I have a field i am string filtering on.   This field had people's names in it.  One of our users is named "Jason Nulls".  When we searched for "contains" null, it crashed the ToDatasourceResult in the controller.  Comparing to a filter for a different user whose name starts with Barr, you can see the difference in the generated filters in this image.  

Please implement native DateTimeOffset support to the filtering and sorting in the MVC Kendo grid.

It would be great to have the option of ForeignKey column bound to a remote data source. This would be useful to get the data asynchronously from a table in database and all the changes made to that table in realtime without having to get that data locally.
