Show message in empty cells in GridView

By That code i am getting all the cells colored
I just need the empty one.. Can someone notice where’s my fault (Sorry I’m new to C#)

    private void simpleButton1_Click(object sender, System.EventArgs e)
    {

        string[] msg = new string[60];
        string[] error = new string[400];
        for (int i = 0; i < gridView3.RowCount ; i++)
        {
            System.Data.DataRow Rows = gridView3.GetDataRow(i);
            string cellvalue = Rows[0].ToString();
            if (cellvalue == "")
            {
                msg[0] = "Missing 'First Name'";
                error[i] = msg[0] + " - ";  
                gridView3.CustomDrawCell += new RowCellCustomDrawEventHandler(gridView3_CustomDrawCell);

            }
        }
    }
    private void gridView3_CustomDrawCell_1(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
    {
        e.Style.BackColor = Color.LightSteelBlue;
    }

By the way this grid was imported from Excel

You need to register grid event only once, not in the loop.
For cell coloring use RowCellStyle event.
