GridView中加入新行方法

//向GridView中加入新行方法,即通过此控件向数据库中加入新行....
public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        dataBind();
    }

    SqlConnection con = new SqlConnection("Server=.;Database=test;Integrated Security=SSPI");
    SqlCommand cmd;
    SqlDataAdapter dap;
    SqlCommandBuilder cmb;
    protected void Button1_Click(object sender, EventArgs e)
    {
        con.Open();
        cmd= new SqlCommand("select * from Users",con );
        dap = new SqlDataAdapter(cmd);
        cmb = new SqlCommandBuilder(dap);//用此法向表中加入新行是最简单的吧...
        DataSet  dst = new DataSet ();
        dap.Fill(dst, "Users");
        DataTable dt = dst.Tables["Users"];
        DataRow dro = dt.NewRow();
        dro[0] = this.TextBox1.Text;
        dro[1] = this.TextBox2.Text;
        dro[2] = Convert.ToInt32(this.TextBox3.Text);
        dst.Tables[0].Rows.Add(dro);
        dap.Update(dst, "Users");
        con.Close();
        dataBind();
    }

    public void dataBind()
    {
        con.Open();
        cmd = new SqlCommand("select *from Users",con );
        DataSet dst = new DataSet();
        dap = new SqlDataAdapter(cmd);
        dap.Fill(dst, "Users");
        this.GridView1.DataSource = dst.Tables[0].DefaultView;
        GridView1.DataBind();
        con.Close();
    }  

}

 

 我认为这是最简单一种方法...请各位高手指点一二....
