add commas using String.Format for number and
<p>Using String.Format how can i ensure all numbers have commas after every 3 digits
eg 23000 = "23,000" and that 0 returns "0".</p>

<p>String.Format("{0:n}", 0); //gives 0.00 which i dont want.
I dont want any decimal places, all numbers will be integers.</p>
