Virtual Grid scrolling also has a problem when the user is fast scrolling downwards. The grid has a large virtualized dataset. Since Blazor Server's server-round-trip rendering model does not catch up in time with the scrolling, up or down, the data cannot be fetched fast enough to populate the grid That is why the rows looks greyed out or blank cells, if you remove the skeleton. It is very inconvenient for users to see greyed out data or blank cells when they are scrolling through the grid looking for specific data.
You can see the problem clearly in Telerik's example:

Go to the Example section and do a fast scroll up or down in the grid. Do you see the greyed out data?
Please fix ASAP.
Hi Bram,
I must admit that this feature is not planned for our next release in November. However, I see a recent spike in popularity (customer votes), so I notified Product Management to keep this item on their radar for 2026.

No solution in sight?
To properly use Grid Virtualization this seems like a necessity, so I find it strange this is not being addressed. One could argue this can be classified as a bug, because preloading is simply not working in some cases.
