RadCartesianChart hangs when using ScatterLineSeries with sliding ObservableCollection on iOS

Issue is only present on iOS.  Android and windows work as expected.

When using a ScatterLineSeries with a ItemSource set to an ObservableCollection the Chart control has a tendency to hang and lock the application when the ObservableCollection data slides (items are removed at position 0, and items are added to the end)

    When the issue occurs iOS Device log has entries such as:

    "default 09:31:45.095875-0500 myApp.Client.Mobile Hang detected: 0.39s (always-on hang reporting)"

    //this is called once during the setup of the control
    var data = new ObservableCollection<SeriesData>();

                ScatterLineSeries lineSeries = new ScatterLineSeries()
                {
                    DisplayName = series.Name,
                    XValueBinding = new PropertyNameDataPointBinding(nameof(SeriesData.XScaled)),
                    YValueBinding = new PropertyNameDataPointBinding(nameof(SeriesData.YScaled)),
                    ItemsSource = data,
                };
chart.Series.Add(lineSeries);
    //this is called periodically as new data is available to display
    public void AddSeriesData(IEnumerable<SeriesData> data)
    {
        float? min = null;
        float? max = null;

        lock (_data)
        {
            foreach (var d in data)
            {
                d.XScaled = d.X;
                d.YScaled = ((d.Y ?? 0) - d.Series.MinValue) / (d.Series.MaxValue - d.Series.MinValue) * 100;

                if (_data.TryGetValue(d.Series, outvar collection))
                {
                    collection.Add(d);
                   
                        max = d.XScaled;
                        
                        min = collection[0].XScaled;
                        while (max - min > settings.XAxisRange)
                        {
    //application will start to hang here, once items are removed from beginning of the collection
                            collection.RemoveAt(0);
                            min = collection[0].XScaled;
                        }
                }
            }
        }

        if (max != null)
        {
            xAxis.Maximum = max.Value;
            xAxis.Minimum = max.Value - settings.XAxisRange;
        }
    }
     
    public class SeriesData
    {
        public readonly Series Series;
        public readonly float? X;
        public readonly float? Y;

        public float? XScaled { get; internal set; }
        public float? YScaled { get; internal set; }

        public SeriesData(Series series, float? x, float? y)

    RadPopup doesn't close when navigating to new page

    I have a RadPopup with buttons that navigate to new pages via shell navigation.  When I click to navigate to the new page it remains open.  

     

    I would like the popup to disappear like the rest of the page, but when I press back, I would expect it to still be open

    RadListView EmptyView

    Good morning,

    Is there a way to format/customize what the empty view looks like? Currently it just says "No data", I wasn't sure if it was possible to add a custom message/style.

    Thank you!

    [Solved] Is it possible to create a Badge without content

    I am looking to have aBadge which is basically a styled label sitting on its own.

    I have tried adding a Badge View without content which wont work


    <telerik:RadBadgeView BadgeText="Archived" BadgeHorizontalAlignment="Start" BackgroundColor="#ffc107" BadgeTextColor="Black">
                           <telerik:RadBadgeView.Content>
                                
                            </telerik:RadBadgeView.Content> 
                        </telerik:RadBadgeView>

    Is there something I can do to just use the Badge as its own control?

    RadDatePicker not preventing the dark mode from applying, even for android the dark theme is restricted from app mainactivity - MAUI.

    Hi Telerik,

    In MAUI android app I am restricting the dark theme on my app from getting applied, for all the controls except for the RadDatePicker it works fine.

     

    NOTE:

    The RadDatePicker is not restricting the dark theme from getting applied in MAUI.

    Whereas in Xamarin it works fine.

    Below is the screen shot how it looks:

    Problem in the RadListView control when the collection of items is emptied.

    Hello I hope you can help me.
    I have a RadListView that gets populated from a collection provided in the ViewModel. Within the template there is a button to delete the selected element and it works fine, but when there is only one element left and I delete it, the application crashes.

