Write multiple text lines while the page is performing a lengthy task

Question

I am writing a page asp.netthat prints the text as follows:

protected void Page_Load(object sender, EventArgs e)
{
    Response.ClearContent();
    for (int i = 0; i <=100; i++)
    {   
        var isOk = DoSomeTask(i);
        context.Response.Write(string.Format("Step {0}: {1}",i, isOk ? "Success": "Error"));
        Thread.Sleep(4000);
    }
}

I have a problem, the text is displayed only when the page loads successfully. How to render text at runtime?

Answer 1

It is good that I read your question quite early, but did not answer, because I was afraid that I could not give you recommendations on a compressed code sample. You will encounter the same obstacles with both AJAXhandlers ( ashx) and both are pretty similar.
