Can telerik do this xamarin

 Histogram. Can different columns be clicked and then jump

I have a problem with my RadCalendar. Whenever I create a calendar in Agenda view and populate it with appointments, I get a visual bug that shows a colored square on top of the calendar.  This only happens in iOS and both in real phones and simulations.

Image 1 shows the calendar page without appointments and it loads normally. Image 2 shows the page when calendar is populated with appointments. You can get rid of the square by scrolling either up or down, 'till the square is no longer in view and then going back, this is shown in image 3.  

So far I have found that the color of the square is linked to the Dark/Light mode of the phone. When changing UIUserInterfaceStyle in Info.plist, to "Dark", the square is dark, when Light, it is white.

Dummy Appointment code:

  var date = DateTime.Today;

            this.Appointments = new ObservableCollection<Appointment>
        {
            new Appointment {
                Title = "Meeting with Tom",
                Detail = "Sea Garden",
                StartDate = date.AddHours(10),
                EndDate = date.AddHours(11),
                Color = Color.Tomato
            },
            new Appointment {
                Title = "Lunch with Sara",
                Detail = "Restaurant",
                StartDate = date.AddHours(12).AddMinutes(30),
                EndDate = date.AddHours(14),
                Color = Color.DarkTurquoise
            },
            new Appointment {
                Title = "Elle Birthday",
                StartDate = date.AddHours(9),
                EndDate = date.AddHours(11),
                Color = Color.Orange,
                IsAllDay = true
            },
            new Appointment {
                Title = "Football Game",
                StartDate = date.AddDays(2).AddHours(15),
                EndDate = date.AddDays(2).AddHours(17),
                Color = Color.Green
            },
        };

RadCalendar code:

     private RadCalendar TelerikCalendar()
        {
            LogWriter.LogWrite("Calendar: TelerikCalendar()");

            AgendaViewSettings agendaViewSettings = new AgendaViewSettings
            {
                MonthItemFormat = "MMM yyyy", //"MMM yyyy",
                DayItemFormat = "EEEE d.MMM", //"EEEE d.MMM"
                AppointmentItemTimeFormat = "HH.mm",
                IsHeaderSticky = false,
                StickyHeaderFormat = "MMM yyyy",
            };


            calendar = new RadCalendar
            {
                ViewMode = CalendarViewMode.Agenda,
                HorizontalOptions = LayoutOptions.FillAndExpand,
                VerticalOptions = LayoutOptions.FillAndExpand,
                AgendaViewSettings = agendaViewSettings,
                Margin = new Thickness(0, 0, 13, 0),
                SchedulingUiEnabled = false,
                IsAddAppointmentButtonVisible = false,
                DisplayDate = DateTime.Now,
                AppointmentsSource = this.Appointments,
                BackgroundColor = Color.Black,

            };

            return calendar;
        }

Hello,

Our android App compiles and runs normally. However, we are facing problems when compiling our application on IOS with an error that refers to the calendar component of telerik. The error is the following:

Gravedad	Código	Descripción	Proyecto	Archivo	Línea	Estado suprimido
Error		Can't resolve the reference 'System.IntPtr ObjCRuntime.DisposableObject::get_Handle()', referenced from the method 'System.Void TelerikUI.TKCalendarDayCell::DrawEvents(CoreGraphics.CGContext,CoreGraphics.CGRect)' in 'Xamarin.iOS, Version=0.0.0.0, Culture=neutral, PublicKeyToken=84e04ff9cfb79065'.

Thanks for the support.

I periodically can not connect to NuGet from Visual Studio. This is happening at the moment. Is the nuget.telerik.com server down?

When I use this in my browser...  

https://nuget.telerik.com/nuget

I am prompted for login, and after entering my credentials I see the page below

but in Visual Studio, it keeps on asking for my credentials when I try to use NuGet.

<?xml version="1.0" encoding="UTF-8" standalone="true"?>
<service xmlns="http://www.w3.org/2007/app" xmlns:app="http://www.w3.org/2007/app" xmlns:atom="http://www.w3.org/2005/Atom" xml:base="https://nuget.telerik.com/nuget/"><workspace><atom:title>Default</atom:title><collection href="Packages"><atom:title>Packages</atom:title></collection></workspace></service>

I've tried everything I can think of. The documentation says:

Occurs when the associated data (ItemsSource) has been successfully bound to the control or any data operation like Group, Sort or Filter is applied. This event is useful if an additional action is required once the data is ready to be visualized.

But in none of those circumstances is this event firing for me. I was particularly hoping for it to fire after Grouping, Sorting, and/or Filtering through the UI.

I read the topics on creating a custom DataGridTextFilterControl that is case insensitive and that works. But I want the text filter with the multiple clauses ANDed or ORed together (the text filters in the CompositeFilterDescriptor) to be case insensitive as well. 

I don't see a way to create a DataGridTypedFilter or a composite filter, since they're all internal.

There should be a way to set the case insensitive option lower in the object hierarchy, but I can't find it.

What is the purpose of the ApplyFilter command, which fires when you click "Filter" on the filter popup, if it provides no information about the filter that is about to be applied? It looks like I need a handle to the FilterDescriptor that is about to be applied and then I could dig down into the CompositeFilterDescriptor and set the IsCaseSensitive property before it's applied.

Any hints or options that I've missed?

Also, I'm Binding to a DataTable with AutoGenerateColumns=true, so setting up the filtering via XAML on a per column basis is not a solution for us.

Hello,

I have a problem regarding the custom appointments in UWP. When I specify my new appointment class and define a corresponding template the properties of my new class are not shown in the view. The standard properties of the Telerik appointment class are shown normally. This problem only occurs on UWP for me. On Android and iOS everything works as intended.

To show my problem I have attached an example project. In this project I have added my custom appointment class named TestAppointment. This custom class has one additional property Test which is set "Hello" for every appointment. To display this property I have added a label to my custom appointment template.

I hope my example project can help debug/fix this problem.

Thank you in advance

我的问题是：我需要点击多次才能返回上一页。结果 page1 跳转 page2 跳转 page3 跳转 page2 。我想要的是点击返回并直接进入 page1。但实际上是：点击多次返回，page2 ->page3->page2->page1

页面跳转为：Navigation.PushAsync

上面是导航栏
