Sql 过程在插入和更新ASPXgridview时传递空值

我写了一个程序如下

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)

然后，我将该过程用作ASPX Gridview DEV Express的插入查询

我还有一个类似的插入程序

但在这两种情况下，我输入的所有值都被传递为Null，并且我得到一个错误，无法为列CC_ID插入Null，通过使用SQL Server Pofiler，我发现所有值都以“Null”的形式发送到SQL Server。请帮助我，我已经尝试了我所知道的一切

这是ASP.net中的错误，插入时无法将值NULL插入到“cc_id”列、表“Farm_Project.dbo.Prod1”中；列不允许空值。插入失败。语句已终止。实际上SP工作正常，但从aspx发送的值为空。那么为什么要发布SP？是的，SP工作得很好，我如何解决空值问题。因为我确实输入了值，但仍然得到Null并且语句被终止。您的过程是否引发异常？？？请显示调用存储过程的代码，否则无法看到问题可能在哪里
