ListView virtualization

Hello

 

Would be great to have a virtualization option on the ListView component, as paging is already supported.

 

Then we can achieve the "google images" type infinite scrolling without killing performance by loading all without paging...

 

Below example where we want users to be able to infinitely scroll through images based on keywords;

Hi Philip,

In general, virtual scrolling requires that the component that does that virtualization has control over the rendering of the items, and that those items have the same dimensions. In the listview, that's not the case, which is why virtual scrolling can't really fit a listview.

What I can suggest you look into is using one of the following:

Apart from that, the listview has built-in paging that you can use to reduce the size of the DOM and speed up the UI. It even offers an OnRead event that lets you implement load-on-demand (server operations such as paging, sorting, filtering) so you don't have to load all the data.
