I'm using VS2005, WinXP, and SQL2005. My application edits a row in a DataGridView, when a button is pressed the DB is updated. This is what I do private void buttonOptShowUpdateDB_Click(object sender, EventArgs e) { try { using(TransactionScope ts = new TransactionScope()) { t_ProductVariantsTableAdapter.Update (LicDBDataSet.T_ProductVariants); // Commit the transaction ts.Complete(); LicDBDataSet.AcceptChanges(); } } catch(Exception ex) { Debug.WriteLine("OptShow DB Update ERROR !!"); Debug.WriteLine(ex.ToString()); } } When the update button is pressed the DB is updated correct, but my DataGridView becomes empty (I.e. no rows visible). The DataGridView is present on a tabbed form, and if I change from the current active tab and back I could see the modified data. Obviously there is a call that is missing but which one???? -- Regards Ole Asbjorn Fadum Scanmar AS
