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.

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.

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.

I have four dropdownlist boxes Each contains 1,2,3.....7 subitems.
I have filled first dropdown in page_init event by using
Me.ddlPickupNoOfDays1.Items.Add("1") .......Me.ddlPickupNoOfDays1.Items.Add("7") Now I want to fill remaining 3 dropdownlist boxes with same values And I dont want to write the same code in page_init event how can I fill remaining 3 dropdowns using first If someone knows please help
Why u using this long way, why dont you edit items in dropdownlist properties, much easier, you dont have to write any code.
Hope this helps,
