ContentPresenter.Content is not inheriting its content

[samoteph]

If I try to redefine the template of a button like this the contentpresenter doesn't work. But with ContentControl it's working !

<Style x:Name="EmptyButtonStyle" TargetType="Button">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <ContentControl Content="{TemplateBinding Content}"/>
                <!--<ContentPresenter></ContentPresenter>-->
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

@samoteph it depends on thye platform. On iOS and Android, for now, the default style on Uno is using the native controls (e.g. BindableUIButton on iOS), which do not support advanced content. Also, defining an empty named or keyed style does not override the platform's default style, it merges its setters with the platform's style.

If you want to create your own button template, take the UWP generic.xaml (C:\Program Files (x86)\Windows Kits\10\DesignTime\CommonConfiguration\Neutral\UAP\10.0.14393.0\Generic\generic.xaml) default button template and customize from there, with a Template setter defined.

Let us know if this fixes your problem!

Thanks for the explanation about the button but in this case I don't understand why ContentControl works and ContentPresenter doesn't

Make more sense with your updated sample. Yes, we do have one issue with the application of the content property of the ContentPresenter, you have to specify Content="{TemplateBinding Content}" on the ContentPresenter as the property is not yet inherited in Uno.

My bad ! A problem of git tag to see the complete sample :)
