maui: CollectionView does not select an element with a Frame as DataTemplate

Description

When you have a selection mode other than None, and a DataTemplate with a Frame, it is not possible to select one of the elements by clicking on the content of the frame, only outside the Frame control.

Steps to Reproduce

1.- Create a new .NET MAUI project. 2.- Remove default content. 3.- In the XAML file:

<CollectionView SelectionMode="Single">
        <CollectionView.ItemsSource>
            <x:Array Type="{x:Type x:String}">
                <x:String>mono</x:String>
                <x:String>monodroid</x:String>
                <x:String>monotouch</x:String>
                <x:String>monorail</x:String>
                <x:String>monodevelop</x:String>
                <x:String>monotone</x:String>
                <x:String>monopoly</x:String>
                <x:String>monomodal</x:String>
                <x:String>mononucleosis</x:String>
            </x:Array>
        </CollectionView.ItemsSource>
        <CollectionView.ItemTemplate>
            <DataTemplate>
                <Frame Margin="5">
                    <Label Text="{Binding .}" />
                </Frame>
            </DataTemplate>
        </CollectionView.ItemTemplate>
    </CollectionView>

Test the application. 5.- Try to select an element, and see that it is only possible to do it by clicking outside the Frame border. fCiICq9iDO

The workaround for this is to use Border. Perhaps MSFT should add the [Obsolete] attribute so that future developers are aware about this issue? Thanks to @myrup for this workaround.

This issue hasn’t seen any progress. If Frame is deprecated (MSDN documentation mentions it is), it should be clearly identified as such in the code with the [Obsolete] attribute with a message stating to only use in older Xamarin applications, and referencing Border as the preferred control.

I just spent the morning trying to determine why a simple command wasn’t firing when tapping on the content. I accidentally clicked in the corner region and realized it was the Frame content which brought me here. This is a pretty big waste of time for a known bug related to a core component of the .NET MAUI framework.

Frame is apparently there for legacy reasons. Consider using Border instead (untested).

Using Border worked for android. But not working on Mac. Is there any workaround for mac? –Update I tried again, I found out that i have hold the click for atleast 3 seconds in order to change the selection.

We’ve moved this issue to the Backlog milestone. This means that it is not going to be worked on for the coming release. We will reassess the backlog following the current release and consider this item at that time.
