Edit Saved items from the Database.

Question

Good afternoon,

My question is that How do I go about editing saved items from a Database to an application.

I am already able to save to a database, however how can you implement that when a data is changed it is also changed back to the database.

For example - FirstName = David
Later on you can then decide to change the same First name to - Sam.

Any help will be appreciated.

Regards.

Here is the code I have tried and does not work .If you could point me in the right direction that will be appreciated. private void UpdateDatabase_Clock (object sender, EventArgs e) { DialogResults update; update = MessageBox.Show ("Are you sure you want to update this record" "Delete Record" , MessageBoxButtons.OKCancel); if (update == System.Windows.Forms.DialogResults.OK) { Try { tbl_AppointmentsTableAdapter.update(this.datasetnumber1.TBL_Appointments); tbl_EngineerTableAdapter.Update (this.datasetNumber1.TBL_Engineers); _selectedAppointmentRow = null; } catch (Exception ex) { MessageBox.Show("Unable to delete the record due to the following error; " + ex.Message); } } }

Just use the update command and update the column value for all - without any condition for single row- use where condition on the basis of primary key column Note:- Don't try to update the value of primary key column update tablename set FirstName = Sam where roll_no='101'
