Exception: System.NullReferenceException

Method : Boolean CheckBottomForIndentCell(Syncfusion.WinForms.DataGrid.DataRowBase, Syncfusion.WinForms.DataGrid.DataColumnBase)

Hi Florian,   
  
Thanks for contacting Syncfusion support.    
  
Sorry for the inconvenience. We are unable to reproduce the reported issue in our end. As you have mentioned it as occurring randomly, the provided stack trace is not sufficient to reproduce the issue. We have checked the method specified in the stack trace and there are no possibilities for getting Null Reference Exception in it. It is hard for us to reproduce the issue with the provided details.    
  
If possible, please provide us your issue reproducible sample or else the SfDataGrid settings you have used in your application with proper code snippet and a screenshot of your application and provide the scenario in which you are facing the issue. (For example, while performing grouping or anything like that). These details will help us to reproduce the reported issue in our end, so that we can find the exact cause for the issue and provide a prompt solution at the earliest.    
  
Regards,   
Mohanram A.
