Hi
I use a dynamic dataset to create a Datagrid and it all works well.
However filtering/sorting or refresh gives the following error. I then updated my version of Radzen Blazor components (I was on 6.018. And version > 6.1.1 now gives that error immediately and I get no rows rendered.
blazor.web.js:1 [2025-03-03T15:07:07.751Z] Error: System.IndexOutOfRangeException: Index was outside the bounds of the array.
