I would like to draw attention to this at an early stage.
When using MAUI Nightly 8.0.20-nightly.10376, the app crashes immediately upon startup if you set Telerik Popup Settings in the MAUI Styles

See min repro example https://github.com/baaaaif/MauiNightlyCrash

<MauiVersion>8.0.20-nightly.10376</MauiVersion>
<Style TargetType="telerik:RadTimePicker">
    <Setter Property="PopupSettings">
        <Setter.Value>
            <telerik:PickerPopupSettings IsHeaderVisible="False" />
        </Setter.Value>
    </Setter>
</Style>

From the inner Exception...:

NameValueType
InnerException{"Object reference not set to an instance of an object."}System.Exception {System.NullReferenceException}

I noticed there is a Toggle Button available, but the Toggle Switch Button that is available for WPF is not yet available for MAUI.

Please consider adding such button for .NET MAUI suite.

The Bottom Sheet component provides an intuitive way to display additional content to the users. It appears on the bottom of a screen as an overlay and presents users with a choice of actions that they must take.

I have a basic PDF viewer app with a Pdf View Toolbar.  On it I have a PdfViewerNavigateToPageToolbarItem which correctly displays the current page and page count and on the iOS simulator it works fine - I can enter a page number and hit enter (on a physical keyboard) to navigate to a page.  However, when deploying to an actual device (iPhone 16, iOS 18.3) I can't properly use the Entry to navigate to a page.  When I tap the entry field, the numeric keypad is displayed and I can enter a page number however since there is no "enter" or "done" button on the keypad there's no way to "accept" the value that has been entered so I cannot navigate to a page and there's no way to dismiss the keypad.

I reported a couple of other issues with the Pdf Viewer toolbar items a couple of weeks ago that turned out to be bugs, presumably this is too, but if I am doing something wrong or there is a workaround please let me know.

Thanks

In our MAUI application for iOS, we are using the RadTabView view control and within that we have 3 TabViewItems. Within each of the views associated with the TabViewItems there are various controls including a CollectionView. If we interact with any control within the view, with the exception of the CollectionView, and then we click a tab to move to the next tabbed view everything works as expected. However, if we scroll the CollectionView and then click the tab to navigate to the next tabbed view it does not navigate to the next tab and it's view. Please note that we can still swipe to move from tabbed screen to tabbed screen. That being said, our users do not use the application in that manner so we really need to be able to navigate by clicking the tabs. We are on .NET 9.0.200, iOS workload 18.1.9163/9.0.100, iOS 18.3.1, Telerik 7.0.0, and MAUI controls 9.0.30. I've also attempted to update to the latest stable version of Telerik, 10.0.0, and we had the same issue. Is there a way that we can work around this issue currently or is this an issue that you will soon be releasing a fix for? Thanks.

When adding Telerik controls on the page and run the app on android, the following error message occurs runtime:

Java.Lang.RuntimeException stack trace ---
java.lang.RuntimeException: Font asset not found /data/user/0/com.companyname.appname/cache/telerikfont.ttf
	at android.graphics.Typeface.createFromAsset(Typeface.java:1061)
............

This error message does not prevent the app from working as expected, but the log is full of this message.

When creating a .NET MAUI blank net 9 template and adding for example PDF toolbar, the toolbar icons do not display as the app is build as unpackaged.

Solution:

Change the package type in the .csproj file:

from: 
<WindowsPackageType>None</WindowsPackageType>

Dear Telerik-Team

with the new version 9.0.0 on Android the Scheduler doesn't display the Date/Timepicker on creating/editing an new appointment. The Date/Timepicker Popup is only displayed when the "EditAppointmentDialog" is closed. You can easy reproduce it. Just add the Scheduler to a plain project.

I have attached a VS solution where you can reproduce it.

Thanks for helping/fixing it as soon as possible. I need this new version becasue of another bugfix for scheduler in it...

