how to show Integer to Currency Value in Listview

Hi,
 I have a record money value in Integer. I need to show it is in money value.
For Ex. In 50000 shows to 50,000 or 1000 => 1,000 or 225000 => 2,25,000
<asp:Label ID="lblAmount" runat="server" Text='<%#String.Format("{0:c}", Eval("Amount")) %>' /> Help me out this problem.
