ASP, AJAX and postback on dropdowns.

[FabriceB]

Hi, I need some help on how to do postback on dropdowns which were populated by a DB through the use of AJAX.

the code I used is the one I had posted in the following thread:
http://codingforums.com/showthread.php?t=187836

Can anyone help me on how to approach this? when I google asp ajax and postback so far i only seem to fall on .net results which is not what i need...

Thanks in advance for any assistance!

do you mean chained dropdowns or just 1 drop down per query?

Hi,
Thanks for replying so quickly,
If chained is the same as cascading then yes.
They are interrelated.

I use a stored procedure which takes each newly selected parameter to obain the following list.

i.e.: dept is selected, the sp will fetch all managers... managers are selected, all team leaders are obtained by the sp... etc..

i just released one.

you can use php if its installed on the server, but its pretty straight forward and can be converted to asp no problems.

Thank you for the link.

I clearly see I still have a lot to learn about all this since I don't really see in your code how you handle the postback.

the php just gets the data from the database, that code just checks for the url variable and if it exists use the variable, like a query string. all the postback stuff is in the jquery on the index page.

so you mean the fact that you're using method="post" ?
