Hello,

I have a Kendo UI Grid that loads 5000+ records.  The data is local data on the page, and the grid is handling it ok, but we'd like to improve performance.  I'd like to try loading the local data in batches of 100 as the user scrolls down the grid results.  I've seen the examples, but have not seen very many examples of MVVM implementations and the best way to approach our situation.  Could someone recommend the way to get virtual scrolling working with row batches?

Thanks in advance!

Hello Austin,

The desired result can be achieved using the same approach as for the jQuery Grid, the difference is only coming from the used syntax and the used ViewModel.

I made an example demonstrating this. In the DOM inspector can be observed how the rows are rendered in a batch of 100:

I can also suggest checking all of the requirements and limitations of the virtual scrolling feature:

http://docs.telerik.com/kendo-ui/controls/data-management/grid/appearance#virtual-scrolling

I hope this is helpful.

Regards,
Stefan
