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.
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" />
