Exception when clicking on any node of the treeview

Hello,

I have updated my solution (Blazor Server App) into the latest version of Syncfusion (20.2.0.49) and when I 'm clicking on any node of the Treeview I'm getting the following exception.  Do you have any solution for the below?



Thank you in advance.

Best Regards,

Andri Solomou

Hi Andri,


Greetings from Syncfusion support.


We have prepared a Blazor TreeView sample with the shared code in the 20.2.49 version. But we were not able to replicate the reported issue at our end. The TreeView works properly without any errors on our end. For your reference, we have attached the sample.

We suggest you check whether you mapped the proper Script reference in the sample. If the issue still persists, please replicate the issue in the above shared sample. Share us the .NET version and the exact steps you followed to replicate the issue. These details would help us assist you promptly.

Please note that I'm receiving the same issue when I use the variable of the ExpandedNodes property into Treeview.
