Answer 1

Have a look at the AjaxFileUpload control in the Asp.Net Ajax control toolkit. It supports async file uploading and will display a progress bar in browsers that supports the HTML5 File API (not IE9 unfortunately).

Anyway, instead of me repeating what's on the page, go have a look yourself.

Edit: Oops, just realized that you wrote you are using .Net 2.0. I think the Ajax control toolkit needs at least .Net 3.5 nowadays.

Answer 2

I think you want this kind of stuff.. if you want to add this on web site.

then you need to:

1) add reference(System.Windows.Forms) in solution

2)Then add line:

        System.Windows.Forms.ProgressBar progressbar1;
        progressBar1.Minimum = 0;
        progressBar1.Maximum = 2000;
        for (int i = 0; i < progressBar1.Maximum; i++)
        {
            progressBar1.Value = i;
        }
