Why does the QueryableDomainServiceCollectionView reload data when submit successfully completed?

[xu]

Hi,

When I using the  QueryableDomainServiceCollectionView to submit changed data,  I find that it always reload the data after the submit succeed. I just wandering why does that need to happen, since the DomainContext will automaticly refresh the data after its SubmitChanges calls.

Hello,

This behavior is by design. The QDSCV needs to load data from the server after the changes were submitted to make sure it is in a consistent state. It does not "listen" for the DomainContext -- it simply uses it to submit a query to the server and when data arrives back it "fills" itself up with the entities returned from the server.

If you want, you can attach to the LoadingData event and cancel it only one time (i.e. with a flag) after you know that this load is caused by submitting changes.

I hope this helps.
