Hi, I am using LLBLGen 2.0 using Net2.0 and SQLServer2005. I converted from LLBLGen1.0 to 2.0. Now i am getting all over the projects the error "Nullable object must have a value".I am assgning the DAL values to textboxes.Then i am getting the error.

Please anyone can help me out..

Thanks in advance,

Balaji

Can you post the code that is causing the errors and when the error is being thrown?

Hi, Here is the code:

EntitydataEntity DALEntityData = new EntitydataEntity(Convert.ToDecimal(strPkID));

objEntityData.TurnOver = DALEntityData.Turnover.Value;

objEntityData.OtherOperatingIncome = DALEntityData.OtherOperatingIncome.Value;

When i assign the DALEntitydata value to myobject(objEntitydata) it's giving the "Nullable object must have a vale".

I am converting LLBLGen 1.1 VStudio 2003 project to LLBLGen 2.0 Vstudio2005 project using target platform 2.0.

Can you please suggest me how to solve this? It's a urgent one...

Thanks in advance, Balaji

There are some information missing in your form, please read the following guide: http://www.llblgen.com/TinyForum/Messages.aspx?ThreadID=7722

I'm assuming you are using the SelfServicing model. You did not specify which line of code produces the exception/error.

Thanks in advance, Balaji

change: objEntityData.TurnOver = DALEntityData.Turnover.Value; into if(DALEntityDaata.Turnover.HasValue) { objEntityData.TurnOver = DALEntityData.Turnover.Value; }

The reason for this is that Turnover is a nullable type. Please read more about nullable types in the .NET 2.0 C# documentation. If you don't want nullable types, please uncheck the checkbox in teh designer for this field or run the plugin to bulk-set this flag for all your fields.
