DataGridView: Change the color of edited rows

[RSH]

I am working with the DataGridView control in a WinForm. I have written the
code to change the background color of a cell after it is edited. I also
change the color of the row (a different color) which allows users to see
what cells and which rows have been edited.

The problem is that whenever the user sorts the datagidview I lose the
coloration...ho w can I go about making sure that the cells remained colored?

private void dataGridView1_C ellValueChanged (object sender,
DataGridViewCel lEventArgs e)

{

for (int i = 0; i < dataGridView1.R ows[e.RowIndex].Cells.Count; i++)

{

if (dataGridView1. Rows[e.RowIndex].Cells[i].Style.BackColo r !=
Color.Moccasin)

{

dataGridView1.R ows[e.RowIndex].Cells[i].Style.BackColo r =
Color.Beige;

}

}

dataGridView1.R ows[e.RowIndex].Cells[e.ColumnIndex].Style.BackColo r =
Color.Moccasin;

}

Thanks,

Ron
