Exception thrown when using Hierarchy Grid & Tab

The following error message appears when expanding a 2nd level Hierarchy Grid that is located in a Tab. I've attached the code to replicate the error with a screenshot showing the error. The code is adapted from https://blazor.syncfusion.com/demos/datagrid/hierarchy-grid?theme=bootstrap4, and I lightly modified it to include the Tab.

Tested on 18.3.42. Note that this error does not occur for 18.3.35.

Hi Renjith,

Thanks for your prompt response! I downloaded the sample and noticed that it is running on Blazor Server. Can you try it on Blazor Wasm to verify if it works on your end? I'm currently running on Blazor Wasm; apologies for not pointing that out earlier.

Regards,
Zhi Yuan

Any updates? Thanks! :)

Hi Zhi, 

Thanks for your update. 

We are able to face the reported problem in wasm application. We could face an exception which is crashing the application when expanding the DetailTemplate. We are currently checking this scenario from our side. We will update you further details in two business days. 

Until then we appreciate your patience.
