We are needing the virtual scrolling to work for our project and also need the detail rows working. The explaination of the problem was described on the forums here: http://www.kendoui.com/forums/ui/grid/hidden-detail-row-when-using-detail-template-and-virtual-scrolling.aspx
Hello,
Utilizing the Kendo UI Grid with virtual scrolling and hierarchy/detail templates is a known limitation, however the Kendo UI team developed an endless scrolling grid which provides the same look and feel as the virtually scrollable one in 2017 R3 (v. 2017.3.913) without this limitation:
Demo: https://demos.telerik.com/kendo-ui/grid/endless-scrolling-local
Documentation: https://docs.telerik.com/kendo-ui/controls/data-management/grid/scrolling/endless-scrolling#using-with-hierarchy
Let us know what your thought are and if the endless scrolling grid meets the requirements you have.

Rows virtual scrolling feature is unusable without this fix! Really!
This still doesn't work in 2015.
We have a lot of "drill into" grids that we won't be able to use kendo for until this is addressed. Every time they drill down, they lose data out of the bottom of the grid and if it is the last row they are drilling in to, you can not see any of the detail grid.
