I am creating a parent child relationship between to entities (entity 1 as parent and entity 2 as child).

I want to call save of just the parent and the child is saved too.

Now the problem is I want to add few rows in child, update few and delete few ...

Update and Add works fine, but when i do a datarow.delete for child and try to save the parent it throws a "Deleted row information cannot be accessed through the row" exception.

The add and update works as expected..the delete doesnt... has anyone faced this problem?

Thanks,
Amruta
