@enchev Yes, I have tried that but the problem is there in the demos as well
If you see in this screenshot the vertical scrollbar of the grid always starts from the header and not from the first row, i want it to start from the first row
and previously you had this feature as well
this was taken from DataGrid Header Alignment With Scroll - Radzen.Blazor Components - Radzen
and you can see the vertical scrollbar starting from first row
