You can override OnPreInit in your default.aspx.cs and set the master page based on some value in your querystring. Something like this:

protected override void OnPreInit(EventArgs e)
    {
        base.OnPreInit(e);
        if (Request.QueryString["Master"] == "Simple")
            MasterPageFile = "~/Masterpages/Simple.Master";
    }

EDIT: the cause of your error message might be covered by this question.

I tried it already, But the following error msg occurs while occurs: Content controls have to be top-level controls in a content page or a nested master page that references a master page. System.Web.HttpException: Content controls have to be top-level controls in a content page or a nested master page that references a master page. – Developer404 Oct 09 '09 at 09:14

I Left the ContentPlaceholder to add on it.. Actually , I tried to assign master page without using ContentPlaceHolder.. Now, I realised that, atleast one ContentPlaceholder should be there temporarily, even though we will change the master page dynamically...
