updating dataset & datagrid, adjusted with tablemapping

[Reinier Domsdorf]

Dear All,

Now that I have a nicly made datagrid, made with the use of the tablemapping, (code from this forum), I am not able to update the data to the
database, I get the following error:

Additional information: Update requires a valid UpdateCommand when passed DataRow collection with modified rows.

I tried to make a commandbuilder-> did not work.
I tried to make a dataset.getchanges (wich is THIS case) ---> did not work.
I tried to make select,update,delete&insert commands manually---> did not work

Can ANYBODY tell me how to update a datagrid-dataset, wich is adjusted with 'tablemapping-code'

Thank you very much, I am getting grey hairs....
