Virtualized Components scroll to specific item

I am trying to make a Virtualized component scroll to a page containing a pre-selected item after first render (or when ready)
I appreciate this is not supported by the library, but as a new user of Radzen, I am struggling find a way.

Working on RadzenDataGrid, I add a UniqueID to all TR using RowRender
I can use JS Interop to scroll to a rendered row

I can render the items that contain the SelectedItem using LoadData, but cannot work out after this, how to not break Virtualization scrolling with a simple hand-made LoadData!

I have tried to create my own ItemsProvider without actually getting it to be invoked.

Also I have tried to invoke the underlying ItemsProvider with a suitable ItemsProviderRequest but can't get this approach to render/scroll to the appropriate position.

Looking for a hint on how to attack this, or just someone more knowledgeable to say why this is more difficult that it seems!

All help gratefully received

As far as we know this cannot be achieved. You can search for help also on StackOverflow where there are more posts related to framework components like Virtualize.
