declare @negotiation_ID int
set dateformat dmy


Begin---insert negotiation

SELECT @negotiation_ID=ISNULL(MAX(negtiation_ID),0)+1 FROM negotiate


INSERT INTO negotiate (negtiation_ID,Time_Stamp, stock_ID,client_FOB_Price, Client_FrieghtPrice, Client_Vanning_Price,
 Client_Inspection_Price, Client_Total_Cost, Currency_ID,Country_ID,
  Customer_ID, Client_Name, Client_Email, Client_Phone, Client_Comments, ShipmentType)

   @Client_Name, @Client_Email, @Client_Phone, @Client_Comments, @ShipmentType);

End

Any Idea why i am getting this error although i am guessing that there are correct values

Answer 1

Int32.Parse(...) or Decimal.Parse(...) throws the exception. The first and only i see is:

Int32.Parse(ddlCurrency.SelectedValue), //  0.0105   

This is clearly not an int so use

Decimal.Parse(ddlCurrency.SelectedValue), //  0.0105   

However, in your stored-procedure this seems to be also an int because it's a currency-ID. Then you have to fix this bug. The DropDownList.SelectedValue should not be 0.0105 when it's an int-ID.

Apart from that you would also get the exception if your current culture is not using the dot . as decimal separator. Then you have to enforce this separator by using InvariantCulture :

Decimal.Parse(ddlCurrency.SelectedValue, CultureInfo.InvariantCulture)  

Answer 2

you are using Int32.Parse for parsing value like 0.0105. As you know this is not an integer value so it will throw an exception. One more thing as I can see here you are using int for @Currency_ID int. It should be also money or decimal.
