我正在使用 devexpress，我有两个问题。

我的插入存储过程工作正常。

我指定了ASPxGridView.KeyFieldName属性。

  1. 问题在于delete存储过程。我得到错误Procedure or function 'delete' expects parameter '@id', which was not supplied.

  2. 第二个问题是update存储过程。我得到错误Procedure or function updatetable has too many arguments specified.

我的源代码：

// sql脚本

USE [Data]
GO
/****** Object: StoredProcedure [dbo].[deletetable] Script Date: 06/12/2012 
17:11:07   ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- Batch submitted through debugger: SQLQuery3.sql|0|0|C:\Users\Ali\
AppData\Local\Temp\~vsBA26.sql
ALTER procedure [dbo].[deletetable]
@id int
as
delete from Tablo where id= @id



USE [Data]
GO
/****** Object: StoredProcedure [dbo].[updatetable] Script Date: 06/12/2012 
17:13:52 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- Batch submitted through debugger: SQLQuery5.sql|0|0|C:\Users\Ali
\Desktop\SQLQuery5.sql
ALTER procedure [dbo].[updatetablo]
@name VARCHAR(50),
@surname VARCHAR(50),
@job VARCHAR(50),
@age INT,
@id INT

as
UPDATE Table
set name= @name, surname= @surname, job= @job, age= @age
where (id= @id)

谁能看到问题可能是什么，或者给我一个关于如何解决这个问题的提示？

如果您指定了DataKeyNames，请不要使用

<asp:Parameter...>

而是尝试使用：

<asp:ControlParameter Name="ID" ControlID="YourGridViewName" PropertyName="SelectedDataKey.Value" />

如果你想使用asp:parameter.../那么你应该使用SqlDataSource 的删除、插入或选择事件并实现以下操作：

protected void yourDataSource_deleting(object sender, ObjectDataSourceMethodEventArgs e)
{
     e.InputParameters["yourParameterName"] = value;
}
