Single Calculation Header in WPF Pivot Grid

By default, the pivot grid does not show the calculation headers when there is only one PivotCalculation. To show the calculation headers even when there is only one PivotCalculation, use the ShowSingleCalculationHeader property of pivot grid control.

Refer to the following code sample.

c#

public partial class MainWindow: Window {
    PivotGridControl pivotGrid = new PivotGridControl();
    public MainWindow() {
        InitializeComponent();
        grid1.Children.Add(pivotGrid);
        pivotGrid.ItemSource = ProductSales.GetSalesData();
        PivotItem m_PivotItem = new PivotItem() {
            FieldHeader = "Product", FieldMappingName = "Product", TotalHeader = "Total"
        };
        PivotItem m_PivotItem1 = new PivotItem() {
            FieldHeader = "Date", FieldMappingName = "Date", TotalHeader = "Total"
        };
        PivotItem n_PivotItem = new PivotItem() {
            FieldHeader = "Country", FieldMappingName = "Country", TotalHeader = "Total"
        };
        PivotItem n_PivotItem1 = new PivotItem() {
            FieldHeader = "State", FieldMappingName = "State", TotalHeader = "Total"
        };
        // Adding PivotItem to PivotRows
        pivotGrid.PivotRows.Add(m_PivotItem);
        pivotGrid.PivotRows.Add(m_PivotItem1);
        // Adding PivotItem to PivotColumns
        pivotGrid.PivotColumns.Add(n_PivotItem);
        pivotGrid.PivotColumns.Add(n_PivotItem1);
        PivotComputationInfo m_PivotComputationInfo = new PivotComputationInfo() {
            CalculationName = "Amount", FieldName = "Amount", Format = "C", SummaryType = SummaryType.DoubleTotalSum
        };
        PivotComputationInfo m_PivotComputationInfo1 = new PivotComputationInfo() {
            CalculationName = "Quantity", FieldName = "Quantity", SummaryType = SummaryType.Count
        };
        pivotGrid.PivotCalculations.Add(m_PivotComputationInfo);
        pivotGrid.PivotCalculations.Add(m_PivotComputationInfo1);

        pivotGrid.PivotEngine.ShowSingleCalculationHeader = true;
    }
}
