Hello friends.
I am designing a system where the requirement is as follows:
I have to send a large file (10mb +) to asp.net through AJAX. The file will be sorted in the server and it will take time. I have to notify the client the status of the sorting accurately.Suppose I am sorting 100 sets of data from the file. In this case I have to notify the client after sorting of each set is finished.
How can I do it?
Any suggestion with link to implementation would be highly appreciated.

You can achieve it through tow way

- On client side, run a timer that will check periodically if any notification available from DB and for notification update the database.
- Second is, use SignalR through this register a method on client side and on server side once you done your sorting then call this method. That method will notify automatically on client side through Jsrcipt.
