Thank you for writing.
If I understand correctly you are having a WCF which modifies the data in your grid every time a cell changes. In this type of setup perhaps it is indeed a good idea to have your RadGridView
instance in unbound mode.
Please note that even if the grid is data bound and has several thousand entities, it should be able to refresh its view templates without a significant delay. In case, you decide to stay with this kind of setup you can try surrounding the update operation in begin and end update block:
I hope this helps. Should you have further questions please do not hesitate to write back.
