Delegate controls in the SharePoint Add-in model

Summary

The approach you take to implement delegate controls in your code is different in the new SharePoint Add-in model than it was with Full Trust Code. In a typical Full Trust Code (FTC) / Farm Solution scenario, delegate controls were built as user controls or web controls, registered with features, and deployed via SharePoint Solutions.

In an SharePoint Add-in model scenario, JavaScript is embedded in SharePoint pages to implement the same functionality as delegate controls.

High Level Guidelines

As a rule of a thumb, we would like to provide the following high level guidelines for creating delegate controls in the new SharePoint Add-in model.

  • There is no direct delegate control replacement in the SharePoint Add-in model.
  • Use embedded JavaScript to implement the same functionality as delegate controls from an end-user's perspective.
  • Use the SharePoint JavaScript Client Side Object Model (JSOM), and/or the SharePoint/Office365 REST APIs to interact with SharePoint data and services.

See the User controls and web controls (SharePoint Add-in Model Recipe) to learn how to embed JavaScript to all SharePoint pages with custom user actions and how to embed JavaScript directly into page layouts and master pages.
