No SummaryDefinitions Output with DataTable?
posted

Hello, i have a SummaryDefinitions put under der Presenter, when i use a IList<MyDATA> as DataSource the SummaryDefinitions works fine. But when the DataSource is a DataTable as DefaultView, there is no SummaryDefinition Output. Any idea? the columns are generated manually, Autogenerate=false.

MyData has a property MA, the DataTable also has a column with MA, where is the problem?

    HI,

     Try setting you AutoGenerate=true and see if your Summary shows up.

     I was able to add a summary definition to my grid without issues.

     Here is my code behind

    private void Window_Loaded(object sender, RoutedEventArgs e)
            {
                NwindDataSet nwind = new NwindDataSet();
                NwindDataSetTableAdapters.OrdersTableAdapter ord = new NwindDataSetTableAdapters.OrdersTableAdapter();
                ord.Fill(nwind.Orders);
                NwindDataSetTableAdapters.Order_DetailsTableAdapter ordd = new NwindDataSetTableAdapters.Order_DetailsTableAdapter();
                ordd.Fill(nwind.Order_Details);

                 xamDataGrid1.DataSource = nwind.Orders.DefaultView;
              //  xamDataGrid1.DataSource = nwind.Order_Details.DefaultView;
                 loadSummary();
            }

            private void loadSummary()
            {
                SummaryDefinition avecost = new SummaryDefinition();
                avecost.SourceFieldName = "UnitPrice";
                avecost.Calculator = SummaryCalculator.Average;
                xamDataGrid1.FieldLayouts[1].SummaryDefinitions.Add(avecost);

                SummaryDefinition avefreight = new SummaryDefinition();
                avefreight.SourceFieldName = "Freight";
                avefreight.Calculator = SummaryCalculator.Average;
                xamDataGrid1.FieldLayouts[0].SummaryDefinitions.Add(avefreight);

            }

    Sincerely,
