Hi - I get an "Object reference not set to an instance of an object" error, from Syncfusion.Blazor.dll, when I in a Grid try to edit a column and have "FrozenColumns" in same grid. It is to the right of the "frosenline" that this occurs.

Can you make the att. example work? 
It seems that you have only tested with textboxes. Numbers, BooleadEdits and others dont work.

Hi Soren,  

Thanks for sharing the sample.  

Query: “It seems that you have only tested with textboxes. Numbers, BooleadEdits and others dont work” 
 
In the provided sample, we have validated the reported issue by removing the EnableAutoFill property (AutoFill is not working with FrozenColumns) from Grid. We are able to reproduce the reported issue while saving the changes in Grid (i.e.) Exception is thrown while trying to save the changes. Issue occur due to RegexPattern Validation rules defined for Weight column (numeric). 

We have confirmed it as a bug and logged the defect for the same “Exception occur when defining the RegexPattern Validation for numeric columns”. Fix for the issue will be included in our weekly patch expected to be rolled out on or before  14th October 2020. 

You can now track the current status of your request, review the proposed resolution timeline, and contact us for any further inquiries through this link.       
   
  
Till then we appreciate your patience.

Hi Vignesh, can I have you to remove the "FrozenColumns" and the "regex" code, run the project, and try to click the boolean column?

VN Vignesh Natarajan Syncfusion Team October 9, 2020 04:16 AM UTC

Hi Soren,  

Query: “can I have you to remove the "FrozenColumns" and the "regex" code, run the project, and try to click the boolean column?” 
 
Yes to edit the Boolean column, kindly remove the FrozenColumns property and RegexPattern ValidationRules from the attached project. And also kindly upgrade your project to our latest version (18.3.0.38v) Nuget package (Syncfusion.Blazor) to resolve the exception thrown while clicking the Boolean column.  

For your convenience we have attached the modified project below  


We will get back to you once the reported issue is fixed and included in weekly patch releases. Till then we appreciate your patience.

I have downgrated to version 18.3.35, from 18.3.38, and still have "Object reference not set to an instance of an object" on the treegrid. 
Can you comfirm this error?

Query: “I have downgrated to version 18.3.35, from 18.3.38, and still have "Object reference not set to an instance of an object" on the treegrid.  Can you comfirm this error?” 
 
Yes. We are able to reproduce the reported issue at our end using 18.3.0.35 version while trying to edit a Boolean value In Grid component. We have resolved the issue internally and included the fix in our 18.3.0.38 release. But you have mentioned that you are facing issue in TreeGrid. So kindly confirm whether you are facing the reported issue in Grid component or TreeGrid component.

Hi Vignesh, I have tried versions 18.3.35, 18.3.38, 18.3.40 and 18.3.41. It seems all of them have issues, x.x.35 and x.x.38 with TreeGrid, and boolean cells, x.x.40 and x.x.41 works local in debug-mode, but deployed to an Azure Appservice it gives an "Unhandled exception in circuit 'PxFINPMt20kdsgo_RjHnx-6dQF4xkisDlzirlotE1Q4'.System.NullReferenceException:
