    Hi, I need to page in a RadGridview some result of search query. The RIA query can return from 1 to 62000 items. Like RIA service are limited in the return size (Over 10000 item the RIA clien callback function start to crash with "not found" error) i try to found a way to manually implement page in RIA side.
    For example I can load the fisrt 10000 result and page it with the radpager (that work good). But it is possible to inform the RadPage that 30000 other result are waiting serveur side if needed? Then I could catch an event to call the correct page load function server side. I read that I neet to implement a Domain Data Source for that? Waht about MVVM way of doing this? Do you have some sample with DDS and RadPage over a large database?

    Hi Pierre,

    Please check this online demo. The database in this case is not very large, but the performance would be the same for a bigger database because only the needed data is returned to the client.
    You might want to check the other demos of RadDataPager or the online documentation.

    Hope this will get you started.
