Comentários

Use a ItemSeparatorTemplate propriedade para definir o conteúdo do separador entre itens únicos do ListView controle. O ItemSeparatorTemplate é exibido após cada item, exceto o último.

Para especificar o modelo personalizado declarativamente, adicione um ItemSeparatorTemplate elemento dentro do ListView controle . Em seguida, você pode adicionar o conteúdo do modelo ao ItemSeparatorTemplate elemento .
