看了下国外某巨牛的BLOG，大概是讲asp.net 2.0中用GRIDVIEW插入新记录的，方法比较特别，但效果一般，故将程序转之，较为简单，不做解释等。
<%@ Page Language="C#" ClassName="Default_aspx" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

<script runat="server">
void CancelButton1_Click(object sender, EventArgs e)
{

GridView1.ShowFooter = false;

}
void AddButton1_Click(object sender, EventArgs e)
{

GridView1.ShowFooter = true;

}

void Button1_Click(object sender, EventArgs e)

{

TextBox customerID = GridView1.FooterRow.FindControl("CustomerIDTextBox") as TextBox;

TextBox companyName = GridView1.FooterRow.FindControl("CompanyNameTextBox") as TextBox;

DropDownList ContactTitle = GridView1.FooterRow.FindControl("ContactTitleDropDownList") as DropDownList;

SqlDataSource1.InsertParameters["CustomerID"].DefaultValue = customerID.Text;

SqlDataSource1.InsertParameters["CompanyName"].DefaultValue = companyName.Text;

SqlDataSource1.InsertParameters["ContactTitle"].DefaultValue = ContactTitle.SelectedValue;

SqlDataSource1.Insert();

}
