ASP.Net SDM_Master_Budget_TestTableAdapter does not exist in the type SDMDAL

Hi, In my Project I have a dataset named "SDMDAL.xsd"and I am adding "TableAdapter" named "SDM_Master_Budget_TestTableAdapter" inside "SDMDAL.xsd" dataset, wizard to bind data.

And I have created a class file (say "SDM.Budget.cs") inside which I am calling thisDataset TableAdapter, C# code is below:

using SDMDALTableAdapters; // refrence of dataset table adapter



public class SDM_BudgetTest
{
	public SDM_BudgetTest()
	{
		
	}

    private SDM_Master_Budget_TestTableAdapter _Budget_TestTableAdapter = null;
    protected SDM_Master_Budget_TestTableAdapter Adapter
    {
        get
        {
            if (_Budget_TestTableAdapter == null)
                _Budget_TestTableAdapter = new SDM_Master_Budget_TestTableAdapter();

            return _Budget_TestTableAdapter;
        }
    }

    #region GET
    public SDMDAL.SDM_Master_Budget_TestTableAdapter GetBudgetTest()
    {
        return Adapter.GetBudgetTest();
    }
    #endregion
    public void UpdateBudget(DataRow BudgetRow)
    {
        Adapter.Update(BudgetRow);
    }
    public void DeleteBudget(int ID)
    {
        Adapter.Delete(ID);
    }
    public void InsertBudget(string BfoSectionID, decimal BValueEX, decimal BValueEXBilled, decimal BValuePD, int BYear)
    {
        Adapter.Insert(BfoSectionID, BValueEX, BValueEXBilled, BValuePD, BYear);
    }

When I deploy my code to server, I get this error:

"SDM_Master_Budget_TestTableAdapter' does not exist in the type 'SDMDAL'"
