Hello, Rafal,

To use the endless scrolling there should be met the following conditions:

> The scrollable.endless should be set to true.

> The height of the grid should be constant.

> The total rows height/width should exceed the grid height/width. 

In my previous post, I incorrectly mentioned that the page size of the Grid needs to be three times larger than the number of visible rows. Actually, for the endless scrolling, this particular volume is not explicitly expected. It is recommended for the virtual scrolling.

Only if the conditions above are met the scrollbar will be active and the endless scrolling possible for use. If you can share with such an example that meets the conditions above but does not function correctly, we can reopen this bug report.

Hello, Rafal,

Please accept my apology for the delayed reponse.

When bound to remote data, the Grid serialized only the items for one page. When the user scrolls to the end of the list the Grid sends an AJAX request to get the items for the next page. You could refer to the following article on the Kendo UI Grid documentation: https://docs.telerik.com/kendo-ui/controls/data-management/grid/scrolling/endless-scrolling

For better user experience we recommend the page size of the Grid to be over three times larger than the number of visible table rows in the data area.

In your example, I would suggest setting the page size with more items or setting the grid height smaller, otherwise a scrollbar will not be generated and so the users will not be able to get to the rest of the data.

I would also suggest setting width to the column "Product Name". This will keep the column visible on horizontal scrolling.

I hope this helps.
