Hi,   that helped me also alot. But I have one further question on that: How can I access the MasterRow/Item of the current Details InsertionRow? I need that to set the Relation manually:         private void DetailConfiguration_InitializingInsertionRow(object sender, InitializingInsertionRowEventArgs ...

I have a Data Table in a DataSet bound to my DataGrid. Updates are working fine. But the insertion row disables input on all columnes except the one with ComboBox CellEditor. The other columns are just plain string and numbers with no cell editor. I can modify cells in these columns except the insertion row. What's going on?

Does version 3.0 supports ObservableCollection for editing and adding new record? Or we still have to use IBindingList Interface. If yes can you guide me with any examples. Thanks  Atul   

  I am not able to find any example where we can add,edit data based on ObservableCollection. Can we do that? or are we stuck with bindableList. Secondly if the above data is exposed in combobox do how exactly we use xcdg:CellEditorBinding Thanks
