No overload for method 'BindGrid' takes '0' arguments

hi experts,

I created a bindGrid() like this  
private void BindGrid(string Id)================> I passed it a string id
            {

                  string ConnectionString = ConfigurationSettings.AppSettings["connectLocal"];
                  SqlConnection  myConnection = new SqlConnection(ConnectionString);

                  SqlCommand myCommand = new SqlCommand("sp_DestinationElements", myConnection);
                  myCommand.CommandType = CommandType.StoredProcedure;
                  SqlParameter param = new SqlParameter( "@employerId", SqlDbType.VarChar, 50);
                  
                  param.Value = Id;
                  myCommand.Parameters.Add(param);

                  try
                  {
                        myConnection.Open();
                        dgCompensation.DataSource = myCommand.ExecuteReader(CommandBehavior.CloseConnection);
                        dgCompensation.DataBind();
                  }
                  catch
                        (SqlException Sqlexc)
                  {
                        lblStatus.Text = "Error while Generating Data. Error is " + Sqlexc.ToString();
                  }
            }
            #endregion


When It comes to creating the edit control
      public void dgCompensation_Edit (object sender, DataGridCommandEventArgs e)
            {
                  dgCompensation.EditItemIndex = e.Item.ItemIndex;
                  BindGrid();      
            }

What can i pass here BindGrid() apart from BindGrid(null);

THANKS AGAIN GUYS
