    {
        if (dataGridView4.cellvaue <= 35)
        {
            dataGridView4.row_fore_colour = red;
        }

First you must subscribe to DataGrid CellFormatting event like this:

C#

dataGrid1.CellFormatting += new DataGridViewCellFormattingEventHandler(dataGrid1_CellFormatting);

And then in the event handler do something like this:

C#

void dataGrid1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
        {
            if (this.dataGrid1.Rows[e.RowIndex].Cells["cellToCheck"].Value != null)
            {
                if ((int)this.dataGrid1.Rows[e.RowIndex].Cells["cellToCheck"].Value <=35)
                {
                    this.dataGrid1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Red;
                }
                
            }
        }

Hope that helps
