just trying to make sure I understand you - you say that after the user makes one selection you want to move the cursor to another <select> box?
Jared
BTW, please put your code in [ code] [/ code] tags, it makes it much more readable
Yes I want move a cursor to select a city , for example when I Select Berlin , in combobox2 , stop the cursor in the Berlin City.
For Example:
Combo box 1 : Country : Germany
Combo box 2 : City : Berlin
Combo box 3: State : G1
For More detail :
When I Select Germany in the Country Combo box 1, Show all City of Germany in the Next Combo box (Combo box2) , and when I Select Berlin in the ( Combo box2) , Return the cursor to Hamborg City ??? I have a problem in (combo box2) ?
Thanks for response us.

OK, this is a fairly common problem, moving the cursor is going to have to be done with javascript, there's no way around that. ASP only works on the server, all ASP code is inactive by the time it gets to the user. The code to move a dursor is going to be something like this: - <select name="country" onSelect="this.form.city.focus()">
-
'...
-
</select>
-
<select name="city">
Does this make sense? It's been a while since I've done javascript, but it's something like that.
The other part of the question you seem to be asking is how to limit the results of the second select based on the first choice, so if the user chooses "germany" in the first box, he sees "Berlin, Hamburg, etc" in the second. As I mentioned earlier, the ASP code is inactive by the time it gets to the client's browser, so if you want to use ASP to limit the options in the second select box, you need to submit the form (onSelect="this .form.submit()" ) and then use asp to resend the form with the new data in place in the second box. Does this make sense? If you need help with any part of this task, please ask.
On the other hand, this might slow down the user's experience, and although I've seen plenty of professional sites that use this method, a lot of people use a pure javascript technique wherein all of the possibilities are sent to the user, and after the selection is made a javascript function alters the second select box accordingly. You will have to ask a javascript expert for that method.
There is also one other possibility, the technology "Ajax" was invented to handle exactly this type of issue, and it can communicate back to the server to refresh the list for the second select in real time. This is probably the preferred method nowadays.

Hi Folks,
I am new for this group. I want to clarify one thing what's a basic
difference between Client Side Java Script and Server Side Java
Script. how we can differentiate it. Why we called this kind of script
"Server Side Java Script".
I am in confusion because according to lots of web developer Java
Script is a client side scripting language. We can not say it Server
Side Java Script.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
