(I just started working with SharePoint last week excuse me if I am using some Names wrong)

I will try to explain what I have to do.

I have to change the design only of the main page of the master page

For testing I just inserted a <style> section inside of settle.master.

Now I have the final design but of course what I did is applying to all SharePoint sub sites what I don't want.

The design should be activated as Site Feature

Example of what is inside my css

/*Hide ShrePoint left navigation*/
.ms-core-navigation { DISPLAY: none }
#contentRow > #contentBox { margin-left: 0px; margin-right: 0px; }  

/*Change top SharePoint bar color blue to red*/
#suiteBar > #suiteBarLeft {background-color: red}

What I want is that this Changes are only applied to one page and the rest should use the default SharePoint design.

I am quite lost what I have to do now. Hope I could explain my issue correctly.

  • You want this to apply only on one page or only on root site master page? Feb 20, 2017 at 16:43
  • You should not edit the Out of the box Master, instead download it, create a copy, edit and rename it, and than upload it to Master Page library. And apply it on site, while applying don't check the box "Subsites inherit same master page setting" Feb 20, 2017 at 16:44

Instead of the below code:

// Enumerate through each site and apply branding.
foreach (SPWeb web in site.AllWebs)
     // Activate the publishing feature for all webs.
     web.Features.Add(new Guid("94c94ca6-b32f-4da9-a9e3-1f3d343d7ecb"), true);
     web.MasterUrl = webAppRelativePath + "_catalogs/masterpage/MyCustom.master";
     web.CustomMasterUrl = webAppRelativePath + "_catalogs/masterpage/MyCustom.master";


Use the following:

var rootWeb = site.RootWeb;
rootWeb.Features.Add(new Guid("94c94ca6-b32f-4da9-a9e3-1f3d343d7ecb"), true);

rootWeb.MasterUrl = webAppRelativePath + "_catalogs/masterpage/MyCustom.master";
rootWeb.CustomMasterUrl = webAppRelativePath + "_catalogs/masterpage/MyCustom.master";


This will change only the master page for Root web and not all the subsites within the site collection.


If you only want to apply Master Page on the web for which the feature is activated than following code should help (keep feature web level):

var webOnWhichFeatureActivate = properties.Feature.Parent as SPWeb;

SPWeb rootWeb = webOnWhichFeatureActivate.Site.RootWeb;

// Calculate relative path to site from Web Application root.
string webAppRelativePath = rootWeb.ServerRelativeUrl;
if (!webAppRelativePath.EndsWith("/"))
  webAppRelativePath += "/";

webOnWhichFeatureActivate.MasterUrl = webAppRelativePath + "_catalogs/masterpage/MyCustom.master";
webOnWhichFeatureActivate.CustomMasterUrl = webAppRelativePath + "_catalogs/masterpage/MyCustom.master";

  • It works but only if the scope is set to Site I need the scope to be Web. What do I have to change what is the difference. If the scope is set so Web the master Page is uploaded and I can find it in sharePoint but nothing happens when I activate/deactivate the site feature.

  • I think it shouldn't only affect the root web I think it should affect only where is activated. I am not sure but I think that was the reason why it has to be a sitefeature and not a sitecollection feature

  • Actually AFAIK, the Master Page itself will only host in the root web's Master Page gallery.. only than it will work.. however, you can choose it to only apply on web for the feature it is activated.. I will update the code for the same Feb 21, 2017 at 11:17
  • @socramm check the updated code, the Module for deploying Master page will remain the same, the feature will be WEB level and this code should only change master page for which the feature is activated. Feb 21, 2017 at 11:23

    thanks a lot. For the Deactivation I also copied your code but changed MyCustom.master to settle.master. Is this the correct way of doing it?
