The combination of “Autofill” and “EnableVirtualization” slows down the component significantly

When we enable both the “Autofill” and “EnableVirtualization” properties, the dropdown component becomes extremely slow.


Sample: https://blazorplayground.syncfusion.com/embed/BZhJjQNWgQacvYSG?appbar=true&editor=true&result=true&errorlist=true&theme=bootstrap5

 


Replication steps:

  1. Run the sample.
  2. Search for “i” in the local data dropdown.
  3. Observe the issue.

Expected behavior: The component should remain fast when both properties are enabled.

Actual behavior: The component becomes very slow when both properties are enabled.
