Convert GridviewSummaryItem from Int to time format hh:mm:ss

Hi,

I finally did it.

I delete the line Duracao.FormatString = "{0}";  and add the event GroupSummaryEvaluate with the next code:

private void dgProducaoGeral_GroupSummaryEvaluate(object sender, GroupSummaryEvaluationEventArgs e)
{
            if (e.SummaryItem.Name == "Duração")
            {
                Int32 Segundos=0;
                foreach (GridViewRowInfo row in dgProducaoGeral.ChildRows)
                {
                    Segundos += Int32.Parse(row.Cells["T_H"].Value.ToString());
                }

                Int32 horas = Segundos / 3600;
                Int32 minutos = ((Segundos) - horas * 3600) / 60;
                Int32 segundos = Segundos - (horas * 3600 + minutos * 60);
            
                string result = horas.ToString("D2") + ":" + minutos.ToString("D2") + ":" + segundos.ToString("D2");
                e.FormatString = String.Format("{1}", e.Value, result);
            }

}

This works perfectly

Add an image of the code and the result in the RadGridView and hope this information helps other programmers with the same problem.
