Hi Victor,

This is a probolem with the DataGrid and the best way around this is to use an ArrayList or a collection (as Bonnie pointed out) to keep track of what rows in the underlining data to delete. You delete rows from the DataTable not the DataGrid.

>I noticed that if all the rows I select in the grid have a File Number (which means none of the selected rows will be deleted), this seems to work fine. A messagebox pops up x number of times telling me I can't delete file 'xyz'. However if all (or some) of the rows do not have a File Number this doesn't work correctly. Stepping through the code I see that the first File Number it hits which equals "", gets deleted (dr.Delete). Howevever after that, the If Me.dgFileInfo.IsSelected(i) check is never true again. I have tried various combinations of records selected in the grid and every time once a record has been deleted, the IsSelected check doesn't equal true anymore.
