Thanks Eyup for your response to my query. However, I can see in the below mentioned live demo RadDropdownList is rendered when navigated to the next page too though it is a server side control, which is precisely what I am looking for. Can you please let me know how, not sure if I am missing anything here?
Also, I have set the page size currently to 10 and if I need to achieve RadDropDownList rendering for all the items in all the pages, as you mentioned, how do I manually set its PageSize on server-side?
Can you please provide me with a sample code? Very much appreciate your response.
