Set background color only for the first row in a DataGrid?

Question

I'm trying to change the color only for the first color of a DataGrid in a smartDevice project in c#. I tried to use the "Paint" event but couldn't figure out if it could solve my issue. I'm using Microsoft Visual Studio 2008.

This is a testing code

private void buttonRed_Click(object sender, EventArgs e)
    {
        DataRow row = this.dataSet1.Tables[0].NewRow();
        row[0] = "002";
        row[1] = "E";
        this.dataSet1.Tables[0].Rows.InsertAt(row, 0);
    }
    private void load()
    {

        this.dataSet1.Tables[0].Rows.Add(new object[] { "001", "A" });
        this.dataSet1.Tables[0].Rows.Add(new object[] { "002", "B" });
        this.dataSet1.Tables[0].Rows.Add(new object[] { "001", "C" });
        this.dataSet1.Tables[0].Rows.Add(new object[] { "003", "D" });
    }
    private void buttonGreen_Click(object sender, EventArgs e)
    {
        DataRow row = this.dataSet1.Tables[0].NewRow();
        row[0] = "004";
        row[1] = "F";
        this.dataSet1.Tables[0].Rows.InsertAt(row, 0);
    }

Answer 1

dataGridView1.Rows[0].DefaultCellStyle.BackColor = Color.Azure;

Just do this will work... 0 means the first row.
