数据填充到GridView

[c#]代码库

//查询返回直接是数据        
protected void Button3_Click(object sender, EventArgs e)
        {
            DataSet ds = new DataSet();
            ds = Common.NoPager2("test", "", "News", "", "id=" + TextBox3.Text + "");
            GridView2.DataSource = ds;
            GridView2.DataBind();
        }


//先填充到SqlDataAdapter
    protected void Page_Load(object sender, EventArgs e)
    {
        SqlConnection sqlconn = c1.sqlcon();
        sqlconn.Open();
        DataSet ds = new DataSet();
        SqlDataAdapter sda = new SqlDataAdapter("select * from test", sqlconn);
        sda.Fill(ds);
        GridView1.DataSource = ds;
        GridView1.DataBind();
        sqlconn.Close();
    }
