Apologies if this is not the right place to post this, but couldn't find a bug section for Kendo UI. The problem: [DataSourceRequest]DataSourceRequest Custom binding doesn't seem seem to add the WHERE into the generated SQL, when using DataSourceRequest.Filters ( i.e. myCollection.Where(request.Filters)). However, paging, and sorting working as expected. I would appreciate some feedback on this issue. Thank you very much, Panos.
