Answer 1

That is done using JavaScript/AJAX. You can't do it only with ASP.NET controls.

Answer 2

Take a HTML control and use the "onchange" event of this control. Make a asp code file and write the file's upload code on that file. Now use Ajax and to send request to asp's code file.

When you will select file it will automatically upload by ajax. Because Html control events doesn't use server side.
