The exception is easily reproducible in SDK Browser on iOS. Start the LoadOnDemandCommand or LoadOnDemandEvent example to see the exception. The LoadOnDemandCollection seems to work correctly, however.

The ListViewLoadOnDemandCollection can be used instead of the command/event as a temporary workaround, until the bug gets fixed.

I'd been testing the trial version of the Telerik chart control for Xamarin in an Android app. Because it was working well, I'd purchased a license yesterday. And, I replaced the NuGet trial package with the license package. So far, so good.

However, now, when I try to build the project, it fails. (I've tried building both the Release and Debug version.)

The errors I see are below:

Severity Code Description Project File Line Suppression State
Error failed linking references. Ble.Client.Android
Error resource style/MainTheme.Base (aka com.companyname.ble.client:style/MainTheme.Base) not found. Ble.Client.Android
ErrorNU1301       Failed to retrieve information about 'Xamarin.AndroidX.AppCompat' from remote source 'https://packagesource/FindPackagesById()?id='Xamarin.AndroidX.AppCompat'&semVerLevel=2.0.0'. Ble.Client.Android D:\2023_devwork\BLE_Xamarin\XamarinBleCodeBehind-main\XamarinBleCodeBehind-main\Ble.Client\Ble.Client.Android\Ble.Client.Android.csproj 1

Any thoughts as to what might have broken, and, what I need to do in order to resolve the issue? (In case it helps, I'm including a screen capture of the Visual Studio 2022 output window.)

The scrollbar on UWP is blocking the content (including the options button which is also not clickable because of it

Workaround: Add a style for the column header and apply margin to the Options button:


            <telerikGrid:DataGridColumnHeaderStyle x:Key="headerstyle"
                                           TextColor="Black" OptionsButtonMargin="0,0,20,0" 
        <telerikGrid:RadDataGrid ItemsSource="{Binding Items}" BackgroundColor="Red" AutoGenerateColumns="false">
                <telerikGrid:DataGridTextColumn PropertyName="Country" HeaderStyle="{StaticResource headerstyle}"/>
                <telerikGrid:DataGridTextColumn PropertyName="Capital" HeaderStyle="{StaticResource headerstyle}"/>

In my item tapped command I find the tapped object in the bound list, and set one of its flags. The problem occurs when the set triggers the OnPropertyChanged event of one of those flags, and then the app crashes.

When you have a DataGrid with a lot of items, if you scroll down the list then leave that page and come back, the list does not appear until you scroll down.  As soon as you scroll down the list repaints and the items show as expected.

I am trying to show two LineSeries with 11500 points in each and the chart cannot load at all. The wait time seems to be infinite. I noticed that the chart loads in about 5 seconds when there 5 thousand points, and in about 10 seconds when there are 10 thousand points.

Steps to reproduce

- add this code to the end of page constructor:

 var tabItem = new TabViewItem()
     Header = new TabViewHeaderItem { Text = "Prague" },
     Content = new StackLayout
         Children =
             new Label {Text = "Prague"}
 var index = tabView.Items.Count - 2;
 tabView.Items.Insert(index, tabItem);
The content for Prague header is the content from different tab.

appointments show wrong time in different time zones due to daylight time changes.

The issue can be reproduced in scenarios:

- For US time zone 14th of march: If I click an empty slot, I have a popup that tells the time that is clicked. I click on the 9 AM slot and it says I'm clicking on "10:00". This only happens on 3/14/2021

- For European countries time zone: on 28th or march 2021 when is the daylight saving time

I don't know how to describe it other than what  I put in the subject, but the list view jumps back to the top when more items are added to the ObservableCollection. Either that or a MonoTouchException gets thrown.

When you zoom in on the graph, it always zooms to the center of the dataset. Even if I try to move, manually, horizontally the graph I lose the position when a point is added.

When point is added and chart is zoomed, cannot scroll to see other data, the chart reset the data visualization from the beginning.

Some Image XObjects are imported but not displayed in PdfViewer.  This behavior usually occurs when the document contains scanned images.

Giving a RadDataGrid where columns are mostly empty, scroll to the right and mutate the data. All the rows without data visible disappear until the user scrolls back to columns that have data.

Sample project attached.
