test return value after executing NavigateToAsync command

Question

The following code works perfectly. but now I want to test the value returned in a global variable. (this is an inventory system with a multi column checklist page that calls and populates the infopagemodel when I tap an item/line , so that I can change and save the record )

  OnEditCommand = new Command(OnEditCommandAction);
 public async void OnEditCommandAction(object SelectedObj)
         {
             FilterList filterList = SelectedObj as FilterList;
             var navService = PageModelLocator.Resolve<NavigationService>();
             await navService.NavigateToAsync<InfoPageModel>(filterList, false);
             return;
         }

I need to run the following or something like it after returning from InfoPageModel so that I can change the background color of the line that I just saved.

 // global class
 namespace app.Resource
 {
     class Global
     {
         public static bool SaveOK = false;
     }
 }

 //cs code
 // if record saved set SaveOK to True and return from infopage  then check .
 Task task = CheckSaveStatue();
 public static async Task CheckSaveStatue()
 {  
 if Resource.Global.SaveOK then backgroundcolor = ..
 or
 _saveOK  = Resource.Global.SaveOK ;  
 if _saveOK then  backgroundcolor = ..
 }

I tried to trace the code and I cant find where the app go to,

it executes the navService then Return; then it opens the infopageModel then the cursor is no longer visible afterwards

TIA

I'm going to close this post, I'm not happy with the way this app is turning out.

I'm going to try a different project.

Thanks for trying to help.
