The issue may manifest if aggregate descriptions are added on the pivot`s column axis and if their member does not return data.

I came across an exception when trying to use the Report Filter area with data that contains blank (DBNull) values.  It looks like the control tries to build a distinct list of values to show in the filter's drop-down, but throws an exception if one of the values is blank.  I attached a ZIP file with a Visual Studio project that demonstrates the issue, and included a Word file to describe how to reproduce the error.  

Any assistance is greatly appreciated.  Thank you.

The group description now has AutoShowSubTotals property determining whether subtotals will be generated for the description:

this.radPivotGrid1.RowGroupDescriptions.Add(new DateTimeGroupDescription
{
    PropertyName = "OrderDate",
    Step = DateTimeStep.Quarter,
    GroupComparer = new GroupNameComparer(),
    AutoShowSubTotals = false

The new API would allow some of the default functions to be removed and custom aggregate functions to be added. At the moment the dialog can be modified like this:

Public Class MyAggregateOptionsDialog
    Inherits AggregateOptionsDialog

    Private availableAggregateFunctions As IList(Of AggregateFunction) = New List(Of AggregateFunction)() From {
        AggregateFunctions.Sum,
        AggregateFunctions.Count,
        AggregateFunctions.Average,
        AggregateFunctions.Max,
        AggregateFunctions.Min,
        AggregateFunctions.Product,
        AggregateFunctions.StdDev,
        AggregateFunctions.StdDevP,
        AggregateFunctions.Var,
        AggregateFunctions.VarP,
        New SqrtSumAggregateFunction()
    }

    Public Overrides Sub LoadSettings(aggregateDescription As PropertyAggregateDescriptionBase)
        MyBase.LoadSettings(aggregateDescription)

        Dim listAggregateFunctions = DirectCast(Me.GetType().BaseType.GetField("listAggregateFunctions", BindingFlags.NonPublic Or BindingFlags.Instance).GetValue(Me), RadListControl)
        listAggregateFunctions.DataSource = availableAggregateFunctions
    End Sub

To reproduce:
Try setting the value in the CellForamting event. 

Workaround:
class MySpreadExportRenderer : SpreadExportRenderer
{
    public override void SetCellSelectionValue(DataType dataType, object value)
    {
        base.SetCellSelectionValue(dataType, value);
        if (dataType == DataType.Number)
        {
            CellRange range = ((CellSelection)this.GetCellSelection()).CellRanges.ElementAtOrDefault(0);
            double d;
            if (double.TryParse(Convert.ToString(value), out d))
            {
                var cell = ((Worksheet)this.GetWorksheet()).Cells[range.FromIndex.RowIndex, range.FromIndex.ColumnIndex];
                cell.SetFormat(new CellValueFormat("#,##0.00"));

Until the feature gets implemented create a custom PivotFieldListVisualItem and translate each of the items individually:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
 
        this.radPivotFieldList1.RowLabelsControl.CreatingVisualListItem += ListControl_CreatingVisualListItem;
        this.radPivotFieldList1.ColumnLabelsControl.CreatingVisualListItem += ListControl_CreatingVisualListItem;
        this.radPivotFieldList1.ReportFiltersControl.CreatingVisualListItem += ListControl_CreatingVisualListItem;
        this.radPivotFieldList1.ValuesControl.CreatingVisualListItem += ListControl_CreatingVisualListItem;
    }
 
    private void ListControl_CreatingVisualListItem(object sender, CreatingVisualListItemEventArgs args)
    {
        args.VisualItem = new MyPivotFieldListVisualItem(this.radPivotFieldList1.ViewModel);
    }
}
 
public class MyPivotFieldListVisualItem : PivotFieldListVisualItem
{
    public MyPivotFieldListVisualItem(FieldListViewModel viewModel)
        : base(viewModel) { }
 
    protected override void CreateChildElements()
    {
        base.CreateChildElements();
 
        CommandBarDropDownButton btn = this.GetType().BaseType
            .GetField("button", BindingFlags.Instance | BindingFlags.NonPublic)
            .GetValue(this) as CommandBarDropDownButton;
 
        if (btn != null)
        {
            btn.DropDownMenu.PopupOpening += DropDownMenu_PopupOpening;
        }
    }
 
    private void DropDownMenu_PopupOpening(object sender, System.ComponentModel.CancelEventArgs args)
    {
        foreach (RadItem item in ((RadDropDownMenu)sender).Items)
        {
            // Validate and localize each of the items
            if (item is RadMenuItem)
            {
                item.Text = "MyText";
            }

Until the feature becomes available use the following workaround:

this.radChartView1.DataSource = this.radPivotGrid1;

        : base(pivotGridElement) { }

    public override void UpdateChartData()
    {
        base.UpdateChartData();

        foreach (ChartSeries series in this.ChartView.Series)

            CartesianSeries cartesianSeries = series as CartesianSeries;
            if (cartesianSeries == null)
            {
                continue;
            }

            cartesianSeries.PointSize = new SizeF(7, 7);

            BindingList<PivotChartModelPoint> newData = new BindingList<PivotChartModelPoint>();
            BindingList<PivotDataPoint> points = cartesianSeries.DataSource as BindingList<PivotDataPoint>;

            foreach (PivotDataPoint point in points)
            {
                PivotChartModelPoint current = new PivotChartModelPoint() { Group = point.PivotGroup };
                if (point.Value != 0)
                {
                    current.Value = point.Value;

How to reproduce:
   var data = this.dbContext.Orders.Where(o => o.OrderID > 10500).Select(o => new
            {
                Id = o.OrderID,
                OrderDate = o.OrderDate,
                ShipDate = o.ShippedDate,
                Freight = o.Freight
            }).ToArray();

this.localDataProvider = new LocalDataSourceProvider() {ItemsSource = data};

Workaround:
1. Instead of  ToArray call ToList
var data = this.dbContext.Orders.Where(o => o.OrderID > 10500).Select(o => new
{
    Id = o.OrderID,
    OrderDate = o.OrderDate,
    ShipDate = o.ShippedDate,
    Freight = o.Freight
}).ToList();

this.localDataProvider = new LocalDataSourceProvider() {ItemsSource = data};

2. Call the ToArray method but do not create anonymous objects.
var data = this.dbContext.Orders.Where(o => o.OrderID > 10500).Select(o => new PivotModel
{
    Id = o.OrderID,
    OrderDate = o.OrderDate,
    ShipDate = o.ShippedDate,
    Freight = o.Freight
}).ToArray();

this.localDataProvider = new LocalDataSourceProvider() {ItemsSource = data};

public class PivotModel
{
    public int Id { get; set; }

    public DateTime? OrderDate { get; set; }

    public DateTime? ShipDate { get; set; }

    public decimal? Freight { get; set; }
