Hi there,
I have encountered this problem and can not fix the filter for these two columns.
If I use filter for these two columns: EnrolledNumber and WaitListNumber, I will get
Internet Server Error
Invalid Property or Field - 'EnrolledNumber' for type: Class
If I disabled both sortable and filter for these two columns, everything else will work fine.
How can I make the filter work and at the same time the program will not lag or become ridiculously slow?
The following is my code.
Model
EnrolledNumber = model.ClientClasses.Where(i => i.IsActive == true).Count();WaitListNumber = model.ClientClasses.Where(i => i.IsActive == false).Count();
[Display(Name = "Enrolled")]publicintEnrolledNumber { get; set; }[Display(Name = "WaitList")]publicintWaitListNumber { get; set; }View
columns.Bound(i => i.EnrolledNumber).Width(90).Title("Enrolled");columns.Bound(i => i.WaitListNumber).Width(90).Title("WaitList");Controller
publicActionResult Read_Classes([DataSourceRequest] DataSourceRequest request, boolisCurrent, boolisPending, boolisFinished){ IQueryable<Class> items = DbContext.Classes.Where(i => i.IsActive); if(!isPending) items = items.Where(i => !i.Pending); if(!isFinished) items = items.Where(i => !i.Finished); if(!isCurrent) items = items.Where(i => i.Finished || i.Pending); returnJson(items.ToDataSourceResult(request, i => newClassListViewModel(i)));}I also get
An exception of type 'System.ArgumentException' occurred in Kendo.Mvc.dll but was not handled in user code
in Visual Studio for first time
Thank you
