  Maybe you can try for a temporary fix for your project meanwhile. Since you said that you are indeed able to delete the records from DB. Now what you got to do is somehow refresh the contents of the datagrid. On taking a wild guess by just dynamically refreshing the page or any other way of updating the grids contents could probably do the trick.

  I had the same problem, and Jeff Handley confirmed that this is indeed a bug in the DomainDataSource control.  The best workaround that I could come up with is to detach the record from the DomainDataSource, which will immediately remove it from your dataset and datagrid, and then just create a new datacontext to perform the actual delete.  Something like this...

  ddsExistingRecords.DomainContext.Entities.GetEntityList<[entity type]>().Detach(deleteRecord);
  
  [domain context] oData = new [domain context]();
  oData.[entity type].Attach(deleteRecord);
  oData.[entity type].Remove(deleteRecord);
  oData.SubmitChanges();
  

  (Replace everything in the square braces with your project's types.)

  What version of Silverlight / Visual Studio are you using?  Also, please include the error code.
