hi, I don't know where your database located. If your db is in server machine using SQl server, you must provide an accessing permission in Enterprise Manager with Security item. It seems to be a solution.

Thanks a lot, but i'd like to put this filters rows in dataset again, only filters rows. :^) thanks again!

Thanks for help me! this code was great, it helped a lot. if (e.KeyCode == Keys.Enter) e.Handled = true; Thanks again!! :-D

Thanks dude! i didn't know that DataGridView has this movement by "Enter" instead of "Tab", without need to use code. it was a good tip. Thank you a lot.

thanks dude!! i'll try it "Filter on the DataGrid"!! if i find out anything else i´ll call you again!!! cya!