Probably the same as https://feedback.telerik.com/maui/1662148-popup-maccatalyst-the-popup-is-displayed-on-the-wrong-window-in-case-multiple-windows-are-open-and-the-window-the-popup-is-shown-from-is-not-currently-focused, but for iOS
If you have a ComboBox or Datepicker control in a new UIWindow, the dropdown or picker popup is not displayed.

You can see this, for example, if you use the widely used Mopup popup and display a datepicker in a popup under iOS.
Mopup uses a new UIWindow to display a popup on iOS (https://github.com/LuckyDucko/Mopups/blob/66f585d8c6ccce90a711400b0d14ea378fdb3e5d/Mopups/Mopups.Maui/Platforms/iOS/iOSMopups.cs#L17)

When using Telerik controls, I got the following warning:

 Not linking with the framework OpenGLES referenced by a module reference in SkiaSharp.Views.iOS.dll

when I add a SkiaSharp 3.116.1 version to the project, the warning disappear.

Please update the SkiaSharp package reference in the Telerik MAUI NuGet package

Release 2025 Q1

After updating our Maui application to Maui version 8.0.90, the Entry controls in the WinUI version stopped responding to WidthRequest, HorizontalOptions, or parent container sizes. I thought it was just a Maui problem, but in the relevant issue's notes, I saw that users were having trouble duplicating it unless Telerik UI for .NET Maui was installed (https://github.com/dotnet/maui/issues/24783).

So I created a test app that contains a few Entry controls in various containers:

<?xml version="1.0" encoding="utf-8"?>

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="WinUIEntryBug.MainPage">

    <ScrollView>
        <VerticalStackLayout
            Padding="30,0"
            Spacing="25">

            <Border>
                <Entry />
            </Border>

            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*" />
                </Grid.ColumnDefinitions>

                <Entry Grid.Column="0"></Entry>
            </Grid>

            <Frame>
                <Entry />
            </Frame>

            <Entry />
        </VerticalStackLayout>
    </ScrollView>

</ContentPage>

Without the Telerik components added to the project, the Entry boxes render correctly:

But, when I add a reference to Telerik UI for .NET Maui version 7.1.0 (latest at the time this was written), I get this:

Note: I didn't even add UseTelerik() to the Builder in the MauiProgram.cs, just added the Nuget package.

Changing the WidthRequest, HorizontalOptions, MinWidthRequest, etc. does not affect their size. They do render correctly in iOS and Android, though.

If I then remove the UI for .NET Maui Nuget package, they go back to working.

In our main application, we are heavily dependent on Telerik components and have a substantial number of customers using the Windows version of our application, so this heavily impacts our ability to ship. Particularly since the Maui 8.0.90 fixes other bugs that we needed addressed.

I've attached my sample project with the Telerik UI for .NET Maui package installed. You can remove it to see the normal operation of the Entry boxes.

Release 9.0.0

"System.IO.FileNotFoundException: 'Could not load file or assembly 'Microsoft.Maui.Controls.Compatibility, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.'"

Occurs when creating a blank .net maui project using .net9 and adding Telerik MAUI NuGet Package latest version 8.0.0

Repro steps:

1. Create a new dotnet9 basic project in visual studio.
2. Launch it on windows. it runs.
3. Add the Telerik.UI.for.Maui.Trial package, version 8. (don't bother adding the UseTelerik line to MauiProgram.cs, it'll fail either way).
4. Clean and Rebuild the solution.
5. Debug the app on windows again. It fails on launch with a file not found error that seems to relate to:
"Exception thrown: 'System.IO.FileNotFoundException' in Telerik.Maui.Controls.Compatibility.dll"
System.IO.FileNotFoundException: 'Could not load file or assembly 'Microsoft.Maui.Controls.Compatibility, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.'

Currently Telerik MAUI controls doesn't seem to support Light and Dark Themes(Modes). It will be really helpful to have this feature built in the controls or through styles supported by those controls so that these controls blend in nicely with the Light and Dark Themes supported by the app.
