How to load content through Ajax in Angular Tab

31 Aug 20266 minutes to read

The Tab component supports loading external content through Syncfusion’s Ajax utility using HTTP POST requests. This approach is useful when sending data to the server or when the content requires authentication parameters.

Steps

  1. Import the Ajax module from ej2-base:

    import { Ajax } from '@syncfusion/ej2-base';
  2. Create a new Ajax instance with the target URL and configure it for POST.
  3. In the Success event, assign the response data to the Tab’s items[i].content.
  4. Initialize the Tab (or call refresh()) once the response is received.

Method: By default the Syncfusion Ajax helper issues POST requests. Pass { type: 'GET' } to override.
Errors: Handle failures via Ajax failure callbacks or wrap the call in a Promise; see Troubleshooting below.
