More details as listed below.

I am getting the error "cannot convert from infragistics.web.ui.gridcontrols.summaryrowsetting to string". Column is defined as integer, not sure why I am getting this error.

ColumnSummaryInfo BNCartonsSummary1 = new ColumnSummaryInfo();

BNCartonsSummary1.ColumnKey = "DDCARG";

BNCartonsSummary1.Summaries.Add(SummaryType.Sum);

wbgdata1.Behaviors.SummaryRow.ColumnSummaries.Add(BNCartonsSummary1);

Columns are added manually as listed below:
tblShipment = new DataTable("Shipment");
tblShipment.Columns.Add(new DataColumn("Cartons", typeof(int)));

tc = wbgdata1.Columns["DDCARG"] as TemplateDataField;

if (tc == null)

{
tc = new TemplateDataField();

tc.Key = "DDCARG";

tc.ItemTemplate = new PlaceHolderTemplate();

this.wbgdata1.Columns.Add(tc);

}

Please help.

Thanks.
