sum += Convert.ToInt32(dataGridView1.Rows[i].Cells[1].Value);
}
textBox1.Text = sum.ToString();
int sum1 = 0;
for (int i = 0; i < dataGridView1.Rows.Count; ++i)
{
sum1 += Convert.ToInt32(dataGridView1.Rows[i].Cells[2].Value);

You can set the (entire) Row BackColor or ForeColor directly:

C#

YourRow.DefaultCellStyle.ForeColor = Color.Red;

You can set a particular Cell's colors by:

C#

YourCell.Style.ForeColor = Color.Red;

This thread on StackOverFlow contains a number of valuable examples of working with DataGridView Color styles; I suggest you start by reading this post which shows how to use the DataGridVew's RowPrePaint Event: [^].

And, remember that you can create pre-defined Styles to use:

DataGridViewCellStyle YourRedCellStyle = new DataGridViewCellStyle();
YourRedCellStyle.ForeColor = Color.Red;

// in use:
YourCell.CellStyle = YourRedCellStyle;

Solution 2

try

C#

if (dataGridView1.Rows.Count > 0)
           dataGridView1.Rows[dataGridView1.Rows.Count-1].DefaultCellStyle.BackColor = Color.Red;
