TelerikChartAxisBorderBrush is not applied when setting in Dark Light ThemeResources from the Telerik Theme Resources https://docs.telerik.com/devtools/universal-windows-platform/common/teleriknamedbrushes 

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:

 

https://docs.microsoft.com/en-us/windows/uwp/design/layout/show-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: https://docs.telerik.com/windows-universal/controls/raddatepicker-and-radtimepicker/styling/raddatetimepickers-explicitstyling

My XAML code is the following:

<Custom:RadDatePicker x:Name="FromDatePicker" HorizontalAlignment="Left" ValueChanged="DatePickerValueChange">
                    <Custom:RadDatePicker.Resources>
                        <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"/>
                        </Style>
                    </Custom:RadDatePicker.Resources>
                </Custom:RadDatePicker>

I have a radgrid and when I scroll down it throws this error, but I'm not sure where the error is coming from or how I can help resolve it.

This is a UWP app and I'm debugging in VS 2017 15.3 on windows 10 creators edition.

When you have several series(ScatterLineSeries reported but it happens with others as well) in the RadCartesianChart and you clear the Items of one of them by calling the Clear() method - the line is not redrawn and it shows the old data. 

When using shp and dbf files with ~130MB size, it takes minutes to load the map

The uwp radlistview vertical scrollbar disappears when focus is lost -
I think I need something like 
https://www.telerik.com/forums/listview-width-with-or-without-vertical-scrollbar
 <telerik:RadListView.Commands. ListElement.Scroller.Scrollbar.FillElement.Visibility

But I may be missing something?

Testing the Telerik RadialMenu control in the UWP app ,  when you click on the radialmenu the control flickers for the mouseclick event on desktop.  plse consider changing the "flicker" to something more like a keypress , a image blur or something else. Or slow down the flicker considerable , your effect looks more like a defect of image rendering at the moment. 

When you set the Required attribute on a property of an object that is used for the DataForm, it is not respected by the control.

We have a simple RadNumericBox control.
We what to add a number with leading decimal separator (omitting the leading 0) for example .59 .

EXPECTED result: The entered number is 0.59 .
ACTUAL result: The decimal separator is added after the first added digit, i.e. the entered number becomes 5.9 .

After multiple control reload the memory is not released.

Declined: Currently UWP does not have an ImageEditor control. On the following link you can find a feature request where you can vote for introducing such a control and track its status: https://feedback.telerik.com/Project/167/Feedback/Details/201118-new-control-image-editor-port-to-uwp
