code/text

 

Please help

I also tried at the beginning to set the databinding using the VisualStudio interface but Rtf doesn't seem to be an option
