Hi,

I was checking your updates on my mobile and the app crashed.

Steps:

1. Go to Calendar & Scheduling

2. Agenda View Configuration

3. Scroll to 2022 for example

4. Press Today button - app crashes

It is easily reproducuble.

Here is the log from logcat:

The chart's series are not detecting property changed notifications on items in the series.

Note:

  • This works as expected in UWP
  • The series also doesn't seem to detect any ItemsSource property changes either.

Reproducible

If you have a data model where the properties are using INotifyPropertyChanged, for example from your NotifyPropertyChangedBase

public class Item : NotifyPropertyChangedBase
{
    private DateTime date;
    private int value;

    public DateTime Date
    {
        get => date;
        set => UpdateValue(ref date, value);
    }

    public int Value
    {
        get => value;
        set => UpdateValue(ref this.value, value);
    }
}

Here's a view model to use, invoke the command to observe the problem

public class MainViewModel : NotifyPropertyChangedBase
{
    public MainViewModel()
    {
        var rand = new Random();

        DataPoints = new ObservableCollection<Item>(Enumerable.Range(1,5).Select(i=>new Item
        {
            Date = DateTime.Today.AddDays(-i),
            Value = rand.Next(1,10)
        }));

        ChangeDataCommand = new Command(() =>
        {
            foreach (var dataPoint in DataPoints)
            {
                dataPoint.Value = rand.Next(1, 20);
            }
        });
    }

    private ObservableCollection<Item> dataPoints;
    public ObservableCollection<Item> DataPoints
    {
        get => dataPoints;
        set => UpdateValue(ref dataPoints, value);
    }

    public Command ChangeDataCommand { get; set; }
}

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>

    <telerikChart:RadCartesianChart x:Name="Chart">

RdBusyIndicator BusyContent data binding does not work. If a string constant is assigned to the     

 

     <telerik:RadBusyIndicator
                HorizontalOptions="FillAndExpand"
                VerticalOptions="FillAndExpand"
                IsBusy="{Binding IsBusy}"
                IsVisible="{Binding IsBusy}"
                AnimationContentHeightRequest="60"
                AnimationContentWidthRequest="60"
                AnimationType="Animation3"
                AnimationContentColor="{DynamicResource BrandPrimaryColor}">
                <telerik:RadBusyIndicator.BusyContent>
                    <Label Text="{Binding BusyContent}" HorizontalOptions="Center"/>
                </telerik:RadBusyIndicator.BusyContent>
      </telerik:RadBusyIndicator>

 

RdBusyIndicator BusyContent data binding does not work for the above Label inside the "telerik:RadBusyIndicator.BusyContent". If a string constant is assigned to the Text(for example "Loading..."), then it works perfectly.

The view model 100% has the property "BusyContent" with a value. By the way, the IsBusy and IsVisible data binding work fine.

Use the following code to reproduce the behavior described in the issue title:

<telerikInput:RadButton BorderThickness="10,0,0,0" BorderColor="Blue" Clicked="RadButton_Clicked"/>

private void RadButton_Clicked(object sender, EventArgs e)
{
  RadButton btn = (RadButton)sender;
  if (btn.BorderColor == Color.Blue)
  {
    btn.BackgroundColor = Color.Yellow;
    btn.BorderColor = Color.Red;
  }
  else
  {
    btn.BorderColor = Color.Blue;
    btn.BackgroundColor = Color.Cyan;
  }
}

Expected Result:

Both the BackgroundColor and BorderColor change without any changes to BorderThickness.

Observed Result:

The RadButton's border disappears. Note that even if I programmatically set BorderThickness in the same click event, it is still not visible again.

 

This is reproducible using 2020.1.318 and minimum required dependencies on Android.

In the SearchViewSingleLineItems Telerik template, it places a RadListView in an auto-sized RowDefinition. As a result, this causes the RadListView not to appear on iOS. This should be a star-sized row as mentioned in this UI for Xamarin documentation.

Although unrelated to the issue, the deprecated RadAutoComplete is being used for the example. Please update it to use the new RadAutoCompleteView instead.

Please update this template (and any other search templates that might have the same issues), thank you.

