Loading ASP.net loadable list on demand
I was wondering if anyone knows or comes across any tutorial or how it loads data into a dropdownlist on demand, for example using the telerik rad control where you can first load 10 items into the dropdownlist control and then at the very bottom of the dropdown there is a continuation or loading of the next 10 items, click on it, then the control will load the next 10 items ... etc.

You should be using AJAX control instrumentation - especially the CascadingDropDown Sample . I'm sure you can customize the handler to restrict the return set and expand on demand.
