Set focus on null fields!

Hi,
I have a login form and I have two text boxes in it and the user is required to enter data in the textboxes.If they fail to enter data in any one of the text box and hit the submit button I would like for the cursor to setfocus on the empty text box for the user to enter the data.How would I do this in asp.net.If not would I be able to write Javascript and call the function and where would I call the function.COuld someone expalin how to accomplish this.I do know how to set focus on the first textbox when the page loads up.But I am lost when I am required to setfocus the cursor at the empty text box for user entry?try this:

string strScript = null;
strScript = "<script language=javascript> document.all('TextBox1').focus() </script>";
RegisterStartupScript("focus",strScript);

HI Azam,
I am getting a synatax error. Do I have to declare strScript in my Dim?Also is this a subroutine all by itself or is it part of another subroutine(like page_load)?
Hi,

try to put this code on the Server Side Button Click event.
HI Azam,
I tried your way but I get the error message that says strString is not declared.Also in your code the "TextBox1" would be the ID for the text boxes I have in my project Right?
declare strString as a string variable.

like this:

string strString = "whatever"; // C# syntax

Yes "TextBox1" is the id for the textboxes you have in yr project.
HI Azam,
I am doing this in VB .would the codes be any different if it is VB.
Only syntax.

Here is aC# to VB.NET converter.
HI Azam,
If I did it by your codes would I be able to set focus on the null fields or just the first text box.I am so many error message and that's why I could not see the results.Could you please mail me regarding this?Thanks.
Hi Picky,
Thanks.That is a cool tool!

Set Postback or Session Timeout

Hi All.
I have a page that users enter information in text boxes...and
sometimes it's a lot of information. There are times that these folks
either take their time entering the info or do other things before they
submit the page. Unfortunately, if they do take their time, there are
times where the session times out and they can no longer submit their
information, resulting in an error and pretty peeved users.
What I'm asking for help on is...can, possibly through a timer or
something either reset the session or do a postback? This would be to
cover in case the user would take too much time to submit the
information....it would happen automatically. I do have a popup box
that warns them they are about to time out, but it might not be seen.
So far, I have tried a timer to redirect the page to itself, try to go
through the page_load and try to set the session.timeout, but none of
it looks to work. I did see some __doPostBack and Page.GetPostBackEvent
articles, but didn't see how to put them to use. They get mentioned,
but I don't see how to make them function on my page. I need some way
to try to keep the session alive and not timeout. Sorry if it's
something that's easy that I don't see. I'm still a bit (ok, well very)
new at this I have searched Google high and low and found nothing that
looks to work.
Thanks for any help you can be!!
kurtYou can:
1. Extend the length of the session timeout.
2. Store your information in ViewState instead.

Maybe you can use a (small) iframe that refreshes itself every few minutes,
to keep the session alive but without submitting the entire page
(and losing scroll-position and focus).

Sorry I didn't get back sooner, but I was out for a while. I'm not
sure extending the timeout would work. If I set it to 30 minutes,
they'll probably go 31...and so on. I also wasn't sure that the
viewstate would be usable and last either. But, I did try the iframe
and so far it looks to do exactly as I needed. I also have been trying
it out and I don't look to lose focus from the control I'm currently
using when the iframe refreshes. Thanks for all the input!!
