Filter regrabs data

[Baatezu]

Does the grid need to re-grab the data [run NeedDataSource] when applying a filter?

I'm dealing with a lot of data and I'd much prefer to not have to re-grab/transfer that data.
I'd be interested in being able to apply a filter without having to re-grab the data.

This also applies to paging. :)

I'm probably missing something stupid, happened last time. :-P

Hello Baatezu,

Yes, RadGrid need to retrieve the data once again as the data is not stored by RadGrid  and this operations are performed against the data. You can use LinqDataSource/EntityDataSource in order to perform this operations on your DB server. Bellow links shows tips and tricks on performance:
