I recently created a new project with the latest Kendo code. The project has numerous grids and most of them use filter rows. I do all my grid filtering, sorting, paging, and grouping on the server side using the DataSourceRequest object that the grid passes through the grid's data source read action. I noticed that in the latest version of Kendo, there are four new filter operations: Is Null, Is Not Null, Is Empty, and Is Not Empty. Those seem like good options to have for filtering. The problem is that, in their current form, they're unusable for server side filtering. The filters in the DataSourceRequest object are not providing the critical Member property when using any of the new operations so I have no way of knowing which columns in my database the new filters should be applied to. Can you tell me if you are aware of this issue and, if so, when you will fix it? Also, is there a way to keep those operations (or any of the others for that matter) from showing up in the list of filter operators? Thanks.
