I want to save any change that is made to the Datagridview cell value into the database when the save button is clicked. The code that I have only works when I add a new row. For example: if I have first_name Lina and last_name Pual I want to be able to change only the last name

What I have tried:

<pre>    public EmployeeForm()
    {
        this.bindingSource = new BindingSource();

        this.Load += new EventHandler(EmployeeForm_Load);
    }

    private void EmployeeForm_FormClosing(object sender, FormClosingEventArgs e)
    {
        this.connection.Close();
        this.connection.Dispose();
    }     
    private void RetrieveDataFromTheDatabase()
    {
        
        string connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\"Employee.mdb\"";
        this.connection = new OleDbConnection(connectionString);

        this.connection.Open();

        OleDbCommand command = connection.CreateCommand();
        command.CommandText = "Select * From Employee";

        this.adapter = new OleDbDataAdapter();
        this.adapter.SelectCommand = command;

        this.dataset = new DataSet();
        this.adapter.Fill(dataset, "Employee");  
        
        OleDbCommandBuilder commandBuilder = new OleDbCommandBuilder(this.adapter);

        commandBuilder.ConflictOption = ConflictOption.OverwriteChanges;

        commandBuilder.GetInsertCommand();
        commandBuilder.GetDeleteCommand();
        commandBuilder.GetUpdateCommand();

    }        

    private void BindControls()
    {
        this.bindingSource.DataSource = this.dataset.Tables[0];
        this.dgvEmployee.DataSource = this.bindingSource;
    }

    void FileSave_Click(object sender, EventArgs e)
    {
        this.adapter.Update(this.dataset, "Employee");
        
        this.dgvEmployee.EndEdit();
        this.bindingSource.EndEdit();
    }
