I am using two WebDropDown controls, in one control during the on_load event all the items will be filled and in the second one depending on the selection from first one, i need to get values from a data source and return it to a service, I can do it from a server side but it will reload the entire page, so i thought i can use Ajax model and do it on the client side. What is the best way i can do this, my return values from the service are Dictionary object from C#, i can change this service to return record set or a table if that is better. Any suggestions are greatly appreciated.

Cascade alternative example answered my question. Appreciate for your quick response.
Hi,
You can refer to our online sample about cascading dropdowns. There using AJAX and client-side API, dropdowns are refreshed without reloading the whole page. The client API function to use is called loadItems(..) :

(The "Cascade Alternative" sample is the same thing, but uses UpdatePanel instead).
For deleting all items on the client side, you can refer to this similar thread:
