Problem with Grid action - Count must have a non-negative value

the `GridModelBuilder` will `OrderBy` key ("id" in your case), and use `Skip` and `Take` for paging, do you get the same error if you don't call `Take(200)` ?

without Take(200) - everything works correctly.

think if you will call `.ToList()` after `Take(200)` it will work, the grid is already doing paging so you shouldn't need to call `Take(200)`, perhaps an alternative for you would be to edit the model returned by GridModelBuilder and cap the number of pages var model = new GridModelBuilder(...).BuildModel(); model.PageCount = model.PageCount > 10 ? 10 : model.PageCount; return Json(model.ToDto()); I'm guessing this is what you want
