Hi;
How can I getting the real primary key value after SaveChanges. I’m using custom ID generater.
Please give me some example code.
This following code running properly, but I'm not sure is the best way.
 
private EntityList<HT_HESAPPLANI> mHPDetay ;
private int HPID;
 
aHESAPPLANI = HT_HESAPPLANI.Create(mPersMgr, "", "");
mHPDetay = new EntityList<HT_HESAPPLANI>();
mHPDetay.Add(aHESAPPLANI);
mHPDetayBS.DataSource = mHPDetay;
 
mPersMgr.SaveChanges(mHPDetay);
HPID = mHPDetay[0].ROWID;
PrimaryKey HpPK = new PrimaryKey(typeof(HT_VHESAPPLANI), HPID);
HT_VHESAPPLANI pEntityHP = (HT_VHESAPPLANI)mPersMgr.GetEntity(HpPK, QueryStrategy.DataSourceOnly);
 
 
Best Regards

Erturk.
 
The default behavior of SaveChanges is to return the updated entity to the client cache, so there is no need to query the database.  Just access your updated entit y.  It's primary Id will be updated.  However, this will not work if you use the ExcludeFromPostSaveRefetch SaveOption.
 
If you want to convert your temporary id to a real permanent id before you do the save, use the ForceIdFixup method of the PersistenceManager,
