Use RowDataBound event like following:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
        if(e.Row.Cells[0].Text =="F")
        {
            e.Row.Cells[0].Text = "CF";
        }
        else if (e.Row.Cells[0].Text == "N")
        {
            e.Row.Cells[0].Text = "CN";
        }
}

On button Click Try this..

foreach ( DataRow dr in GridView1.Rows)    
{
    dr["columnname"].Value = "abcd";    
}
