>>Hi,
>>
>>I am starting to work on using Local Storage for my ASP.NET MVC/Web API application.
>>
>>The application allows a user when in the office to select the run sheet (list of packages to be delivered) and then a copy of all the data for that run sheet gets stored in the local storage of the browser. The user then delivers all the packages, recording the deliveries in local storage and upon returning to the office all the deliveries are transferred from local storage to the database on the server. Or at least that is how it is supposed to work. :)

        public ActionResult Index(Guid id)

>Not familiar with the .saveLocal() method. I just save directly to a key:

localStorage['theData'] = JSON.stringify(vm.runSheetDetails); // Store
>vm.runSheetDetails = JSON.parse(localStorage['theData']); // Retrieve

Don't know if that would work for you. You could look in the Browser debugger to discover the key that was used by 'runsheetdetailsDataService.saveLocal(serialized)'

My saveLocal() basically does the same thing, saving to a key. But that's not the problem, the problem is how do I tell the page/view/controller/model to pull the data from the local storage not from the database? Do I need to detect in my view that we are offline and then load another page which ignores the MVC model and just loads it from local storage? Or is there another way?
