Hi Team,

When I use a RadEntry or Entry in the RadListView, it is fine when rendering flat data. However, when the items are grouped, the app has a native WinUI unhandled exception (that needs a 2nd instance of VS2022 to catch).

The only way to stop it was to not use an entry-like control like a Label.

Here is code to reproduce it,  I've attached a runnable example

 

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:telerik="clr-namespace:Telerik.Maui.Controls;assembly=Telerik.Maui.Controls"
             xmlns:telerikDataControls="clr-namespace:Telerik.XamarinForms.DataControls;assembly=Telerik.Maui.Controls.Compatibility"
             xmlns:telerikListView="clr-namespace:Telerik.XamarinForms.DataControls.ListView;assembly=Telerik.Maui.Controls.Compatibility"
             x:Class="EntryTests.MainPage">
    <Grid>
        <telerikDataControls:RadListView x:Name="rulesListView"
                                         ItemsSource="{Binding Clients}"
                                         VerticalScrollBarVisibility="Always">
            <telerikDataControls:RadListView.GroupDescriptors>
                <telerikListView:PropertyGroupDescriptor PropertyName="Username" />
            </telerikDataControls:RadListView.GroupDescriptors>
            <telerikDataControls:RadListView.ItemTemplate>
                <DataTemplate>
                    <telerikListView:ListViewTemplateCell>
                        <!-- WORKS -->
                        <!--<Label Text="{Binding Username}" FontSize="14"/>-->
                        <!-- HARD CRASH -->
                        <telerik:RadEntry Text="{Binding Username}" FontSize="14" />
                    </telerikListView:ListViewTemplateCell>
                </DataTemplate>
            </telerikDataControls:RadListView.ItemTemplate>
        </telerikDataControls:RadListView>
    </Grid>
</ContentPage>

 

Version Note: The repro app is using UI for MAUI v0.9.0 because it was tested by Lance McCarthy with both 0.8.0 and 0.9.0 (this 0.9.0 was built on May 11th).

I used RadListView in a Grid, Grid has ColumnSpacing, 

for example:

 <Grid
RowSpacing="1"
      ColumnSpacing="1"
      WidthRequest="305"
      HeightRequest="303"
      BackgroundColor="#FF454545">
    <Grid.RowDefinitions>
        <RowDefinition Height="36"/>
        <RowDefinition Height="28"/>
        <RowDefinition Height="82"/>
        <RowDefinition Height="50"/>
        <RowDefinition Height="50"/>
        <RowDefinition Height="50"/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="152"/>
        <ColumnDefinition Width="152"/>
    </Grid.ColumnDefinitions>

    <telerik:RadListView x:Name="listView" Grid.Row="5" Grid.ColumnSpan="2" WidthRequest="305">
        <telerik:RadListView.ItemTemplate>
            <DataTemplate>
                <telerik:ListViewTemplateCell>
                    <telerik:ListViewTemplateCell.View>
                        <Grid BackgroundColor="Gray">
                            <Label Margin="10" Text="{Binding Name}" />
                        </Grid>
                    </telerik:ListViewTemplateCell.View>
                </telerik:ListViewTemplateCell>
            </DataTemplate>
        </telerik:RadListView.ItemTemplate>
    </telerik:RadListView>
</Grid>

I found the RadListView.Width is 304(ColumnDefinition plus), not 305.

Release 2.3.0

When using .net maui multi-window and adding RadListView the following exception occurs on some mac machines: 

Terminating app due to uncaught exception 'NSObjectNotAvailableException', reason: 'UIAlertView is deprecated and unavailable for UIScene based applications, please use UIAlertController!'

An example with CollectionView:

<CollectionView ItemsSource="{Binding EmptyMonkeys}"
                EmptyView="No items to display" />
