I'm using both mvc wrappers and the pure js versions depending on the need.
Yes - I have a datasource that is shared between a grid and a listview. You can see a screenshot of it here:
The 4th button on the right (looks like a rubik's cube above the grid size column) is used to toggle between grid view and list view.
Everything works great (filtering,sorting) works fine - except if I kick in grouping on the grid - and when grouping on the grid, the listview will error out due to the item template used.
I haven't looked at the Kendo source - but I imagine when grouping, data maybe be put in different sub arrays to reflect the proper data grouping (don't quote me on that :-)).
All I was getting at was that it would be nice if listviews could work with a datasource that has grouping in place - basically the same ideal as grids.
