I am using the TelerikFileSelect component and I noticed that the user can select the same file multiple times and it just adds to the list

I was wondering if it's possible to maybe add logic to the OnSelect event that prevents the file from being added to the list of files under certain conditions such as duplication.

This could be achieved through cancelling the OnSelect event based on the desired condition - for instance, duplicated file names.

Add a parameter to the FileSelect component that enables users to control the visibility of the file list.

UI for Blazor version 5.0 improved the FileSelect Stream performance by removing legacy code that meant to support older .NET versions.

However, the Stream performance is still worse and the component works slower, compared to the standard Blazor InputFile.
