Pass variables between canvas apps

Hi All,


I have 3 embedded canvas apps in my  Model Driven CRM Form. Each canvas app is placed in a separate tab on the CRM Form
Each app has a save button in it to submit the form (EditForm) data.


I want to introduce a validation such that if the user navigates to another tab without saving the data in the app (present in current tab ), he should receive an error notification "There are unsaved changes".


Challenges -


  • Tab is part of CRM Form, hence on click of the tab i need to understand if the canvas app has unsaved changes.How should i communicate between App and Form.
  • Can we share variables between canvas apps so that i can understand the first one is dirty when the user lands in another canvas app without saving.

    Kindly suggest.
