Are those code classes in the same assembly? It seems the second class can't find a definition for the first class. Also this is a bad idea:

public int ExecuteNonQuerywithMultipleTrans(SqlTransaction sqlTrans, string storedProcedure, SqlParameter[] param)
        {
            int returnResult = 0;
            try
            {
                returnResult = SqlHelper.ExecuteNonQuery(sqlTrans, CommandType.StoredProcedure, storedProcedure, param);
                return returnResult;
            }
            catch (Exception sq)
            {
                throw sq;
            }
        }

2 reasons:
1) Why even bother catching an exception if you're just going to rethrow it?
2) The code you posted boxes the exception. You never want to do that because you hide import details. If you want to rethrow an exception you should just use the throw operator:

try
      {
        throw new InvalidOperationException();
      }
      catch
      {
        throw;
      }

I had copied the code to notepad and was just shutting everything down for the evening and noticed the problem:

namespace TurnkeySolutions.App_Code.[B]DAL[/B]
namespace TurnkeySolutions.App_Code[B].BLL[/B]

You need to add using TurnkeySolutions.App_Code.DAL; to your second class file. The class definition and implementation you posted are in two different namespaces.

Thanks for suggestion. How we check my classes or not belonging to same assembly and how would I add my classes to assembly.

>>Thanks for suggestion. How we check my classes or not belonging to same assembly and how would I add my classes to assembly.

Are all of your code files in a single project or do you have a web application and other DLL projects in the solution? Can you upload the project? If you are using a DLL (I think you are) then you need to add a reference to the project or DLL in your web application. You will see a "References" node in the solution explorer. From there you can right click and add a reference. Simply copying a .NET DLL in to the execution directory will not suffice for web applications because of how the server compiles the assembly at execution time.

The all file belong to a single project in different folders. May you send your messenger id like yahoo, skype or msn. Then I would share my desktop you to would yourself check out his problem. And let me when you would be online. I am Farooq from Pakistan.

Unfortunately I don't use any messenger services. Send me a message here on the forums when you're online next (with your email) and we can get together. I have a GoToMeeting account we can use, or we can use your preferred meeting software.
