I am in the process of preparing my product for alpha release and I am scrubbing my log files for anything that needs to be cleaned up prior to release. I am seeing two message in my log file that I cannot pinpoint in my code so I am suspecting it is coming from your code. I use NLog to log errors so I format Errors differently than general errors. I am seeing the following two errors being logged on app startup:

----------------------------------

In my MauiProgram.cd file, I load many fonts:

		_ = builder
			.UseMauiApp<App> ()
			.UseTelerik ()
			.ConfigureFonts (fonts => {
				_ = fonts.AddFont ("FontAwesome6Brands-Regular-400.otf", "FaBrands");
				_ = fonts.AddFont ("FontAwesome6Duotone-Solid-900.otf", "FaDuotone");
				_ = fonts.AddFont ("FontAwesome6Pro-Light-300.otf", "FaLight");
				_ = fonts.AddFont ("FontAwesome6Pro-Regular-400.otf", "FaRegular");
				_ = fonts.AddFont ("FontAwesome6Pro-Solid-900.otf", "FaSolid");
				_ = fonts.AddFont ("FontAwesome6Pro-Thin-100.otf", "FaThin");
				_ = fonts.AddFont ("OpenSans-Regular.ttf", "OpenSansRegular");
				_ = fonts.AddFont ("OpenSans-Semibold.ttf", "OpenSansSemibold");
				_ = fonts.AddFont ("Poppins-Black.otf", "PoppinsBlack");
				_ = fonts.AddFont ("Poppins-BlackItalic.otf", "PoppinsBlackItalic");
				_ = fonts.AddFont ("Poppins-Bold.otf", "PoppinsBold");
				_ = fonts.AddFont ("Poppins-BoldItalic.otf", "PoppinsBoldItalic");
				_ = fonts.AddFont ("Poppins-ExtraBold.otf", "PoppinsExtraBold");
				_ = fonts.AddFont ("Poppins-ExtraBoldItalic.otf", "PoppinsExtraBoldItalic");
				_ = fonts.AddFont ("Poppins-ExtraLight.otf", "PoppinsExtraLight");
				_ = fonts.AddFont ("Poppins-ExtraLightItalic.otf", "PoppinsExtraLightItalic");
				_ = fonts.AddFont ("Poppins-Italic.otf", "PoppinsItalic");
				_ = fonts.AddFont ("Poppins-Light.otf", "PoppinsLight");
				_ = fonts.AddFont ("Poppins-LightItalic.otf", "PoppinsLightItalic");
				_ = fonts.AddFont ("Poppins-Medium.otf", "PoppinsMedium");
				_ = fonts.AddFont ("Poppins-MediumItalic.otf", "PoppinsMediumItalic");
				_ = fonts.AddFont ("Poppins-Regular.otf", "PoppinsRegular");
				_ = fonts.AddFont ("Poppins-SemiBold.otf", "PoppinsSemiBold");
				_ = fonts.AddFont ("Poppins-SemiBoldItalic.otf", "PoppinsSemiBoldItalic");
				_ = fonts.AddFont ("Poppins-Thin.otf", "PoppinsThin");
				_ = fonts.AddFont ("Poppins-ThinItalic.otf", "PoppinsThinItalic");
				_ = fonts.AddFont ("Segoe-Ui.ttf", "SegoeUi");
				_ = fonts.AddFont ("Segoe-Ui-Bold.ttf", "SegoeUiBold");
				_ = fonts.AddFont ("Segoe-Ui-Regular.ttf", "SegoeUiRegular");
				_ = fonts.AddFont ("Segoe-Ui-Semibold.ttf", "SegoeUiSemibold");
				_ = fonts.AddFont ("Segoe-Ui-Semilight.ttf", "SegoeUiSemilight");
			})
			.ConfigureMobyApplication ();

As you can see, 'Assets/Fonts/Segoe UI.ttf' or 'Assets/Fonts/Segoe UI.otf' is a font I am loading. In fact, all of the 'Segoe' font names use a dash '-' instead of a space in the file name. Also, I only load 'ttf' fonts and not 'otf' fonts for Seqoe fonts. Telerik controls are the only non-standard controls I am using so I am suspecting this font name is being loaded by your controls somehow. Can you please confirm this?

Also, when I went to report this incident, I noticed that you had requested input from me on previous issues I have raised, but I never received any email from you requesting this information. Since I rarely log into this website for anything, I don't know how you expect people to answer your questions if they are not made more visible. Is there a way to subscribe to an issue so I see all updates? I looked over the complete set of items I can add to this issue and none of them seem to be related to answering questions from you. It would be helpful for you to send any and all updates on any issues that have been logged. I just scanned my entire set of email folders and other than messages from your sales department, no other messages were found. Just sayin'...

Asking for a webview which opens external links ( links with a target= element) in the same webview instead of it does do nothing onbios and android, but in windows opens it a browser window with that url of the link!

we need the functionality to overrule the target= function of a link. To the same webview. At this moment we need a hybridwebview functionality! And it would be very handy to have that in a telerik control!

