RadTimePicker objects remain in memory because, in the DateTimePicker class, it subscribe  on event Window.Current.SizeChanged but you never unsubscribe. So it generates memory leaks. The control will never be removed by the GC(garbage collector).



Source code:


 /// <summary>
        /// Initializes a new instance of the <see cref="DateTimePicker"/> class.
        /// </summary>
        protected DateTimePicker()
            var languages = new List<string> { this.CalendarLanguage };
            var calendar = new Windows.Globalization.Calendar(languages, this.CalendarIdentifier, ClockIdentifiers.TwelveHour);
            this.calendarValidator = new CalendarValidator(calendar);
            this.selectorUtcValue = DateTime.SpecifyKind(DateTime.Now, DateTimeKind.Utc);
            this.utcValue = this.selectorUtcValue;
            Window.Current.SizeChanged += this.Current_SizeChanged;

I am trying to use the chart control in multiple views: Meaning not just one window. I create several windows from the main window. It is not call "windows". It is a view.

It looks like the chart control fails:


System.Exception: The application called an interface that was marshalled for a different thread. (Exception from HRESULT: 0x8001010E (RPC_E_WRONG_THREAD))
   at Windows.UI.Xaml.Media.SolidColorBrush.get_Color()
   at Telerik.UI.Xaml.Controls.Chart.ContainerVisualsFactory.ChangeBrushesAccordingToAppTheme()
   at Telerik.UI.Xaml.Controls.Chart.ContainerVisualsFactory.PrepareCartesianAxisLineVisual(CartesianAxis axis, ContainerVisual lineContainer, RadRect layoutSlot, AxisType axisType)
   at Telerik.UI.X


Is there a way to fix it ?


to understand the concept of multiple views:


please advise me...

The "Foreground" property does not apply to the RadDatePicker icon .. it only applies to the text even though I followed what this page explains:

My XAML code is the following:

<Custom:RadDatePicker x:Name="FromDatePicker" HorizontalAlignment="Left" ValueChanged="DatePickerValueChange">
                        <Style TargetType="Custom:RadDatePicker">
                            <Setter Property="Foreground" Value="Orange"/>
                            <Setter Property="FontSize" Value="15"/>
                            <Setter Property="FontStyle" Value="Italic"/>
                            <Setter Property="Background" Value="Beige"/>
                            <Setter Property="BorderBrush" Value="Orange"/>

Attached image of the properties that only my RadDatePicker takes when running the application ..

When using Wrap Layout, with grouping and RowHeight is  not default the scrollbar size is incorrectly updated until all elements are measured once.

I can pull to refresh, but I only see the original pulltorefreshstyle. It seems to not raise the visualstates for RefreshStarting or Refreshing.

We have a simple RadDataBoundListBox filled with some elements.
We try to show/scroll to some specific element using the "BringIntoView" method.

EXPECTED result: The specified element should be shown.
ACTUAL result: Depending on the initial condition (if any manual scroll is performed in the RadDataBoundListBox or not), the result is:
- blank/empty RadDataBoundListBox if no manual scroll was performed
- Scroll to some element (usually "near" the requested one), but not exactly to the desired one, if there was some scrolling before invocation of the BringIntoView.

I noticed, that in your sample app, when e.g. in the DateTimePicker┬┤s input page, the back button brings you to the previous page and not to the page, where the DateTimePicker is located.

I saw that you are using a Popup to display picker pages. This leads you to the problem, that you cannot override the apps BackPressed bahaviour.

I could not find anything in your controls to check the Popup-state nor to manually dismiss the popup.
In my oppinion, this makes all your picker controls unusable for Windows Phone, as closing the popup is the default WP behavour.
What is you take on this?
