Set your cell datagridview color

DataSet dataSetMachine = new DataSet();
            dataSetMachine = new MachineSystem().GetDataMachineStatusperCompanyPlantSectionLine(3100,3110,"A","");
            DataTable tabelMachine= new DataTable();
            tabelMachine = dataSetMachine.Tables[0];

            foreach (DataRow drMachine in tabelMachine.Rows)
            {
                string machineId = drMachine["MachineId"].ToString();
                string status = drMachine["Status"].ToString();
                int sts = Convert.ToInt32(status);
                DataGridViewCell cell = repeaterMachineDasboard.Rows[e.RowIndex].Cells[e.ColumnIndex];

                if ((string)cell.Value == machineId && sts == 4) // mesin bagus
                {
                    //e.CellStyle.BackColor = Color.Red;
                    repeaterMachineDasboard.Rows[e.RowIndex].Cells[e.ColumnIndex].Style.BackColor = Color.LightGreen;
                }
                else if ((string)cell.Value == machineId && sts == 3) // mesin sedang diperbaiki
                {
                    //e.CellStyle.BackColor = Color.Red;
                    repeaterMachineDasboard.Rows[e.RowIndex].Cells[e.ColumnIndex].Style.BackColor = Color.Orange;
                }
                else if ((string)cell.Value == machineId && sts == 2) // mesin baru diketahui rusak
                {
                    //e.CellStyle.BackColor = Color.Red;
                    repeaterMachineDasboard.Rows[e.RowIndex].Cells[e.ColumnIndex].Style.BackColor = Color.Yellow;
                }
                else if ((string)cell.Value == machineId && sts == 1) // mesin bermasalah atau rusak
                {
                    //e.CellStyle.BackColor = Color.Red;
                    repeaterMachineDasboard.Rows[e.RowIndex].Cells[e.ColumnIndex].Style.BackColor = Color.Red;
                }

Solve combobox return object

Selama ini selected value yang aku gunakan di combobox selalu return object, dan hal itu ternyata disebabkan oleh menempatan display member dan value member setelah datasource,
jadi seharusnya  set display member, value member baru kemudian datasource.

   public MyOtherClass OtherClass;
}

class MyOtherClass

   public int Number;
}

This code help me....

private void dgv_CellFormatting( object sender, DataGridViewCellFormattingEventArgs e )
{
   MyClass data = dgv.Rows[ e.RowIndex ].DataBoundItem as MyClass;

   dgv.Rows[ e.RowIndex ].Cells[ "colName" ].Value = data.OtherClass.Name;
   dgv.Rows[ e.RowIndex ].Cells[ "colNumber" ].Value = data.OtherClass.Number;
}
