剑道网格过滤器适用于“包含”但不等于

Question

I can't get the equality filter ("is equal to" or "is not equal to") to work on the "Request Status" column in a kendo grid. I can use it on other columns in the grid, such as Buyer.

But the "contains" filter works on the "Request Status" column. Why doesn't equals work?

Example: Contains "Rejected" filters correctly. Equal to "Rejected" does not.

For whatever reason, it works to assign the ItemRequestStatusId to a variable, and then use that variable in the cell.

Change to HTML:

 @foreach (var itemRequest in this.Model)
            {
                string status = (itemRequest.ItemRequestStatusId == Portal.BusinessModel.Entities.ItemRequestStatusId.Draft ? "Draft" :
                            (itemRequest.ItemRequestStatusId == Portal.BusinessModel.Entities.ItemRequestStatusId.MerchandisingReview ? "Merchandising" :
                            (itemRequest.ItemRequestStatusId == Portal.BusinessModel.Entities.ItemRequestStatusId.SpacePlanningReview ? "Space Planning" :
                            (itemRequest.ItemRequestStatusId == Portal.BusinessModel.Entities.ItemRequestStatusId.DataIntegrityReview ||
                                itemRequest.ItemRequestStatusId == Portal.BusinessModel.Entities.ItemRequestStatusId.DataIntegrityFinalReview ? "Data Integrity" :
                            (itemRequest.ItemRequestStatusId == Portal.BusinessModel.Entities.ItemRequestStatusId.VendorRepReview ? "Vendor Rep" :
                            (itemRequest.ItemRequestStatusId == Portal.BusinessModel.Entities.ItemRequestStatusId.Approved ? "Approved" :
                            (itemRequest.ItemRequestStatusId == Portal.BusinessModel.Entities.ItemRequestStatusId.Rejected ? "Rejected" : ""
                            )))))));
                <tr>
                    <td>@itemRequest.Id</td>
                    <td>@status</td>
                    <td>@itemRequest.GetAuthor().FirstName @itemRequest.GetAuthor().LastName</td>
                    <td>@(itemRequest.GetBuyer() != null ? @String.Format("{0}", itemRequest.GetBuyer().Name) : "")</td>                    
                    <td>@itemRequest.Upc</td>
                    <td>@itemRequest.BrandCode</td>
                    <td>@itemRequest.Description</td>
                    <td>@itemRequest.CreateDate.ToShortDateString()</td>
                    <td>@(itemRequest.LastUpdateDate.HasValue ? ((DateTime)itemRequest.LastUpdateDate).ToShortDateString() : "")</td>
                </tr>
            }
