Convert the String name to Page

Hi all I am using the following to find the virtual patrh of the given form name as follows
List<string> lstFormName = new List<string>(); lstFormName.Add("WebForm1.aspx"); lstFormName.Add("WebForm2.aspx"); Page p = BuildManager.CreateInstanceFromVirtualPath("/" + lstFormName[i].ToString(), typeof(Page)) as Page; ((IHttpHandler)p).ProcessRequest(HttpContext.Current); I am using this method to find the controls in the page every thing works fine but the pages which are in list are also displaying in the current page, how can I stop loading those forms on my form or is there any option to find the controls on the page dynamically as per the above code
