Available in the 2017 R1 Release (2017.1.117).

Add options for showing items with no data as in Local data provider.

Hour, minute, second.

I want to create CustomDistinct aggregate, I did it successfully for LocalDataSourceProvider, and I need it also for QueryableDataProvider.

See: http://www.telerik.com/forums/custom-aggregate-for-queryabledataprovider

Add support for Hours/Minutes/Seconds steps. Also, add a DayNumber option.

When you apply an average aggregate function (for example via the RadPivotFieldList control) a VerificationException is thrown. The exception message is: "Operation could destabilize the runtime."

All of the functionalities inside the column headers are located in the RadPivotFieldList. Add the same behavior in the RadPivotGrid.

Currently the LocalDataSourceProvider has such support and we can consider introducing the same functionality in the QueryableDataProvider.

Currently, the dates in the filter dialogs of RadPivotList are using invariant culture format. Allow the format to respect the currently applied application or data provider culture.

Currently, changing the visibility of the Expand/Collapse icon, via style, will apply it to all of the elements which are of type PivotGroupHeader.  

InvalidDataContractException is thrown when serializing the LocalDataSourceProvider with a DataContractSerializer and a calculation (TotalFormat) is applied.

Currently, the string format (used in the cells generated for the  from the DateTimeGroupDescription) is determined automatically based on the selected Step (Day, Month, etc.). Add an option to easily set custom string format.

At this moment, you can change the format only if you create a custom description and override a considerable amount of code. This is shown in the following SDK example: https://github.com/telerik/xaml-sdk/tree/master/PivotGrid/CustomDateTimeGroupDescription

 

If we apply a label GroupFilter to a RowGroupDescription/ColumnGroupDescription (through the GroupFilter property or through the RadPivotFieldList) matching groups from both the rows and columns are filtered out. 

Currently, RadPivotGrid supports UI-based selection, which highlights the selected cells. However, the API that handles this is internal and it cannot be used to manually access the selection. Add API that allows to get the selected items and to update the selection.

Add average/min/max built in functions for DateTime and TimeSpan values
