这类似于disabling selection of a single item，但是，我想保持项目启用（对于tap，aka click事件）。因此，将IsEnabled简单设置为false显然不是一个选项。什么是实现这一目标的好方法？
答案 0 :(得分：0)
给项目绑定一个bool类型的额外属性（例如canBeSelected），处理selectionchanged事件并检查bool是否为false，如果将selecteditem设置为null

您可以使用自定义样式解决此问题。
用法：
<GridViewItem Style="{StaticResource NonGridViewItemStyle}">
<!-- Your content here-->
</GridViewItem>
将此样式放在资源字典中：
<Style x:Key="NonGridViewItemStyle"
TargetType="GridViewItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="GridViewItem">
