PivotGridControl when used in TopSummary Scenario produces an exception :
Exception thrown: 'System.NullReferenceException' in Syncfusion.PivotAnalysis.Base.dll
Object reference not set to an instance of an object. (Method Name : ProcessRowSums Class: PivotEngine)

Architecture used in my application:

1. get Data from server in the form of a list and Bind item source of pivotgrid to the list on click of a button
2. Refresh the data (here the error occurs in the topsummary scenario)
3. Collapse rows and columns in the data_refreshed event.

Hierarchy:
 8 rows hierarchical level and 2 in column hierarchical level

Thanks,

Hi Chaitanya, 

Thank you for contacting Syncfusion Support. 

We are unable to reproduce the reported issue – “Exception thrown when using the layout as TopSummary”. We have tested the reported scenario in our working sample which was prepared based on the architecture shared in your previous update. 

We have prepared the sample with the below aspects. 
  1. Binding a list of data to items source of PivotGrid when clicking the button (Refresh).
  2. Changing the layout as TopSummary through Combo-Box.
  3. 8 items used in PivotRows and 2 items in PivotColumns.

Please find our working sample from the following location. 
 
IMPORTANT NOTE: 
1. Can you please provide your working sample or modify the shared sample to reproduce the reported issue?   

2. Also please let us know your product version along with the sample, so that it would be helpful for us to proceed further. 

Regards, 
Sabaridass R.

In the example you've provided, please add the following line

this.Pivot.PivotEngine.EnableOnDemandCalculations = true; to the constructor of the MainWindow.


It will generate the specified exception.