    The xaml of the list

    [Solved] Can I link/associate a Label to a CheckBox to handle toggling the checkbox?

    Can we link/associate a Label to a CheckBox to handle toggling the checkbox?

    It would be useful to do this using  MAUI standard label or providing a Text property to show next to the Checkbox?

    Am I missing something? If this is not possible, its seems like a good feature?

    eg:

    [Solved] Line Series Won't Display

    I am trying to do a Line Series chart based on DateTimeAxis. Here is my XAML:

                        </telerik:RadCartesianChart>

    Here is where I create the observable collection:

    private async Task<ObservableCollection<ProgressSeriesData>> GetCategoricalDataFromDbAsync()
        {
            var entries = await _database.GetItemsAsync(); // Retrieve all entries from database
            ObservableCollection<ProgressSeriesData> data = new();
            var ID = 0;

            foreach (var entry in entries)
            {
                ProgressSeriesData progressSeriesData = new()
                {
                    Date = entry.Date,
                    Weight = entry.Weight,
                    ID = ID
                };
                data.Add(progressSeriesData);
                ID++;
            }

            return data;
        }

    and here is what is displayed in the app:

     

    I'm not sure why it won't plot the line for me? Here is what the data looks like in the model:

    Any and all help is appreciated :)

    NumericInputEntry in a ControlTemplate no longer obeys VerticalTextAlignment.

    This is a change in behavior from previous versions. Changing the value from Center to End, then back to Center in the debugger will change the alignment, but I haven't found a way to make it work in my app. At present the alignment appears to be Start.

    Example code:

            <ControlTemplate x:Key="RotationRadNumericInputControlTemplate">
                <Grid>
                    <telerik:RadBorder x:Name="PART_BorderVisual" BorderColor="Transparent">
                        <Grid ColumnSpacing="{StaticResource Spacing}" HeightRequest="50">
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="50" />
                                <ColumnDefinition Width="*" />
                                <ColumnDefinition Width="50" />
                            </Grid.ColumnDefinitions>
                            <telerik:NumericInputButton
                                Grid.Column="0"
                                HorizontalContentAlignment="Center"
                                VerticalContentAlignment="Center"
                                BackgroundColor="Transparent"
                                BorderColor="DarkOrange"
                                BorderThickness="2"
                                Command="{TemplateBinding DecreaseCommand}"
                                CornerRadius="0"
                                FontSize="{StaticResource MediumFontSize}"
                                IsEnabled="{TemplateBinding IsEnabled}"
                                Text="-"
                                TextColor="DarkOrange" />
                            <telerik:NumericInputEntry
                                x:Name="PART_Entry"
                                Grid.Column="1"
                                BackgroundColor="Transparent"
                                BorderBrush="DarkOrange"
                                BorderThickness="1"
                                ClearButtonVisibility="Never"
                                CornerRadius="0"
                                FontSize="{StaticResource MediumFontSize}"
                                HeightRequest="50"
                                HorizontalTextAlignment="Center"
                                InputTransparent="{TemplateBinding IsReadOnly}"
                                IsReadOnly="True"
                                Text="{TemplateBinding Value}"
                                TextColor="DarkOrange"
                                VerticalTextAlignment="Center"
                                WidthRequest="100" />
                            <telerik:NumericInputButton
                                Grid.Column="2"
                                HorizontalContentAlignment="Center"
                                VerticalContentAlignment="Center"
                                BackgroundColor="Transparent"
                                BorderColor="DarkOrange"
                                BorderThickness="2"
                                Command="{TemplateBinding IncreaseCommand}"
                                CornerRadius="0"
                                FontSize="{StaticResource MediumFontSize}"
                                IsEnabled="{TemplateBinding IsEnabled}"
                                Text="+"
                                TextColor="DarkOrange" />
                        </Grid>
                    </telerik:RadBorder>
                    <telerik:RadBorder x:Name="PART_FocusBorderVisual" BorderColor="Transparent" />
                </Grid>
            </ControlTemplate>
