Populate One Drop Down List From Another
 

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.

Well just populate second dropdown in SelectedIndexChanged event of the first dropdown.

then the page will go back to server to populate the dropdown list
i guess using AJAX is more efficient

Sure it is.
But if she does not know how to populate this way it's going to be harder for her to do it ajax way.