I have upgraded my Xamarin.Forms to version 4.5 and installed the dependent AndroidX nuget packages.  After upgrading UI for Xamarin to version 2020.1.318.1, I'm getting 3 errors below in my Xamarin Android project that seems to have to do with min SDK version when I try to build:

java/lang/String;Ljava/util/List;)[B :  invalid opcode ba - invokedynamic requires --min-sdk-version >= 26 (currently 13)

I'm targeting Android 9 and set the minimum supported SDK to 26.  The error hasn't gone away.

I upgraded to latest Telerik to address a reference issue with AndroidX.RecyclerView but it seems that these new errors are showing up now. 

Is there something I can do to resolve the error or do I just have to wait for the next Telerik UI for Xamarin release?

If you have a project that has a dependency on: Xamarin.AndroidX.RecyclerView

It will cause a Release build failure due to Telerik.XamarinForms.DataControls using the wrong type in the renderer (AndroidX's RecyclerView instead of v7.Widgets's RecyclerView).

Here is the build error clarifying that it cannot find a `HasStableIds` property/method:

Error Mono.Linker.MarkException: Error processing method: 'System.Void Telerik.XamarinForms.DataControlsRenderer.Android.ItemsControlRenderer::OnElementAttached(Telerik.XamarinForms.DataControls.ItemsControl)' in assembly: 'Telerik.XamarinForms.DataControls.dll' ---> Mono.Cecil.ResolutionException: Failed to resolve System.Void AndroidX.RecyclerView.Widget.RecyclerView/Adapter::set_HasStableIds(System.Boolean)

Reproduce

You can use the attached project to reproduce the problem. Be sure to have the following settings:

  • Build in Release configuration
  • Set LinkerBehavior to SDK assemblies Only

Workaround

Uninstall Xamarin.AndroidX.RecyclerView

When using the __ItemStyle properties of RadListView, they are not being applied if the SelectionMode is set to None. It makes sense that the PressedItemStyle and SelectedItemStyle properties are not used, since they are not applicable if nothing can be selected. However, the ReorderItemStyle in particular should still be used.

 

Example:

    public class ItemStyleNotAppliedExample : ContentPage
    {
        private readonly ListViewItemStyle WhiteBG = new ListViewItemStyle
        {
            BackgroundColor = Color.White
        };

        private readonly ListViewItemStyle YellowBG = new ListViewItemStyle
        {
            BackgroundColor = Color.Yellow
        };

        private readonly ListViewItemStyle RedBG = new ListViewItemStyle
        {
            BackgroundColor = Color.Red
        };

        private readonly ListViewItemStyle BlueBG = new ListViewItemStyle
        {
            BackgroundColor = Color.Blue
        };

        public ItemStyleNotAppliedExample()
        {
            BackgroundColor = Color.Gray;

            var items = new ObservableCollection<Item>
            {
                new Item("Item 1"),
                new Item("Item 2"),
                new Item("Item 3"),
                new Item("Item 4"),
                new Item("Item 5"),
            };

            Content = new RadListView
            {
                SelectionMode = SelectionMode.None,
                IsItemsReorderEnabled = true,
                ItemsSource = items,
                ItemTemplate = new DataTemplate(typeof(ItemView)),

                ItemStyle = WhiteBG,
                PressedItemStyle = YellowBG,
                SelectedItemStyle = RedBG,
                ReorderItemStyle = BlueBG,
            };
        }

        private class Item
        {
            public string Name { get; }

            public Item(string name)
            {
                Name = name;
            }
        }

        private class ItemView : ListViewTemplateCell
        {
            public ItemView()
            {
                var checkbox = new CheckBox
                {
                    VerticalOptions = LayoutOptions.Center
                };

                var label = new Label
                {
                    VerticalOptions = LayoutOptions.Center
                };

                label.SetBinding(Label.TextProperty, nameof(Item.Name));

                    Children =

We have yet to upgrade our mobile app to Xamarin Forms 4.x and the latest Telerik releases due to a hard crash in Android when we leave a page containing a Telerik ListView control.   

The exception seems to mirror what is discussed here:  https://www.telerik.com/forums/null-ref-error-iorderedtraversalcontroller-updatetraversalorder

Here is what we are seeing... what is the latest on addressing this error?   We need to upgrade from Xamarin Forms 3.6.x soon.
