A:
Everything is possible. But if you are after to create a project like CMS, it's not right approach. You have to store the pages' information (such as title, description and etc.) in a data store. Thus, you have merely a single page.

May be my code can help you with this
Controller and descendant of ViewPage:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Web;
using System.Web.Mvc;
using System.Web.UI;
using System.Web.UI.WebControls;
using Site.Models;
using System.Text.RegularExpressions;
using System.Web.Mvc.Html;
namespace Site.Controllers
{
public class MPSViewPage : ViewPage
{
// Here master page is being seted
protected override void OnPreInit(EventArgs e)
{
Random rnd = new Random();
int i = rnd.Next(0, 20);
string masterPageName = (i % 2) == 0 ? "Admin.Master" : "Main.Master";
string pathMasterPageFile = "~/Views/Shared/" + masterPageName;
MasterPageFile = pathMasterPageFile;
base.OnPreInit(e);
}
protected override void OnInitComplete(EventArgs e)
{
//List of ContentPlaceHolder's id is being got. See later
MasterPageAnalizer analizer = new MasterPageAnalizer();
IList<string> contentHolders = analizer.GetBodyPlaceholders(Regex.Match(MasterPageFile, "[^/]*$").ToString());
//Add content to ContentPlaceHolder
foreach (string holder in contentHolders)
{
ContentPlaceHolder placeHolder = (ContentPlaceHolder)Master.FindControl(holder);
if (placeHolder != null)
{
Content content = new Content();
placeHolder.Controls.Add(content);
//Set function for render each content
content.SetRenderMethodDelegate(RenderIndexDeletegate);
}
}
base.OnInitComplete(e);
}
protected void RenderIndexDeletegate(HtmlTextWriter w, Control c)
{
//You can use any html helpers for rendering content
w.Write("Render to <b>" + ((Content)c).Parent.ID +
"</b> url: " + Request.Params["URL"] +
" with query parameter " + ViewData["parameters"] + " <br />" +
Html.Action("GetHtmlStatic", "HtmlStatic", new{area = "HtmlStatic"}));
}
}
public class IndexController : Controller
{
public ActionResult Index(string parameters)
{
ViewData["parameters"] = parameters;
return View();
}
}
}
Master page analizer:
using System;
using System.Collections.Generic;
using System.Linq;
using System.IO;
using System.Text.RegularExpressions;
namespace Site.Models
{
public class MasterPageAnalizer
{
private DirectoryInfo dirInfo = new DirectoryInfo(AppDomain.CurrentDomain.BaseDirectory + "Views\\Shared\\");
public IList<string> MasterPages{
get
{
IList<String> masterPageNames = new List<string>();
FileInfo[] files = dirInfo.GetFiles("*.Master");
foreach (FileInfo file in files)
{
masterPageNames.Add(file.Name);
}
return masterPageNames;
}
}
public IList<string> GetBodyPlaceholders(string masterPageName)
{
IList<string> placeholders = new List<string>();
string masterPagePath = dirInfo + masterPageName;
if (File.Exists(masterPagePath))
{
string masterPageContent = File.ReadAllText(masterPagePath);
Regex expression = new Regex(@"<asp:ContentPlaceHolder.*?ID=""(?<placeHolderId>\w+)"".*?>");
masterPageContent = Regex.Match(masterPageContent, "<body>(.|\n)*</body>",RegexOptions.Multiline).ToString();
MatchCollection matches = expression.Matches(masterPageContent);
foreach (Match match in matches)
{
placeholders.Add(match.Groups["placeHolderId"].Value);
}
}
return placeholders;
}
}
}
Simple view:
<%@ Page Title="" Language="C#" Inherits="Site.Controllers.MPSViewPage" %>
Good Luck.
