Add text into richtextbox

Debug shows that my text in the object is rtf formatted but then I try adding it to the richtextbox, the text loses its format; so, only plain text is displayed


rich.SelectAll();
rich.Clear();
rich.AppendText(t);

I also try using the following code, but it fails at the assignment

rich.SelectAll();
rich.Clear();
rich.SelectionRTF=t;

Any help please..

Can you be a little more specific about your problem? Because I can't seem to understand what your dilemma is.
