With this control you are able to create any style of button. This is possible as it acts as a wrapper to your XAML and provides you the events/ commands and properties to bind too.

It's also 100% accessible with each platform seeing/ treating the control as a native button.

The example page, has a bunch of different design to showcase the usage -

How to use it?

Then in the MauiProgram.cs, and the StateButton configuration method -

How to style the button for different states

Simply add a Trigger to any element and bind it to the State property of the button -

<stateButton:StateButton Padding="20,10" BackgroundColor="Red">
    <stateButton:StateButton.StrokeShape>
        <RoundRectangle CornerRadius="10" />
    </stateButton:StateButton.StrokeShape>
    <stateButton:StateButton.Triggers>
        <Trigger TargetType="stateButton:StateButton" Property="State" Value="Pressed">
            <Setter Property="BackgroundColor" Value="Green" />
        </Trigger>
    </stateButton:StateButton.Triggers>

    <Label Text="Test" TextColor="White">
        <Label.Triggers>
            <DataTrigger Binding="{Binding Source={RelativeSource AncestorType={x:Type stateButton:StateButton}}, Path=State}"
                        TargetType="Label"
                        Value="Pressed">
                <Setter Property="TextColor" Value="Blue" />
            </DataTrigger>
        </Label.Triggers>
    </Label>
</stateButton:StateButton>

Accessibility

The control itself is seen as a native button on both platforms, so inherits the same accessbility attributes. So from a screenreader and keyboard POV it is a native button.

There are a few things you can do to improve the accessibility -

  1. Set the SemanticProperties.Description property on the button. Android is smart enough, that if you dont set this property it will try and find a label within the control to read the text from, iOS does not do this, so if you dont set this property, iOS screenreader will just announce that there is a button, but no name or context is given.

  2. Optionally you can also set the SemanticProperties.Hint property. Using this property you can give more context to what the button is for/ will do.
