My application is using Treelist and we have requirement to load level 4 node on demand.
because of it having maximum amount of data. so in order to boost performance we want to do async loading of level 4 node.
how can i achieve this in kendo angular treelist?

Hi Monika,
The TreeList relies on hasChildren and fetchChildren callbacks provided by the developer to load each next "level" of data for the expanded node:
https://www.telerik.com/kendo-angular-ui/components/treelist/data-binding/
https://www.telerik.com/kendo-angular-ui/components/treelist/data-binding/remote-data/
This means that all, but the root nodes are loaded on demand, and only the expanded items and their direct children are rendered in the DOM, regardless of whether the actual data is available on the client or not. So with both local and remote data, the TreeList is optimized, and will render only the nodes that have to be visible.
I hope this helps.
