Lazy loading or virtualized view of items in FileManager

We are going to evaluate on EJ2 and it's Javascript and React version of FileManager.

We may list a folder with 10000 items or more.

I'm worry on performance of loading and rendering.

Does it support loading on demand?

Hi John,

Yes, In File Manager component, we have enabled Virtualization support in the package version. It will scroll the items in details view or large icons view to load the folders/files dynamically to improve performance. To use the virtual scrolling feature, inject the Virtualization module using the FileManager.Inject(Virtualization) section, then set the enableVirtualization property to true.

You can find a working demo at the below link.
