if you can't use javascript and you don't want to use postbacks then I don't think it is possible...

Why you don't want postbacks? If you want to use AJAX control then here is that control ? http://www.asp.net/AJAX/AjaxControlToolkit/Samples/CascadingDropDown/CascadingDropDown.aspx[^] Another alternative is using javascript There is one more method called PageMethods using AJAX search for it that can also help you

Hi, Use JavaScript for that. Please check the JavaScript codes here: http://javascript.internet.com/forms/country-state-drop-down.html http://javascript.internet.com/forms/dynamic-drop-down-list.html Call the function in Attribute Collections, like DropDownList1.Attributes.Add("OnClick",....); Hope this helps.
