Edit data in related standalone tables

Discussion created by robert.zargarian@zettate on Oct 31, 2012

I have a file gdb and .mpk file with feature layers. Some feature layers have related tables and those related tables
have related tables and so on. All relations are defined as relation classes in Geodatabase.
I want to build a WPF view to allow user to edit data in feature layers and related tables. Controls in the
WPF view are going to be binded to data from a feature and rows in related tables. So I created ArcGISLocalFeatureLayers
for these standalone tables. If I have SelectionOnly or Snapshot mode on ???Table??? FeatureLayers then all rows are loaded
when layers are initialized and updated. There could be many rows in related tables which make loading off map slow.
There are more than 10 related tables.
What is the best way to read rows in related tables and edit them?
How to deal with this when connected to SDE? Then there are over 500 000 rows in related tables?

Best regards
