The "Scrolled" event is such a essential feature.

For example, i made a floating searchbar with transparent frame, and a RadListView with HeaderTemplate that is longer than a screen of the device, i would like to detect whether the listview has scrolled for more than 10px vertically. If yes, set the background of the frame of the searchbar to my desired color.Xamarin.Forms, collectionview, listview, and scrollview has Scrolled event, but why RadListView does not? Using ItemAppearing event is just avoiding the problem instead of solving it. It will not be able to fulfill the criteria as the any item does not even enter the screen yet before the required task need to be done.

We are only using the Rad ListView, so have only needed the Lite package but it requires the SkiaSharp package as well. It seems that Map, ImageEditor, PdfViewer and DataGrid controls are added in the lite nuget package.

Above the TreeView there is a Telerik.SegmentedControl, with two segments. If I click on one of the segments the ItemsSource of the TreeView gets updated by using .Add() or Remove() of the ObservableCollection.

If every Segment is called for the first time there is no problem. But if I want to clear all Items and display the empty treeView I get the following Exception.
Java.Lang.IndexOutOfBoundsException: 'Inconsistency detected. Invalid item position 0(offset:-1).state:14 md5a5af569a83c1a3f5c3a8a63bd7d39860.RadExtendedListView{c6376f1 VFED..... ........ 0,0-1200,840 #5}, adapter:com.telerik.widget.list.ListViewWrapperAdapter@b30041b, layout:android.support.v7.widget.LinearLayoutManager@3fd42d6, context:md5db22775bb305bf9756607f4261793d51.MainActivity@1d6cd4f

The bug can be reproduced on iOS 13 only. It is not reproducible on earlier versions of iOS. Run the attached project on iOS 13 device or Simulator to reproduce it.

Sometimes when focusing an entry and the onscreen keyboard shows up, the ListView is not scrolled correctly, so the entry is overlapped by the keyboard. The ListView layout appears messed up after that and the scrolling does not behave correctly.

Refer to the attached reproducible.

1. Run app and apply a filter: "Contains 0"

2. Notice #40 is in the correct location, between #30 and #50

3. Press the button on the bottom of the page to go BlankPage and then navigate back.

4. Observe #40 is now at the end of the rows even though the filter is clearly applied.

Look in MainPageViewModel.cs lines 42 to 49. When the navigation back occurs, this code is executed.  I can reproduce the problem with both Replace and Add+Remove operations.

public override void OnNavigatedTo(INavigationParameters parameters)
{
    base.OnNavigatedTo(parameters);

    if (!parameters.ContainsKey("from"))
    {
        var items = new ObservableCollection<MyModel>();
        for (var i = 1; i <= 100; i++)
            items.Add(new MyModel { Number = i.ToString() });
        Items = items;
    }
    else
    {
        var item = Items[39];

        // Bug Test #1 - using ObservableCollection Reset
        Items[39] = item;

        // Bug Test #2 - using ObservableCollection Remove & Add
        //Items.RemoveAt(39);
        //Items.Insert(39, item);
    }
}

When longer string is used for HeaderText the text could not be wrapped. Also the issue occurs when using Label with LineBreakMode="WordWrap" inside the TabViewHeaderItem.Content:

<telerikPrimitives:TabViewItem>
    <telerikPrimitives:TabViewItem.Header>
        <telerikPrimitives:TabViewHeaderItem>
            <telerikPrimitives:TabViewHeaderItem.Content>
                <Label Text="Lorem ipsum dolor sit amet, consectetur adttert etertert erterter ipiscing elit." LineBreakMode="WordWrap"/>
            </telerikPrimitives:TabViewHeaderItem.Content>

As of the latest release (10/04/2019) RadPieChart with a PieSeries having LabelBinding set to a property name, and ShowLabels set to True, with the list of data bound to ItemsSource containing one or more empty pie slices (a null in the list), causes a System.Reflection.TargetException to be thrown on load of the page containing the chart in iOS (this scenario works fine in UWP).

I am using the latest available Visual Studio 2019 (16.3.5) and the latest available Xamarin.Forms package (4.2.0.848062) and testing on an iPad with iOS 13.1.  The reason I need to have a null value in the list is so that the custom color palette I'm applying will always apply the same colors to the same data points (pie slices), even though in some cases, zero or one or two of the three pie slices will have no data value (and so should not appear in the chart, but still "use up" the corresponding color in the 3 colors of the palette).

In the 08/02/2019 release, this scenario worked fine in iOS (the 09/13/2019 release had the https://feedback.telerik.com/xamarin/1431067-chart-ios-invalidcastexception-is-thrown-when-the-chart-is-loaded issue, which is now resolved in the 10/04/2019 release, but which prevented my testing in iOS since in my app I had RadCartesianCharts on the same pages as the RadPieCharts).

The newly broken functionality in iOS could possibly be related to two other items that are marked completed:
https://feedback.telerik.com/xamarin/1366403-piechart-tooltip-behavior-is-not-working-properly (in 10/04/2019 release)
https://feedback.telerik.com/xamarin/1365842-chart-null-value-support (in R3 2018 SP release)

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.

I have a StackLayout, a ListView and within the listview a RadCheckBox and a Label. The StackLayout has a binding to IsVisible with the viewmodel. The ListView binds IsVisible to another property bound in the viewmodel. When OnAppearing of the Page, the ItemsSource of the ListView is set to an ObservableCollection. Now we get a crash on iOS and a Samsung Galayxy S with Android 9:

The remedy after a lot of trial and error was to replace the ListView with the Telerik ListView. Now the App no longer crashes. I hope this helps investigating the issue, since I noticed there are similar requests in the bug reports. 

I'm using: Xamarin Forms 4.2.0.848062, Telerik2019.3.1004.1.

Release 2019.3.1119 (R3 2019 minor release)
When I switch from Multi-day view to Day view it doesn't appear to redraw correctly on UWP. I can switch from Month to Day view and it's fine.

The behaviour I'm seeing is that it doesn't hide the multi-day view appointments and then doesn't correctly draw the day view ones. Please see the screen shot attached.

Column names in column selector are not visible in Android the first time the column selector is shown. This happens only in the case UserFilterMode is disabled.

I've attached a handler to the ViewChanged event of the Calendar component.

The event fires on Android but not on UWP. I've tried changing the view type using the calendar controls and also programatically but the event is not being fired.

Cell height is not being adjusted to show all the content. the text overflow and it overlap the cell below. It seems that dynamic size is not respected.

Hello, 

Another important control is missing from your Control Suit. That is Rich Text Box control, same like one available from SyncFusion: https://www.syncfusion.com/xamarin-ui-controls/xamarin-richtexteditor

Please give us a rich text editor control like that. Thank you.
