Does the DevForce 2010 Verification Engine support one of my verifiers executing code that will cause a request to the server that would use a callback when the server-side call returns?
The purpose for this would be to get a stored procedure to run that can determine the validity of an instance of my entity based on an operation against a bunch of data in the database. It's too much data to bring it all client-side, but I don't want to wait to fail the save on the server to give the user feedback that I could have told them while they were entering the data on the client.
If it's not supported directly, could I implement my own class that holds the results of asynchronous verifiers returned from the server, and then have the callback re-fire the verifier on the associated property and have this new execution of the verifier pick up the results of the previous asynchronous execution to return this time instead of executing the asynchronous method a second time?
Thanks.
