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
End Class

Need to have the ability to resize the height of the aggregate area along with other features that will help the user see/discern the labels properly

Request is to have the ability preferably using a mouse drag to change the height of the column headers in the grid. We can already do that for data rows of the grid, but it is not possible currently to do the same for the header row.

Until the feature becomes available use the following workaround:

MyPivotGridChartDataProvider chartProvider = new MyPivotGridChartDataProvider(this.radPivotGrid1.PivotGridElement);
this.radPivotGrid1.ChartDataProvider = chartProvider;
this.radChartView1.DataSource = this.radPivotGrid1;
this.radChartView1.ShowLegend = true;
this.radPivotGrid1.ChartDataProvider.SeriesAxis = Telerik.Pivot.Core.PivotAxis.Rows;
this.radPivotGrid1.ChartDataProvider.GeneratedSeriesType = Telerik.WinControls.UI.GeneratedSeriesType.Line;

public class MyPivotGridChartDataProvider : PivotGridChartDataProvider
{
    public MyPivotGridChartDataProvider(RadPivotGridElement pivotGridElement)
        : 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;
                }
                else
                {
                    current.Value = null;
                }

                newData.Add(current);
            }

            cartesianSeries.DataSource = null;

            cartesianSeries.CategoryMember = "Group";
            cartesianSeries.ValueMember = "Value";
            cartesianSeries.DataSource = newData;
        }
    }
}

public class PivotChartModelPoint
{
    public string Group{ get; set; }

    public double? Value { get; set; }
}

You save 2 config, one with Report filter (1), one without (2), if you load first (1), if puts report filter correctly, but if you load then (2) - report filter still as on (1).
Also, if you load config with ShowFilterArea=true - it  stays visible if you load another config with ShowFilterArea=true 

Hello Alex,

While investigating the reported behavior I managed to isolate an issue in the Save/Load API of RadPivotGrid regarding the ShowFilterArea property. The default value of this property is not serialized, however this can be altered by adding a serialization meta data to the XmlSerializationInfo instance of the pivot. In this scenario the engine did not respect the added new data. Here is the feedback item and you can subscribe to it: http://feedback.telerik.com/Project/154/Feedback/Details/196273-fix-radpivotgrid-the-saveloadlayout-string-overload-does-not-use-the-radpivotg. The item is already in development and a permanent fix will be available with our next release.

Regarding the empty filter descriptions, in order to serialize them one should work with a DataProviderSerializer class. Currently our engine does not save the empty filters and we will consider modifying it so that even if the collection is empty it also be serialized.

I am attaching to this post a sample project with which you would be able to achieve both of your tasks. Please note that the serialization API of the LocalDataSourceProvider uses the DataContract and you would need to use our .NET 4.0 assemblies.

I hope this helps. In case you need additional assistance please write here or open a support ticket.

Regards, 
Hristo

Add functionality which will allow the end users to edit the aggregated data. The new values should be passed back to the business logic of the application which will decide how to divide the new value across underlying records.

When a filter dialog is shown (Report Filter or Label Filter) for OLAP Hierarchy, it contains the items only for the selected level. Instead items from all levels could be visible, so you won't have to open additional dialogs to filter them (show them like a tree).
