a real pickle with & character

Hi I'm really stuck.. I'm trying to insert an & character into a database.
When I have a textbox that says for example   "this person & that person"
 when I add it to the database its only adding "this person"
 
I have tried this:
eventName = txtEventName.Text.Replace("&", "&&")
 but it doesn't work.
 
anybody know how?
 
thanks
