Originally created by @OndrejUzovic on GitHub (Apr 9, 2024).

If RadzenDataGrid has set Virtualization and LoadData then the filtering (Simple and Advanced) works incorrectly.

The filter does not return correct values in some cases.

Here are simple steps to reproduce the issue:

  1. open the example from Radzen Component Page: https://blazor.radzen.com/datagrid-virtualization-loaddata

  2. click on the first line in DataGrid and using the key 'PgDown' on the keyboard go 3 pages down. (So that the first line has OrderID=10255.

  3. Open the filter on the column OrderID.

  4. Enter the value 10300 and click 'Apply'.

  5. The result is empty DataGrid with the message "No records to display." which is incorrect.

The correct behavior would be if DataGrid lists two items.

Please, would it be possible to correct this behavior?
