If the cell of column "Prezzo Forzato" is higher than 0 I set to 0 the cell of column "Prezzo Listino", in this esample, the first row have a "Prezzo Forzato" = € 4,00 and i set the cell "Prezzo Listino" = €0,00.
I do not know how to do this.
I tried to do this dettaglio_RowLoaded is the grid of data template:

private void dettaglio_RowLoaded(object sender, RowLoadedEventArgs e)

{

if (e.DataElement != null)

{

var dettaglio = e.DataElement as AGECOPCOMDET;

var row = e.Row as

GridViewRow;

           if (row != null)

         {

if (dettaglio.AgeCopComDetPreFor != 0)

{

row.GetCellFromPropertyName("AgeCopComDetImpLis").Value = 0;

}

But is don't work,

I get no errors, but I get a white screen as in fig.2

If comment the line:
row.GetCellFromPropertyName("AgeCopComDetImpLis").Value = 0;
is work, but don't change the value of cell "Prezzo Listino" to 0.
How do I change the price of the cell "Prezzo Listino" when the cell "Prezzo Forzato" is > 0 ?

Tnks
Aurelio
