It must be smaller than the current number of View controls '1'. For dynamically added views, make sure they are added before or in Page_PreInit event. Parameter name: value)

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            m1.ActiveViewIndex = 0;
        }
        if (m1.ActiveViewIndex==0)
        {
            Button2.Visible = false;
        }

    }


protected void Button1_Click(object sender, EventArgs e)
{

    con.Open();
    SqlCommand cmd = con.CreateCommand();
    cmd.CommandType = CommandType.Text;
    cmd.CommandText = "SELECT * FROM exam WHERE exam_name='" + Request.QueryString["examid"] + "'";
    cmd.ExecuteNonQuery();
    DataTable dt = new DataTable();
    SqlDataAdapter da = new SqlDataAdapter(cmd);
    da.Fill(dt);

    foreach (DataRow dr in dt.Rows)
    {
        View view = new View();
        Label label = new Label();
        RadioButtonList list = new RadioButtonList();
        label.Text = dr["qustion"].ToString();
        list.Items.Add(new ListItem(dr["cha"].ToString(), "a"));
        list.Items.Add(new ListItem(dr["chb"].ToString(), "b"));
        list.Items.Add(new ListItem(dr["chc"].ToString(), "c"));
        view.Controls.Add(label);
        view.Controls.Add(list);
        m1.Views.Add(view);
    }
    m1.ActiveViewIndex = 1;
    Button2.Visible = true;
    Button1.Visible = false;

}

protected void Button2_Click(object sender, EventArgs e)
{
    if (m1.ActiveViewIndex < m1.Views.Count)
    {
        m1.ActiveViewIndex += 1;
    }
