I am a beginner with Telerik ORM and I already used the quick start guide to create a simple silverlight application that fetches and updates database tables.
I didn't find, though, how to create database transactions inside the silverlight control (begin, rollback, commit).
Is there any code example for that?
Thanks,
Alon

Let me shed some light on how you can handle transaction like actions using the client context in Silverlight. First of all the objects you retrieve from the context are disconnected from it. The usual scenario will be to get some objects, modify them a bit and then call the update method on the context. Finally call the SubmitChanges method that will do a service call and update the actual database.
Here it is important to notice that the context will hold the changes you want to be persisted, it will work as a change set. If you want to rollback the changes you can easily create a new context that does not hold any changes. Or even use the old object with the new context, as they are disconnected it will work without problem.
To wrap it up, there is no need for a 'begin transaction', as it would automatically begin. The SubmitChanges method stands for a commit and you can easily rollback the changes when you create a new context.
I hope this helps. Please contact us back if you need further assistance.
