How to append options to CascadingDropDown after initially populated v(jamesewelch.com)

submitted by jamesewelch(2275) 1 year, 1 month ago

I needed to add additional dropdown options to a DropDownList web control in use by the Ajax Control Toolkit CascadingDropDown ASP.NET AJAX extender. The CascadingDropDown provided a means to get an automatic population of a set of options called by the web service. needed a way to append an “All” option to the drop down list, but I didn’t want to automatically include “All” as valid option in my Web Service. I wanted to append it on a specific form rather than as part of the data feed.
