Progress report using SignalR and IProgress interface

Question

I have a Hub class, which has a long running method, I need to display a progress bar while it\'s working.

I read this article and I think it is possible to use IPro

Answer 1

In your javascript add the following client method

 var appHub = $.connection.appHub;
  $.connection.hub.start();
  appHub.client.progress = function(progresspct) {
     // logic for whatever you want to do.
  };

  appHub.server.getServerTime()
          .done(function (time) {
                alert(time);
           });

Modify your server side code to this -

    public async Task GetServerTime(IProgress prog)
   {
    await Task.Run(() => {
        for (int i = 0; i < 10; i++)
        {
            prog.Report(i * 10);
            // Call to your client side method.
            Clients.Client(Context.ConnectionId).progress(i);
            System.Threading.Thread.Sleep(200);
        }
    });

    return DateTime.Now.ToString();
}
