在#WPF中有ItemTemplateSelectors。但是,您是否也可以根據綁定對象的數據類型選擇一個ItemContainerStyle?在WPF中,根據數據綁定內容選擇ItemContainerStyle
我是數據綁定散點圖。我想根據DataContext中的對象設置生成的ScatterViewItems的一些屬性。對於樣式,類似於ItemTemplateSelector的機制會很好。這是否可能?我現在將綁定到我顯示的對象中的屬性以獲得效果,但是這感覺像是開銷和太複雜(並且最重要的是,我們的XU設計人員自己無法完成的事情)。
這是我現在使用的XAML。非常感謝您的幫助。

<s:ScatterView.ItemTemplateSelector>

<s:SurfaceButton Visibility="{Binding MailToVisible}" x:Name="mailto" Tag="{Binding Titel}" Click="mailto_Click" HorizontalAlignment="Right" VerticalAlignment="Top" Background="Transparent" Width="62" Height="36">
