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.

When you try to resize the column through the header thumb, there is a minimum width set to 100. We should consider making the mechanism consider the minimum column width set.

Double-clicking the thumb results in the correct behavior.

Available in the R1 2018 release. 

In some specific scenarios, scrolling the RadDataGrid results in IndexOutOfRangeException

Exception = {System.IndexOutOfRangeException: Index was outside the bounds of the array.

In a scenario where you have lots of columns so that a horizontal scrollbar is present and you try to resize columns which are not visible at the beginning(need to scroll to view them) ->  the resizing is not working as expected and the view is jumping. 

Available in the R1 2018 release.

Hey,

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?

Cannot use spaces in editors within groups.
Instead space triggers expand/collapse state

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

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 

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>
