I use the  C# statement below in an aspx page to show a price

<%# AuctionRow["min_bid"].ToString() == "" ? AuctionRow["pay"] :
AuctionRow["min_bid"] %>

but it displays with 4 decimal decimal places

I thought AuctionRow["min_bid"].ToString("C") would give me 2 places but it
gives a compilation error

CS1501: No overload for method 'ToString' takes '1' arguments

in the aspx.cs i am using

using System.Globalization;

and in web.config  file i have

<globalization culture="en-AU" uiCulture="en" requestEncoding="UTF-8"
responseEncoding="UTF-8" fileEncoding="UTF-8"/>

in the system.web section

Can any one tell me where and what I need to add to get the string to
display as currency

Thanks
