关于GridView的分页问题

Question

我没有为GridView中绑定数据源，而是用代码实现的搜索，但是他就不支持分页啦
System.NotSupportedException: 数据源不支持服务器端的数据分页。
怎么弄。
我是用void showAll（）方法绑定显示的数据 void showAll()
    {
        SqlConnection conn = new SqlConnection();
        conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
        SqlCommand cmd = new SqlCommand();        cmd.Connection = conn;
        cmd.CommandText = "Select MP_ID,MP_Name,MP_Address,MP_Phone,MP_Email from MO_MP";
        conn.Open();
        SqlDataReader reader = cmd.ExecuteReader();        this.myGrid.DataSource = reader;
        this.myGrid.DataBind();        reader.Close();
        conn.Close();
    }
而且用的代码实现搜索
protected void MP_Search_Click(object sender, EventArgs e)
    {
        string key = this.MP_txtKey.Text.Trim();        if (key != "")
        {
            SqlConnection conn = new SqlConnection();
            conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);            SqlCommand cmd = new SqlCommand();
            cmd.CommandText = "Select MP_Name,MP_Address,MP_Phone,MP_Email from MO_MP ";
            //按条件搜索
            cmd.CommandText += "where MP_Name like'%" + key + "%' ";
            cmd.CommandText += "or MP_Address like'%" + key + "%' ";
            cmd.CommandText += "or MP_Phone like'%" + key + "%' ";
            cmd.CommandText += "or MP_Email like'%" + key + "%' ";
            cmd.Connection = conn;            conn.Open();
            SqlDataReader reader = cmd.ExecuteReader();            this.myGrid.DataSource = reader;
            this.myGrid.DataBind();            reader.Close();
            conn.Close();
        }
        else
        {
            showAll();
        }
    }
就没办法分页啦!

这是我写的Repeater分页，大同小异，希望对你有好处.
