I tested Android and iOS only. Other platforms i cannot test at the moment.
Given the following implementation of the Combobox i observ different behaviour if the bound item is a enum or a class.
<telerik:RadComboBox x:Name="a"
ItemsSource="{Binding CloudProviders}"
SelectedItem="{Binding SelectedCloudProvider}"
IsClearButtonVisible="False">
<telerik:RadComboBox.ItemTemplate>
<DataTemplate>
<Grid HeightRequest="40"
Padding="10">
<Label Text="{Binding Title}"
TextColor="{DynamicResource DisabledTextColor}"
FontSize="14" />
</Grid>
</DataTemplate>
</telerik:RadComboBox.ItemTemplate>
<telerik:RadComboBox.SelectedItemTemplate>
<DataTemplate>
<Grid HeightRequest="40"
Padding="10">
<Label Text="{Binding Title}"
TextColor="{DynamicResource DisabledTextColor}"
FontSize="14" />
</Grid>
</DataTemplate>
</telerik:RadComboBox.SelectedItemTemplate>
</telerik:RadComboBox>
If the Itemssource is a Array of a enum type it works as intended.
If the Itemssource is a Array of classes the initial selected display member is not visible. The moment i tap into the closed combobox, the selected member is visible.
The attached screenshots show the page after loading and after touching into the white area(combobox) once.
For Localization and more details, we want to use classes. Is this a bug or do we have a issue in our code here?
Although Maui has SpreadProcessing, it lacks a matching control. For the very different WPF platform you have one I use, and it would be helpful in Maui to display and readily edit class instances with numerous properties. I realize it would be a challenge to fit into mobile screens, but I do hope you will consider it, as I am trying to get all my current WPF features into my Maui work-alike. Thank you.

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...:

Hi,
Do you have on your roadmap to include a Shimmer View / Control as part of your .NET MAUI offerings to tidy up a screen loading indication.
From a UI/UX perspective, a shimmer sits better with our user community rather than a loading indicator.
Thank you,
Shane
Add a VS Item Template for Login screen as in Telerik UI for Xamarin: VIsual Studio Item Templates.
It took me about 2 days, but finally i've reached out a repo out of the real world app, where the iOS RadListView crashes the app.
Start this repo app on a iPhone 15 Simulator:
https://github.com/baaaaif/TelerikListViewCrash
The ListView crashes the app when the cell is quite high and the height of the list and the height of the cell reach a certain (unknown) ratio
This is in the logs right before the crash :
