Jiteendra Sampathirao · Answer

CascadingDropDown is an ASP.NET AJAX extender that can be attached to an ASP.NET DropDownList control to get automatic population of a set of DropDownList controls. Each time the selection of one the DropDownList controls changes the CascadingDropDown makes a call to a specified web service to retrieve the list of values for the next DropDownList in the set. AutoComplete is an ASP.NET AJAX extender that can be attached to any TextBox control and will associate that control with a popup panel to display words that begin with the prefix typed into the textbox.
