Simple, if you're deploying WSP solution packages. Then you can just create, deploy and activate a web application scoped feature using the feature.xml outlined below. Define your custom actions in the CustomActions.xml file.

<?xml version="1.0" encoding="utf-8"?>
<Feature xmlns="http://schemas.microsoft.com/sharepoint/" 
         Title="Feature Title" 
         Description="Feature Description">
        <ElementManifest Location="CustomActions.xml" />

Server side deployments are no longer recommended for new applications. Hence, you should also consider these options for deploying your custom actions:

  • Create and deploy a SharePoint App that registers the custom actions. The app can be deployed to a site collection or globally through the App Catalog site.
  • Use PowerShell scripting to deploy the custom action(s) to all applicable site collections. Leverage the Add-PnPCustomAction cmdlet from SharePoint Patterns and Practices (PnP).

The PnP PowerShell can run remote, works with SharePoint online and on-premises. I recommend this option the most.

  • I don't want to do it with PowerShell. Is It possible through code? Console application or Windows desktop Application. Aug 3, 2017 at 9:51
  • Yes, you can indeed write your own code to do it! That's an equally good approach. Using the CSOM, you'll need to add your actions to the Site.UserCustomActions collection. For example with c# as demonstrated in this article: andrewwburns.com/2013/12/01/… Aug 3, 2017 at 10:31
  • Yes, Exactly i am doing like this only. But I am not able to add it on newly created Site Collection. I can add the custom action on sub-sites if I added the custom action on site collection level. In the Same way I want this to happen for Site Collection. Aug 3, 2017 at 12:50
