J'essaie de créer un bouton rond, avec une bordure blanche et un fond transparent (comme l'ancien AppBarButtons dans Windows 8.1) dans UWP Windows 10.
J'ai trouvé plusieurs échantillons comme ceux-ci:
https://comentsys.wordpress.com/2015/05/23/windows-10-universal-windows-platform-custom-button/
Mais le problème vient de la bordure… .. Lorsque je règle le pinceau Border sur une certaine couleur, il s’avère que la bordure est pour le «rectangle» de Button.
Est-il possible de créer une bordure ronde pour un bouton?
Il y a peu de façons d'y parvenir, l'une en utilisant un style peut ressembler à ceci - remove BorderBrush from ContentPresenter et ajoutez un Ellipse avec cette brosse. Échantillon en XAML:

J'ai également apporté des modifications à VisualStates afin que cela ne paraisse pas bizarre une fois que vous avez cliqué/désactivé.
Cherchez-vous quelque chose comme ça?
<StackPanel>
<Button Background="Transparent">
<StackPanel>
<Border CornerRadius="10"
Background="Transparent"
BorderBrush="White"

Ou créez un cornerradius entièrement personnalisable

L'approche que je viens d'utiliser consistait simplement à ajouter CornerRadius à la grille "RootGrid" du modèle Button.
<Style TargetType="Button" x:Key="RoundedButton">
...
<Grid x:Name="RootGrid" CornerRadius="10" Background="{TemplateBinding Background}">
...
</Style>
