Use HttpHandler to do this. Just read the HTML page from the database and flush it to response stream.

Be sure to map the handler with a route in web.config

CODE: PageWriter HttpHanlder

using System;
using System.Collections.Generic;
using System.Web;

/// <summary>
/// Summary description for PageWriter
/// </summary>
public class PageWriter : IHttpHandler
{
    public PageWriter()
    {
        //
        // TODO: Add constructor logic here
        //
    }

    #region IHttpHandler Members

    public bool IsReusable
    {
        get { return true; }
    }

    public void ProcessRequest(HttpContext context)
    {
        try
        {
            string htmlPageFromDatabase = string.Empty;

            //Read the HTML Page content into htmlPageFromDatabase from database

            context.Response.Write(htmlPageFromDatabase);
        }
        catch (Exception ex)
        {
            context.Response.Write("Page could not be loaded due to " + ex.Message);
        }
    }

    #endregion
}

WEB.CONFIG

<httpHandlers>
      <remove verb="*" path="*.asmx"/>
      <add path="PageFromDatabase.aspx" verb="GET" type="PageWriter" />
</httpHandlers>

After this, You cann access your page from http://yourserver/yourapp/PageFromDatabase.aspx [ ex: http://localhost/mywebsite/PageFromDatabase.aspx ]

You could put an <asp:Literal ...> control on the page and set the Text property to be the text from the database.

Or if you really what the whole page contents to come from a database, you could create an .ashx HttpHandler and do a Response.Write() to write the HTML back to the response stream. Something like this should work:

public void ProcessRequest(HttpContext context)
{
    int id = 0;

    if (context.Request.QueryString["id"] != null)
        int.TryParse(context.Request.QueryString["id"], out id);

    if (id != 0)
    {
        var con = new SqlConnection("myconnectionstring");
        var cmd = new SqlCommand("SELECT html FROM mytable WHERE id = @id", con);
        cmd.Parameters.Add("id", id);

        object html = cmd.ExecuteScalar();

        if (html != null)
            context.Response.Write(html);
    }
    else
        context.Response.Write("No content found");
}

---

Try this:

string newHtml = "...";
Response.Clear();
Response.Write(newHtml);
Response.End();

What kind of html is on the page? Does it have a masterpage? Why is there html on the page that you are replacing?

You could override the Render event of the page and write out the html.

protected override void Render(HtmlTextWriter writer)
{
    writer.Write(newHtmlGoesHere);
}
