I have a Kendo MVC Grid. In which I have Pagination which is Server Event and a Filter Option which Calls the Read of the Grid. But when I Include a Grouping It say's a error in the Browser Console " Cannot readproperty 'length' ". I have tried the solutions given on the other forum threads. 
1)Giving .ServerOperation(false) which makes Pagination and Filtration nonfunctional. But  I need .ServerOperation(true) to make my Pagination and Filtration to work.
The code is below :

#######################Kendo Grid#############################

 @(Html.Kendo().Grid(Model.UpcomingMilestone)
                                                          .Name("grd_UpcomingMilestone")
                                                          
                                                          .Columns(columns =>
                                                          {
                                                              columns.Bound(c => c.ProjectName).Title("Project Name").Groupable(false);
                                                              columns.Bound(c => c.NextMilestone).Title("Next Milestone Name").Groupable(false);
                                                              columns.Bound(c => c.NextMilestoneDate).Title("Next Milestone Date").ClientTemplate("#= kendo.toString(NextMilestoneDate, \"MM/dd/yyyy\") #").Groupable(false);
                                                              columns.Bound(c => c.ProjectManagerName).Title("Project Manager Name").Groupable(false);
                                                              columns.Bound(c => c.TeamLeadName).Title("Team Lead Name").Groupable(false);
                                                              columns.Bound(c => c.WeekStartDate).ClientTemplate("#= kendo.toString(WeekStartDate, \"MM/dd/yyyy\") #");
                                                          })
                                                                  .Pageable(pageable => pageable
                                                                    .Refresh(true)                                                                   
                                                                    .ButtonCount(5)) // Enable paging
