What should I do for my wpf grid to receive and handle data although notifications arrive from a secondary thread.

What should I do for my wpf grid to receive and handle data although notifications arrive from a secondary thread.

you asked a beautiful question I am quite comfortable with. Anyway I use Dapfor grid running my program. This c# code will help you base on your question.

C#

System.Threading.Timer timer = new System.Threading.Timer(state =>
{
Order order = _orders[random.Next(_orders.Count)];
order.Price = random.Next(50, 200) + random.NextDouble();
}, null, 0, 500);

I will suggest you avoid using threads directly. Look into the TPL. How is your data coming? Using signalr? Dispatcher. Invoke should come in handy.
