Silverlight 4 Datagrid Sorting -

I am trying to get a silver datagram to sort properly, there is a time chime in, and so much Quickly (sub 1/10 seconds) Here's the scenario:

- Call each 1/5 of each other - Callback to the book, update the properties of up-objective collection in an observational cloth to the existing record- Skip the grid.

I have tried a linq query, PagedCollectionView, and observablecollection.select (), all waaaaaaayay is very slow, and introduces 12+ seconds delay in processing. Anyone else have this experience? Use

PagedCollectionView

, but set it only once, create a view on the application startup and then your Update the object instead of creating new in WCF callback. Then call refresh () on your collection view.
