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.

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;
        }

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 ?

 

to understand the concept of multiple views:

 

https://docs.microsoft.com/en-us/windows/uwp/design/layout/show-multiple-views

 

please advise me...

I created a post in the forums but I don't know how much attention that particular forum gets.

I have created a simplified project on GitHub that reproduces the problem. 

I'm not sure if the problem is with the control or the framework, but my example project clearly demonstrates the problem. 

I suspect the problem is related to binding the Maximum property of the RadNumericBox. Items in the "Two" group have a higher maximum than items in the "One" and "Three" groups. While scrolling through the list, some items in the "Two" group get their values changed to the maximum from the other groups. It's also odd that the values that change are changed twice. The Debug Output window shows when and how each value is changed while scrolling through the list.

If any of this is not clear, I am happy to provide more detail, however, I'm sure the example project will make the problem clear.

Provide a tabstrip control that allows users to display content on tabs.

 - Tab content could use virtualization to avoid extra rendering
 - Follow themes from Telerik
