Changed datagridview cell backgroung color

I try: dataGridView.Rows[0].Cells[4].Style.BackColor = Color.AliceBlue; and it works fine but in case i am add item to my datagridview i don't know which Row number i am working with.

this is how i am adding items to my datagridview:

    public void addToDataGridView()
    {
        dataGridView.Rows.Add( "test1", fileName, fileSize, DateTime.Now, "myStatus");
    }

There are more than one way to do this:

  1. If you need to change color for entire column:

    DGV.Columns[ColumnIndexToColor].DefaultCellStyle.ForeColor = Color.AliceBlue;

  2. If you need to change color based on some condition and your DGV is bound, you can use DataBindingComplete event

    private void DGV_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
  if(DGV.Rows.Count>0 && DGV.Columns.Count>0)
  {
    foreach (DataGridViewRow r in DGV.Rows)
    {
      if(condition)
      {
        DataGridViewCheckBoxCell cell = r.Cells[ColumnIndexToColor];
        cell.Style.BackColor = Color.AliceBlue;
      }
    }
  }
}

  3. If you need to change color based on some condition and your DGV is not bound: when you add row to DGV as in answer by @Chris

if you are using dataGridView.Rows.Add(), you are adding row to end of dgw => its index will be dataGridView.Rows.Count - 1

EDIT:
Solution of Chris is much better than using dataGridView.Rows.Count - 1

You can choose other solution - you create DataGridViewRow in which you can set style etc. and then simply add it to dgw.

The dataGridView.Rows.Add method gives you the index of the added row.

public void addToDataGridView()
{
    int index = dataGridView.Rows.Add("test1", fileName, fileSize, DateTime.Now, "myStatus");
    dataGridView.Rows(index).Cells(4).Style.BackColor = Color.AliceBlue;
}
