Hello,

I consider moving from datasets in my remoting application to LLBL.

With datasets I could use DataSet.GetChanges method to get a dataset with changed records on a client. This dataset I passed through remoting to an application server, did necessary inserts, updates, deletes, returned refreshed dataset to the client, merged it with the client dataset and commited changes to the client dataset.

Is it possible to do something like this in LLBL? Or what will be the routine using LLBL?

Regards, Vladimir

In LLBLGen Pro you use the entity collection's DirtyEntities property (It's in adapter, as you're using remoting, adapter is highly recommended) to get the entities which are 'dirty'/changed. Then send it to the server and process the collection there. You send the new collection back.

On the client you then use a Context and add the received collection to the context. Then you traverse the original collection and call get on the context to get the object in that context (which is from the server) which represents the same entity.
