Our application is rendering approximately 300,000 records with 10 columns. We are investigating the possibility of using Virtualization over Paging but are experiencing a slow and flickering render on scroll.
I was wondering if you had any plans to expose the OverscanCount parameter of Microsoft.AspNetCore.Components.Web.Virtualization.Virtualize so we could attempt to tweak the balance between LoadData frequency and render time.
It will be part of our next update early next week.
Will this be added to RadzenDropDown?
Now, when scrolling, the database is accessed every 4 lines, with a request for 13 records. When scrolling through 200 rows, that's 50 requests. I would like to make 4 requests of 50 lines or something like that
Wow, very fast! Thank you! Waiting for the release
Glad we switched from Mudblazor to Radzen 
Can we get "placeholder" in virtualization? To show that items are loading
Now:
expect:

Also with virtualization checkbox of already marked elements is reset, an example in git
