Pulling data from database

Hi I wonder if anyone can help me.

I am trying to create a pageBase class where I can dynamically pull data from the database and display it on a web page. Each page I specifically set an ID for the sql query which pulls back the information such as page title and page text.

my problem is that I can’t seem to pass the information captured from the query to the page. I get problems such as can’t convert string type to literal and I need to declare a new keyword to an object.

PageBase Class

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Configuration;
using System.Data.SqlClient;

public class PageBase : Page

    public int PageId { get; set; }
    protected Literal contentHeader;
    protected Literal contentText;

    protected override void OnLoad(EventArgs e)
        SqlConnection conn;
        SqlCommand comm;
        SqlDataReader reader;
        string connectionString =
        conn = new SqlConnection(connectionString);
        comm = new SqlCommand("SELECT m_name, m_text, m_id FROM pages WHERE m_id = " + PageId, conn);

            reader = comm.ExecuteReader();
            if (reader.Read())
                contentHeader.Text = "<h1>" + Server.HtmlEncode(reader["m_name"].ToString()) + "</h1>";
                contentText.Text = Server.HtmlEncode(reader["m_text"].ToString());


My Code Behind on page

public partial class _Default : PageBase
        protected override void OnInit(EventArgs e)

            this.PageId = 2;
            this.contentHeader = this.ltlHeader;
            this.contentText = this.ltlContent;

my page

<asp:Literal runat="server" id="ltlHeader" /> 
       <div><p><asp:Literal runat="server" id="ltlContent" /></p></div>

I think it something to do with passing a string value but even if I just pass the value it gives an error.

can someone help or give me advise? btw I am still learning asp.net.

Thank you for your reply.
I have tried this but I get this error…

Error 1 Cannot implicitly convert type ‘System.Web.UI.WebControls.Literal’ to ‘string’

Line 15: this.contentHeader.Text = this.ltlHeader;


this.contentHeader = this.ltlHeader;
this.contentText = this.ltlContent;

Should be this:

this.contentHeader.Text = this.ltlHeader;
this.contentText.Text = this.ltlContent;

Sorry, I also forgot to tell you to change:

protected Literal contentHeader;
protected Literal contentText;


protected string contentHeader;
protected string contentText;

Then in the reader remove the .Text property
