How to highlight a specific row in a datagridview

Question

I am building a form with a datagridview and a button to add items to the datagrid view.  I would like to highlight (and optionally center and not select) the row of the just added item to verify for the user what has changed.  I can't seem to
get it working:
 $dataGridView1.datasource = [System.Collections.ArrayList]@($list)
 foreach ($Row in $dataGridView1.Rows) {
       if ($Row.Name -eq $newitem.name) {
           dataGridView1.Rows[$Row.Index].DefaultCellStyle.BackColor = Yellow
       } else {
           dataGridView1.Rows[$Row.Index].DefaultCellStyle.BackColor = white;
gives me no change.  I suspect the problem is my attempt to reference properties of the Row (e.g. $Row.name), but I don't know.
I would really love a little assistance if anyone is willing.
Thanks.

Hello cascomp,
Currently, I agree with Justin. You can change the cell background color when you add a item.
I tried to accomplish your goal by myself, here is the result. I hope it can give you some ideas about your problem.
If you have any suggestions or ideas, please feel free to tell me.
Best Regards,
Greg Gu
