<asp:Literal id="Literal1" runat="server"></asp:Literal>

use javascript:
<scrip language="javascript">
<!--
function formatCurrency(num) {
                  d=new Date()
                  if (d.getTimezoneOffset( ) > 60) currSign='$'
                  else currSign='£'

                  num = num.toString().replace(/\$|\,/g,'');
                  if(isNaN(num))
                        num = "0";
                  sign = (num == (num = Math.abs(num)));
                  num = Math.floor(num*100+0.50000000001);
                  cents = num%100;
                  num = Math.floor(num/100).toString();
                  if(cents<10)
                        cents = "0" + cents;
                  for (var i = 0; i < Math.floor((num.length-(1+i))/3); i++)
                        num = num.substring(0,num.length-(4*i+3))+','+
                              num.substring(num.length-(4*i+3));
                  return (((sign)?'':'-') + currSign + num + '.' + cents);
            }
//-->
</script>

Then inside your Page_Load put the following code:

Literal1.Attributes.Add("onload","javascript:formatCurrency(this.value);")

Hi,

The easiest way to do it would be to use String's Format method. This is a working example from the server side.

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim value As Integer = 10003 'This would be the value you want to display

        Literal1.Text = String.Format("{0:c}", value) 'More details about this following

End Sub

The result would be a literal displaying

$10,003.00

The String.Format method thakes two arguments by default: the first is the format string, and the second is the object wich will be formated, it can be anything such as the integer in the example or an array.

The format string is written in the following form "{0:c}" where 0 means the index of the value you'll format from the object you're passing, it's commonly 0 as you'll be passing a single value hence it's array index is zero. The ":c" part is where you specify you want the object formatted as currency, what the server will do is check for its country code and will format according to it's country currency standards.

There are more format strings, like d, "{0:d}" would display the value as a date.

At last, you can get the same result with this other form:

   Literal1.Text = value.toString("C") '<--- this will automatically format the value as a currency string
