You could still set a value for the VirtualItemCount. If you set a value that is greater than the actual number of items, RadGrid will show all available items plus empty pages (or whatever other content you set) for the items that exceed the actual number.
For example you have a data source with 9'000 items and you set VirtualItemCount to 10'000. If your page size is 1000, the grid will render 10 pages and the last page will be empty (or with NoRecordsTemplate if you're using such).
