Apologies if this has been asked before...

 

I have a grid where we display a matrix with checkboxes that users can click to check/uncheck items. As long as there aren't  ~ > 1000 rows and columns everything is fine. I turned on virtual scrolling like this:

scrollable: { virtual: true }

 

and like this:

scrollable: { virtual: "rows, columns" }

neither seems to do much when you have 2500 columns and 3000 rows.

 

Is this even doable? Is there an example of this somewhere I could see?

Hi, Matt,

Are you referring to the selectable column with multiple selection?

If you are, then I am afraid persisting the selected items is nou possible unless they are bound to a property which is part of the data. This is listed in the known limitation section:

https://docs.telerik.com/kendo-ui/controls/data-management/grid/scrolling/virtual-scrolling#known-limitations

As an alternative, you may try endless scrolling instead:

https://docs.telerik.com/kendo-ui/controls/data-management/grid/scrolling/endless-scrolling

In case I have misunderstood the question, please elaborate what is the desired outcome and what is the current behaviour. A simple dojo with mocked data would also be helpful.
