Reload Form on reload/refresh of subgrid in Dynamics 365 CRM Unified Interface

I have a scenario where in Orders Form there is a Invoice Schedule Sub-grid. I need to Refresh/Reload the Main Form when the Invoice Schedule Sub-grid is reloaded on Deactivating a particular record in the Sub-grid.

P.S: This scenario is for Dynamics 365 CRM Unified Interface (UCI). I have tried all the three Sub-grid events but does not help in this scenario.

You have to attach a custom event handler to deal this. Read more

var globalFormContext;

function myFormOnload(executionContext) {
  globalFormContext = executionContext.getFormContext(); 

  addSubgridEventListener();
} 

function addSubgridEventListener(){
  var gridContext = globalFormContext.getControl("<your_subgrid_name>");
  //ensure that the subgrid is ready…if not wait and call this function again
  if (gridContext == null){
     setTimeout(function () { addSubgridEventListener(); }, 500);
     return;
  }
  //bind the event listener when the subgrid is ready
  gridContext.addOnLoad(subgridEventListener);

}

function subgridEventListener(context){
  globalFormContext.data.refresh(false);
}
