We have a EditiableRootList bound to a DataGridView. A new row is added and when we hit TAB to go to the next new row, the one we just entered disappears. If we enter an new row and then click on an existing row above it (i.e. Don't hit tab to go to the new next row) then it stays.

Any ideas?

Thanks,
BR

Assuming you are using 2.0, it is possible that your GetIdValue() method isn't returning a unique value for each object as discussed here

Another possibility is that your AddNewCore() override isn't properly adding the new child. Make sure your approach matches the one in the book from Chapter 7.
