On Demand Paging

[Rik]

Hi,

lately I've been having performance issues as we're working with large dataset (over 3 million in some cases).

I was wondering if there's a way I could use the RadGridView with the RadDataPager to load data using the "on demand" approach. Can I change it to execute the query but download only the records of the current page instead of downloading everything the query returns? If it is, then would the GridView also populate all the filters based on the unique items on not just the current page but all the data from the query?

Thank you,
Rick

Hi Rik,

When we release our new control called RadDomainDataSource, you will be able to bind RadGridView and RadDataPager to it and everything will be done on the server -- paging, filtering, sorting. We hope to release it with 2010 Q3 SP1. The distinct values for the filters will always be taken directly from the server with the help of a secondary RadDomainDataSource.

Currently, we have an example with Microsoft's DomainDataSource, but it has some coding involved.

I hope this helps.

All the best,
