You can use the detailExpand event handler to apply the animations, provided by Kendo UI (or custom ones), on the DOM element, containing the detail Grid (available via e.detailRow), e.g.:
I added the "nova" css. The result does not fade in the detail row. Rather there is a pause but it just pops in and does not fade in.

Hi Reid,
The described effect happens the first time a Grid row is expanded, because the fading in of the detail Grid coincides with the loading of its data.
You can observe that the next time the row is collapsed and expanded again, the detail Grid fades in more smoothly, as it already exists and does not have to be created again. Increasing the animation duration will make the process easier for observing:
