Workaround: handle the UpdateCompleted event and explicitly set the properties to true

public LocalDataSourceSerializerForm()
{
    InitializeComponent();

    this.radPivotGrid1.AutoExpandColumnHeaders = false;
    this.radPivotGrid1.AutoExpandRowHeaders = false;

    this.radPivotGrid1.UpdateCompleted += radPivotGrid1_UpdateCompleted;

Until the feature gets implemented use custom PivotGridPrintStyle:

How to reproduce:
   var data = this.dbContext.Orders.Where(o => o.OrderID > 10500).Select(o => new
            {
                Id = o.OrderID,

                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

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

public class PivotModel

    public DateTime? ShipDate { get; set; }

If you have an object with string property and for all the available objects in the RadPivotgrid you have numeric values for this property with leading zero digits (e.g. "002"), it is exported in Excel as a numeric cell.

To reproduce:

1. Add a RadPivotGrid and  change its theme to TelerikMetro. This theme uses Segoe UI font for its cells.
2. Export the RadPivotGrid.
3. You will notice that the font is applied to some of the cells, but for others, e.g. Grand Total the default font is set to Microsoft Sans Serif

Second scenario: use Demo application PivotGrid >> Export to Excel example. Use ControlDefault theme.
1. Ctrl + H to show the spy.  Check font for row  "Jun-1 >> Sum of Net", column "Printer stand >> 1 Free with 10".  The font is Segoe UI.
2. Run the export and check the same cell in Excel. Its font is Microsoft Sans Serif.

Workaround: use the PivotExcelCellFormatting event to specify the font.
