Maybe instead of the cell formatting event, try the cell value changed event?

I did up a quick example and it worked. Here's the appropriate snippets...

        public Form1()
        {
            ...
            dataGridView1.CellValueChanged += new DataGridViewCellEventHandler(dataGridView1_CellValueChanged);
        }
 
        ...
 
        void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
        {
            DataGridViewRow row = dataGridView1.Rows[e.RowIndex];
            row.Cells[e.ColumnIndex].Style.BackColor = Color.MediumPurple;
        }

This worked for me... let me know how it works for you :) I'd imagine the access is relatively safe since the row and column index comes from the event, but you may want to put some bounds checking in there anyway.
