Marcie,
For web forms you have to set focus with client-side script. You can
emit the script from the server, with routines such as
RegisterStartupScript.
However I never succeeded with this one, because it has to be absolute the
last on a page.
\\\
When this is your textbox (can as well be an ASP box it is the ID that
counts)
<INPUT tabindex="1" id="fieldid" type="text" size="27">
//This should be the last rows in your html aspx file
<script language="JavaScript">
document.all("fieldid").focus();
</script>
</HTML>
///
I hope this helps a little bit?
