注解

NodeStyle使用 属性可控制控件呈现的所有导航路径节点的显示文本的外观。 默认情况下，显示文本是在表示页面的 的 SiteMapNode 属性中指定的Title。 常见样式设置包括自定义背景色、前景色、字体属性和节点间距。

对于 SiteMapPath 节点，样式属性按以下顺序合并为单个样式：

  1. NodeStyle

  2. CurrentNodeStyle 或 RootNodeStyle，具体取决于节点类型。

注意

如果将节点字体样式设置为删除线或上划线样式，则除非将其显式设置为 true，否则不会显示节点的默认下划线样式。

NodeStyle如果定义了 ，则它最初将应用于每个节点。 如果为特定类型的节点（如根节点或当前节点）定义了其他样式，则此样式将取代 属性中指定的 NodeStyle 常规样式。 如果为特定类型的节点定义了模板，它将取代该节点的所有已定义样式。