I'm forced to use RadNumericInput with styling the NumericInputEntry HorizontalTextAlignment set to End

<Style x:Key="rightNumericInputEntryStyle"
       TargetType="telerik:NumericInputEntry">
    <Setter Property="HorizontalTextAlignment" Value="End" />
</Style>
...
<telerik:RadNumericInput AutomationId="ageNumeric"
                         EntryStyle="{StaticResource rightNumericInputEntryStyle}"
                         Minimum="0" 
                         Value="{Binding Age, Mode=TwoWay}" />

doing this, the value is cut off, when the controls width gets small.
There is some space on the left, which is not used.

Easy to reproduce in the SDK Samples.
I'm not able to find a way changing this

Value in this Screenshot: 123456, cut after 5

any workaround (keeping the value HorizontalTextAlignment="End")  is highly appreciated

I tested streaming data for nested property and the UI does not update. The data is updated in the collection bound to the DataGrid ItemsSource, still the UI doesn't. 

When I enter editing the cell, the UI updates.

The issue happens in this case:

                <telerik:DataGridNumericalColumn PropertyName="Address.Age"
                                            HeaderText="Age" />

                <telerik:DataGridTextColumn DataMemberBinding="{Binding Address.Age}"
                             HeaderText="Age DataMemberBinding"/>

If this worked in earlier releases, it no longer does.

Using iOS Simulator (set to iPhone 15 iOS 17.4) - with a DataGrid as below, double-clicking the text cell will crash the app. I have not yet tried on a native device build (not simulator.)

<telerik:RadDataGrid.Columns>
    <telerik:DataGridTextColumn PropertyName="ObjectName" HeaderText="Name"/>
</telerik:RadDataGrid.Columns>

Data Form Editors expose the property EditorStyle to allow setting the input control's overall style. But some input control have multiple styles not so easily set.

As the input control is also the Editor's base content, instead exposing content as the appropriate type allows all of the input controls styles to be set.

Here is my working example in my KingdomContacts app for one editor:

namespace KingdomContacts.Controls;
using Telerik.Maui.Controls;
public class KcNumericDfEditor : DataFormRadNumericEditor
{
    public RadNumericInput? Editor => base.Content as RadNumericInput;
}

I have made similar adaptations for all the other Data Form editors I use. Simple and easy to work with; far easier than guessing what to do with EditorStyle.

Would be even easier if a similar line were inside your editors -- then I would not need to make my own customizations.

When I compile my project with <WindowsPackageType>None</WindowsPackageType> option, icons ar enot displayed in Telerik controls (like richeditor)

Same project compiled with package  and deployed are ok

During data binding, the busy indicator freezes.  This is not a problem with the MAUI ActivityIndicator, however. See the attached video

I created a repo here to reproduce the issue: https://github.com/kklose23/busyindicator-freezing

Note:  I know there's ways to make the data binding in that repo more efficient.  I just wanted a good example.

When the Source of a RadRichTextEditor is set, the TextColor is always black.  Tested on Android:

  <Grid HeightRequest="400"
        WidthRequest="300">
    <telerik:RadRichTextEditor x:Name="RichTextEditorControl"
                               Source="with source text"
                               TextColor="White"
                               BackgroundColor="Green" />
  </Grid>

I have an html file with <img src="./images/ForkliftGateMainPage.png" alt="MainPage" width="1600" title="Page principale" />

The image is displayed when I open it with my browser, but not displayed with RadRichtextEditor, Why ?

When updating to .net8 the following snippet doesn't work with target net8 (maui 8.0.3). Same works with net7 (up to 7.101).
Stops me from targeting net8.

<telerik:RadListView.FooterTemplate>
    <DataTemplate>
        <Grid
            BackgroundColor="{AppThemeBinding Dark={StaticResource ListElementColorDark},
                                              Light={StaticResource ListElementColorLight}}"
            IsVisible="{Binding CanSearchMore}">
            <telerik:RadBorder Padding="8,10" Style="{StaticResource ListItemContainer}">
                <Label HorizontalOptions="Start" Text="{Binding SearchMoreText}" />
            </telerik:RadBorder>
            <Grid.GestureRecognizers>
                <TapGestureRecognizer Command="{Binding SearchMoreCommand}" />
            </Grid.GestureRecognizers>
        </Grid>
    </DataTemplate>
</telerik:RadListView.FooterTemplate>

1. TapGestureRecognizer: Command is not executed / Click not detected
2. Style: Having a PointerOver in "ListItemContainer" works with net7. Doesn't work with net8

Repro steps:

Put a grid inside a RadBusyIndicator with a button.  On a button click, set IsBusy to true, change the height of the grid, and set IsBusy to false.  The grid height will not be updated.

Another way to reproduce is to add children views to the grid while IsBusy is true.  The children will not be rendered after it's done

This is a regression from a recent Telerik update
