C# - Change row color when I select a cell

Question

I have a dataGridView and I want to change the color of the selected row when I click on the cell. I did this with the below code but my problem is when I select the second row then the first row didn't change back to the default style.

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
  dataGridView1.CurrentRow.DefaultCellStyle.BackColor = Color.Maroon;
  dataGridView1.CurrentRow.DefaultCellStyle.ForeColor = Color.White;
}

Could you please help me?

You can store the last colored cell and restore it's coloring when another is activated.

private System.Windows.Forms.DataGridViewRow lastColoredRow = null;
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
    if(lastColoredRow!=null) {
        // Restore the coloring as needed
        lastColoredRow.DefaultCellStyle.BackColor = Color.White;
        lastColoredRow.DefaultCellStyle.ForeColor = Color.Black;
    }
    dataGridView1.CurrentRow.DefaultCellStyle.BackColor = Color.Maroon;
    dataGridView1.CurrentRow.DefaultCellStyle.ForeColor = Color.White;
    lastColoredRow = dataGridView1.CurrentRow;
}
