ASP中向数据库插入数据的问题！！
本人是个业余爱好者，从网上荡了个OA办公系统源码，然后自己改哦了学习。现在遇到难处了希望大家多多指教如图，提交下拉框中的数据提示出错，提示内容如下：
过程或函数 'departmentInsert' 需要参数 '@dept_parid'，但未提供该参数。
说明: 执行当前 Web 请求期间，出现未处理的异常。请检查堆栈跟踪信息，以了解有关该错误以及代码中导致错误的出处的详细信息。
异常详细信息: System.Data.SqlClient.SqlException: 过程或函数 'departmentInsert' 需要参数 '@dept_parid'，但未提供该参数。
源错误:
行 260:
行 261: //finally, execute the command.
行 262: int retval = cmd.ExecuteNonQuery();
行 263: // detach the SqlParameters from the command object, so they can be used again.
文件代码如下：
protected void Button1_Click(object sender, EventArgs e)
{
//部门名称
string bumen = this.TextBox1.Text;
//上级部门ID
//int parid = this.DropDownList1.DataValueField;
int parid = Int32.Parse(this.DropDownList1.Text);
//int parid = 3 ;
if (bumen != "")
{
if (parid != 0)
{
department dp = new department();
dp.dept_department = bumen;
dp.dept_parid = parid;
int i = departmentBLL.Insert(dp);
if (i < 0)
{
this.Response.Redirect("selectbm.aspx");
}
}
else
{
this.Response.Write("<script>window.alert ('请选择上级部门')</script>");
}
}
else
{
this.Response.Write("<script>window.alert ('请您输入标题')</script>");
this.TextBox1.Focus();
}
}
存储过程代码如下：
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go

/*
@dept_id 部门id
@dept_department 部门名称

我是实在搞不懂了，希望大大帮帮忙，看看到底是什么原因，我是初次注册上来的。20分全给大家了，谢谢了！
