I have a form where users will input phone numbers. The way it is set up is with three text boxes. First for phone prefix( 314) then second for the middle number (546) and finally third for last four digits (4563). What i am being asked to do is the cursor need to jump to second text box as soon as user inputs 3 digits on the first text box. and so on. Is there a way to accomplish this. Please help!!
Thank you in advance.

You can but you need to be pretty carefull about it.
You need to watch the keypress events for the textboxes (javascript event)
Then you have to watch to see if:
A) the maximum allowed characters are already in the box (for the first box it would be 3)
B) that the key being pressed is a character key and not a control key (like arrow keys, backspace, delete, etc, etc) so that you don't keep jumping to another textbox when someone presses the arrow key.
Then if the end is reached, set focus to your next control.
The folks over in the javascript section might be able to explain it a bit better.
Thanks ,
This means that i will have to use AJAX for this. I know how to do this in classic asp but i am new to AJAX so way confused . Isnt there any other simple solution ??

Well, you don't HAVE to use ajax for this. I don't think you need to have it keep coming back to the server for anything?
can you provide me with example on how can it be done? please

Same thing. ASP.NET still just makes a regular HTML form.
And you're going to be doing this with javascript anyway.

Yes, that's right. When the server-side code gets to the browser it's been translated/converted into client-side HTML markup. View source in your browser and you'll see.

I'm trying to do something very simple...but I can't figure it out
I have an <asp:button runat="server"> in the test version of my app that is
essentially a backdoor for changing the class of user inside the application
on the fly....it has a textbox next to it
you can type 1, 2, 3, 4 etc.. in the text box and when you click the button

Hi,
I need to build an editable Datagrid with add & delete buttons on each
row using javascript.
DataGrid need not be pre-populated with values.
To make the thing complicated, one of the column need to be a date
picker field.
I know things will be easier with ASPX datagrid.

Does anyone know why placing the cursor/focus in a textfield in IE would cause the window.onblur event handler to be called? This seems very odd since the window still has focus....
Is there a way to prevent window.onblur form being called when a textfield in the same window gets focus or to test if the currently focused element is a textfield in window.onblur?
I am testing on IE 6 on WinXP.
Thanks,
Erik

I'm not that great at reading javascripts.
Instead of doing nothing I'd like to return a Tab-character, if Enter
occurs:
<script language="javascript" type="text/javascript" >
//disable enter-key
function kH(e) {
var pK = e ? e.which : window.event.keyCode;
return pK != 13;

Hello guys. I was wondering how you make an event happen when the user presses a key. I have seen code used for this but I don't understand how it works.
Here is the code in a sample I found:
import java.awt.*;
import java.awt.event.*;
public class KeyPress extends Frame{
Label label;
TextField txtField;
public static void main(String args) {
KeyPress k = new KeyPress();
