Description

Defined a RadioButton with an inline content definition.

Instead of displaying the Content, this shows the type name.

Refer to the screenshot for more details.

Steps to Reproduce

1. Create a new .NET MAUI App
2. Add a new Content Page and the below code snippet to simulate the issue
3. Set this newly added page as the Main page
4. Set Android as the target platform, build and then run the project
5. And it works fine in Windows without any issue and unable to check on the other platforms

<?xml version="1.0" encoding="UTF-8" ?>
<ContentPage
    x:Class="Issue6614.TestPage"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:m="clr-namespace:Microsoft.Maui;assembly=Microsoft.Maui"
    Title="TestPage">
    <ContentPage.Resources>
        <ResourceDictionary>
            <m:Thickness x:Key="OptionPadding">3,0,0,0</m:Thickness>
        </ResourceDictionary>
    </ContentPage.Resources>
    <StackLayout
        HorizontalOptions="Center"
        RadioButtonGroup.GroupName="AppTheme"
        VerticalOptions="Center">
        <RadioButton IsChecked="{Binding UseSystem}" Value="system">
            <RadioButton.Content>
                <Label Padding="{StaticResource OptionPadding}" Text="Use System" />
            </RadioButton.Content>
        </RadioButton>
        <RadioButton IsChecked="{Binding LightTheme}" Value="light">
            <RadioButton.Content>
                <Label Padding="{StaticResource OptionPadding}" Text="Light" />
            </RadioButton.Content>
        </RadioButton>
        <RadioButton IsChecked="{Binding DarkTheme}" Value="dark">
            <RadioButton.Content>
                <Label Padding="{StaticResource OptionPadding}" Text="Dark" />
            </RadioButton.Content>
        </RadioButton>
    </StackLayout>
</ContentPage>

Version with bug

Release Candidate 2 (current)

Last version that worked well

Release Candidate 1

Android, I was not able test on other platforms

Did you find any workaround?

Have to set the value to the Content directly instead of using the extended Content definition.

Relevant log output

NA

Attached is the project to simulate the issue.

I'm wondering if this is the cause: https://github.com/dotnet/maui/blob/main/src/Controls/src/Core/RadioButton.cs#L563

Do you see anything like that in the logging @egvijayanand?

Not adding the needs-info tag as it seems an obvious bug we can work on. Just trying to get more information without actually debugging it (yet)

@jfversluis Let me try again to check if anything is getting logged.

@jfversluis Here's the Debug log.

Hope it helps. Since I don't see any phrase that is mentioned in the link shared. Let me know if it's getting logged somewhere else.

Verified this issue with Visual Studio Enterprise 17.3.0 Preview 1.0 [32427.455.main]. Repro on Android with above Issue6614.zip project.

Any update on this? I'm also having this issue.

Right.

Will check and update.

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. To learn more about our issue management process and to have better expectation regarding different types of issues you can read our Triage Process.

This is the expected behavior for a RadioButton on Android; the Android platform doesn't support arbitrary in-line content: https://learn.microsoft.com/en-us/dotnet/maui/user-interface/controls/radiobutton?view=net-maui-7.0#display-arbitrary-content

To display arbitrary content on Android, you'll need to set a ControlTemplate for the RadioButton: https://learn.microsoft.com/en-us/dotnet/maui/user-interface/controls/radiobutton?view=net-maui-7.0#redefine-radiobutton-appearance
