I have this scenario where I am doing translations using toggle button on different modules. The Problem is the code for toggle is written in app.component.ts and I however tried to get the language value in child components but the functionality is only working on page refresh and not on standalone.

Meaning, when i come to home page and switch toggle from En to Fr, it doesnot work but when i goto another link in navigation, the translation works. In short, i need to refresh my child component UI whenever user changes the toggle in parent component.

  • I have this scenario where child component is not loaded/refreshed again when a change happens in parent component. Means I am on a child component view and do an event on a the page header(which is part of parent component), here no constructor of child component is getting invoked .How can we use changeDetection strategy for such a child component.

  • How you notify your child component events or subscribe? Commented Aug 29, 2018 at 20:08
  • I am subscribing using subject and observables like mentioned in :jasonwatmore.com/post/2016/12/01/…. I am able to listen to the event from app but I need to invoke a service call from the listening component and re-populate my dropdowns once theres is an event from app(like hitting a togglebar). Right now the communication is happening but I don't know how to subscribe to service calls and refresh the dropdown in listening component on the click of event. Commented Aug 30, 2018 at 18:43
  • Both these components have their own modules. But app component is the primary one since its loading the other components in application using router-link. Commented Aug 30, 2018 at 19:00
