When grouping is used with virtualization expanded groups can not be collapsed, collapsed groups can not be expanded. The expand/collapse icon toggles but data does not change. When there are enough data to scroll down/up so that virtualization process loads some data, then the previous actions take place.
I tried to simulate the problem with a simple template project. I used your source codes from
https://blazor.syncfusion.com/documentation/datagrid/grouping and added just EnableVirtualization="true"
Attached video shows that it was working with version 22.214.171.124 but it is not working with the latest version (126.96.36.199). I tried both Visual Studio 2019 with .Net 5 and VS2022 with .Net 6, results are the same.
Can you please check this problem.
Thanks & kind regards
