Procedure Passes Null Values on inserting and Update ASPXgridview

Question

I wrote a procedure as follows

USE [Farm_Project]
GO
/****** Object:  StoredProcedure [dbo].[prod1_insert]    Script Date: 11/12/2014 1:21:20 PM      ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER proc [dbo].[prod1_insert]
(
  @coop_id int,
  @good_eggs int=0,
  @broken_eggs int=0,
  @small_eggs int= 0,
  @date smalldatetime=null

  )
  AS
  if @date is null
  set @date=getdate()

  insert into Prod1 (cc_id,  gd_Eggs,   br_Eggs,   sm_Eggs,  Prod_date  )
  values
                  (@coop_id  ,@good_eggs,  @broken_eggs, @small_eggs,@date)

Then I use the procedure as an Insert Query for ASPX Gridview (DEV Express)

Also I have a similar procedure for insert.

But in both cases all values I enter are being passed as Null and I get an Error "Cannot insert Null for Column CC_ID", and by using SQL Server Pofiler I found out that all values are being sent to SQL server as 'null'. Please help I have tried all that I know.

Thank you in advance.
