0	try this once.... if (CurrencyData.Count() != 0) { foreach (var curr in CurrencyData) { decimal DollarVal = 1 / Convert.ToDecimal(curr.NAV012DollarValue); string str = Convert.ToString(DollarVal); txtDollarValue.Text = str.Substring(0,str.Length); } Substring(index, Length) means Index = 0, Length=5 If there is no data of length 5 then it will throw error Decimal to string conversion formats: // just two decimal places String.Format("{0:0.00}", 123.4567); // "123.46" String.Format("{0:0.00}", 123.4); // "123.40" String.Format("{0:0.00}", 123.0); // "123.00" Mark This Response as Answer -- Chandu http://www.dotnetfunda.com/images/dnfmvp.gif arv0307-23059, if this helps please login to Mark As Answer. \| Alert Moderator

try this once....

if (CurrencyData.Count() != 0) 

{ 

foreach (var curr in CurrencyData) 

{ 

decimal DollarVal = 1 / Convert.ToDecimal(curr.NAV012DollarValue); 

string str =  Convert.ToString(DollarVal);

txtDollarValue.Text = str.Substring(0,str.Length);  }

Substring(index, Length) means Index = 0, Length=5
If there is no data of length 5 then it will throw error

Decimal to string conversion formats:
// just two decimal places
String.Format("{0:0.00}", 123.4567); // "123.46"
String.Format("{0:0.00}", 123.4); // "123.40"
String.Format("{0:0.00}", 123.0); // "123.00"
