hi there,

i'm having a problem and don't understand why, maybe you guys can help me.

i have an businesslist, binding to a datagridview, until here works fine.
but when i try to delete a record, i get the following error:
Invalid for root objects - use Delete instead

it's strange because, i didn't define the object has child, and it tries to execute the deleteChild method.

thanks in advance.

Hi,

Objects contained within a BusinessList are by definition children. The BusinessBase objects in the list must call MarkAsChild, usually in the constructor, and you won't get that exception.
