You should be able to just do:

alert(document.activeElement.tabIndex);

The should get you the active control and its tab index.

AFAIK asp.net is a technology for serving HTML pages =)
If you want to know tabindex of current element in HTML, then you should use document.activeElement.tabIndex. this seems to be javascript question, though.
