The grid scrollbar works nicely when the data is prepopulated however when filling the data from an event the scroll bar does not work.

 

Here, from the documentation, the scrollbar works as intended:

https://stackblitz.com/edit/react-el8uiz?file=app/main.jsx

(via https://www.telerik.com/kendo-react-ui/components/grid/scroll-modes/virtual/)

 

However, when filling the grid on an event the scroll functionality is lost:

https://stackblitz.com/edit/react-q2gnbn-yd3gsj?file=app/main.jsx

 

Is there something I am missing here when populating the data via an event? I am not necessarily concerned with virtual scrolling, this also happens without virtual.

Hello, John,

The issue occurs as the Grid scrollable functionality requires the Grid to have fixed height:

https://www.telerik.com/kendo-react-ui/components/grid/scroll-modes/#toc-getting-started

You can configure the scrollable behavior through the scrollable option which also requires you to set the height of the Grid through its style property.

In the provided example the height of 100% is not applied as not all parent DOM elements have height. Either set a fixed height or ensure that all elements have 100% height:

Thanks... I had tried setting the parent height to 100% in my app but I was using it display: grid, it appears the Grid component will only work with display: block then?

Nevermind, it works - needed to use 100% instead of auto for the row size.
