User can use mouse and highlight the whole row in datagrid, 'press' Delete
button (the delete button in keyboard),
And User need to press 'Save & Exit' button, <-- in that button, I will run
daInv.update(dsInv,"mytable)

Finally, got such error.

Agnes,

As far as I know is this not a delete, however a remove. Therefore the row
is removed from the datatable, while a delete just set the rowstate to
delete and removes that with the acceptchanges done in the dataadapter.

In my opinion is the best thing you can do is to disable that behaviour of
that deletekey .
