https://platform.uno/ has just reached version 2.0, please add support for using UI for UWP in an Uno project.

A DataStorage that can be used for both in Windows 8.1 and Windows Phone 8.1 apps.

Line Series is not drawn when Chart has only two data points. This is a bug in my opinion, this a line can be drawn from 2 points.

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 

Inconsistency in Line and Spline series performance

Resizing the window containing a CartesianChart with SplineSeries leads to some incorrect rendering between points:

creation of a line graph on a scatter point chart with gaps in the line when expected values are missing 

Something like this:

If we have a Chart with DateTimeContinuousAxis as horizontal axis, updating its Minimum and Maximum values should update the rendered in the Chart plot area data. However, if for some period (Minimum and Maximum range) there is no data, the current displayed data is not cleared.

If you populate the Chart with data through a SeriesDescriptor as explained here: How to Generate a Dynamic Series Using a Collection of Collections, the PointTemplate/PointTemplateSelector is not applied.

Currently the only way to apply different colors to the bars is through the ChartPalette. Provide an option to set the color according to the bound data item.  

updating data in real-time causes flickering when series are added through the series provider

Workaround: 
Add series to the chart without using the SeriesProvider option.

when applying the filter in a column where the scroll is on the right, all the scroll is reset to the left and the popup moves to another column. 

 

 

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;
        }

When the SelectionMode is set to Extended and we try to select items that are not currently visible using Shift + press only the Rows that are currently visible are selected.

In the RowDetails for a grid item I have a data template column as below.  If I check the checkbox on the first rowdetails item, every first rowdetails item in the entire grid has the check box checked.  Even if the SentToAcctFlag value for that item is False.  If I check one item in the row details I want only that one item to be checked.  Even refreshing the grid data using ItemsSource does not remove the first rowdetails item checked value for each parent record.

 

                                        <telerikGrid:DataGridTemplateColumn Header="To Acct" HeaderStyle="{StaticResource WorkOrderGridColHeader}" SizeMode="Fixed" Width="100"
                                                        CanUserEdit="True" CanUserSort="False" CanUserFilter="False" CanUserResize="False"  >
                                            <telerikGrid:DataGridTemplateColumn.CellContentTemplate >
                                                <DataTemplate>
                                                    <CheckBox IsChecked="{Binding SentToAcctFlag}" Margin="12,1,0,0" IsEnabled="True" Checked="SentToAcct_Checked" Unchecked="SentToAcct_Unchecked" />
                                                </DataTemplate>
                                            </telerikGrid:DataGridTemplateColumn.CellContentTemplate>
                                        </telerikGrid:DataGridTemplateColumn>
 

Data can come dynamically from JSON, XML, and SQL.  Without the ability to bind a grid to commonly used structures (like a Newtonsoft JSON, .NET DataTable or Dictionary), this grid has VERY limited use for apps that use modern ways of gathering and managing data (like JSON-Schema).

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 ?

please advise me...
