Question

Hi,

I'm currently evaluating the Telerik Reporting tool for our project. I've discovered that the Reporting tool uses a worker thread to fetch the data. At the moment we use a static class that opens 1 Session to the DB for the whole application. Of course this Session is not available in the worker thread. I've tried the following

using(var Session session = Session.Open(Domain))
{
    // Getting data here
}

but that only posponed the next exception saying 'the connection is closed'. Could you give me a few pointers?

Regards

I see two options:

You must ensure working Session is activated in the worker thread. I'm almost sure there should be some entry points for this.
Or you can try to disable this feature of Telerik Reporting. Normally any multithreading stuff can be turned off.

Also, usage of current Session is fully optional in v4.4 (this will help, if this is the root of this issue) - shortly we'll show its beta (actually, the only TODO we must finish to release it is documentation). Beta already passes the same set of tests, so it's as stable as v4.3; but since there lots of API changes, we need to gather some comments before final release. A part of these changes (namespace renames and fixes of references - there are just 3 assemblies you must reference) can be applied via Upgrade Tool; for almost everything else we left existing API intact, but old-style calls are marked as [Obsolete], so migration shouldn't be complex as well. And certainly, you won't need to do anything with the data.
