I have this code courtesy of Alex Angas in Programmatically instantiate a web part page in Sharepoint. I already posted this question on stackoverflow but didn't get any answer so I decided to transfer my question here.

In my _catalogs/masterpage folder, I have 2 masterpages namely:

  1. default.master
  2. mobilepage.master

I wanted to modify the code below in such a way that I could set the masterpage instead of default.master, I will make it to mobilepage.master which is created specifically for Mobile.aspx

This code below creates a mobile.aspx file inside the document library. My only problem is how to specify the masterpage of the mobile.aspx?

string newFilename = "Mobile.aspx";
string templateFilename = "spstd1.aspx";
string hive = SPUtility.GetGenericSetupPath("TEMPLATE\\1033\\STS\\DOCTEMP\\SMARTPGS\\");
FileStream stream = new FileStream(hive + templateFilename, FileMode.Open);
using (SPSite site = new SPSite("http://sharepoint")){
using (SPWeb web = site.OpenWeb())
    SPFolder libraryFolder = web.GetFolder("Document Library");
    SPFileCollection files = libraryFolder.Files;
    SPFile newFile = files.Add(newFilename, stream);

Please help me modify the code above. I would gladly appreciate your help. Thanks!

  • Are you trying to set the master page for Mobile.aspx to be mobilepage.master? – Chakkaradeep Chandran Sep 19 '11 at 9:39
  • yes :) hope you can help me – Carls Jr. Sep 19 '11 at 9:50

I hope your Mobile.aspx is an Application Page. In application pages, you can set the master page either in the .aspx with the MasterPageFile attribute:

<%@ Page Language="C#" AutoEventWireup="true"
MasterPageFile="_catalogs/mobilemaster.master" %>

Or in the application page code behind, where your code may come to use:

this.Page.MasterPageFile = "custom master url";
  • Mobile.aspx is a webpart page, and it is created on the fly based on the web part page template. I don't think I can do that :( do you have any other option? – Carls Jr. Sep 19 '11 at 10:14
