Hi,
I have 2 drop down lists, in which the selection value of the 1st drop down list will determine the content of the second drop down list.
Is that I need to use javascript function to achieve this? If yes, how should I code the javascript and how should I call the javascript from within Page_Load, can someone please kindly show me an example?
Tour advice is much appreciated. Thanks.

Do you know how to populate one combo?
If you don't i suggest that you read some tutorials before.

Ya of course I knew about populating one combo. My question here is how to populate the SECOND drop down list upon changes of selected value in the FIRST drop down list.

i guess using AJAX is more efficient
programming is an art ,only for those who can understand it.

then the page will go back to server to populate the dropdown list
i guess using AJAX is more efficient
But if she does not know how to populate this way it's going to be harder for her to do it ajax way.
