Hi Domingo,

If you notice in the DataListViewModelBase, we have an overridable Repository property. By default, Crosslight supports WebAPI repository as we think it provides a leaner queries and a more flexible REST-based requests. We highly recommend you to migrate to the WebAPI infrastructure if possible. However, if this is not possible, you will require to override the Repository property and provide the custom implementations of the repository that will handle the incremental loading of your applications.

Judging by the method definfition (public Task<IEnumerable<MachineItem>> GetListOfMachines()), it seems that is not quite possible, unless, if you could provide some sort of range as the "range" for the query. Perhaps something like GetListOfMachines(int startIndex, int endIndex), but still, you will need to handle the custom implementations. The DataListViewModelBase has properties that will help you to achieve the incremental loadingprocess, as outlined in  the documentation: http://developer.intersoftpt.com/display/crosslight/Enabling+Incremental+Loading.
