I am adding rows dynamically on code behind depending on the Row currently bounded on RowDataBound event. I want that added row to be the same state (Alternate or Normal) of the currently bounded row is this possible?

I'm doing something like this but it doesn't follow what I want. I'm expecting the added row dynamically would be the same as the current row. But it is not.

protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
        GVData data = e.Row.DataItem as GVData;  // not original object just for brevity
        if(data.AddHiddenRow)
        {
            // the row state here should be the same as the current
            GridViewRow tr = new GridViewRow(e.Row.RowIndex +1, e.Row.RowIndex + 1, DataControlRowType.DataRow, e.Row.RowState);
            TableCell newTableCell = new TableCell();
            newTableCell.Style.Add("display", "none");
            tr.Cells.Add(newTableCell);

            ((Table)e.Row.Parent).Rows.Add(tr);
        }
    }
}
