表示包含 Web 部件控件的页的默认显示模式。此字段为只读。

public: static initonly System::Web::UI::WebControls::WebParts::WebPartDisplayMode ^ BrowseDisplayMode;

public static readonly System.Web.UI.WebControls.WebParts.WebPartDisplayMode BrowseDisplayMode;

 staticval mutable BrowseDisplayMode : System.Web.UI.WebControls.WebParts.WebPartDisplayMode

Public Shared ReadOnly BrowseDisplayMode As WebPartDisplayMode

字段值

WebPartDisplayMode

示例

下面的代码示例演示如何以编程方式处理 BrowseDisplayMode 字段。代码使用支持的显示模式（在本例中为浏览和设计）填充下拉列表。请注意，在方法中 Page_PreRender ，代码检查当前 DisplayMode 属性是否设置为 BrowseDisplayMode。如果是这样， Label1 将可见，否则 Label1 将隐藏。

在浏览器中加载页面后，默认情况下处于浏览模式。请注意页面上指示你处于浏览模式的标签。使用下拉列表控件将页面切换到设计模式。请注意，由于方法中的 Page_PreRender 代码，标签现已隐藏。

注解

字段BrowseDisplayMode引用控件创建并包含的WebPartManager自定义WebPartDisplayMode对象。由于这是静态对象，因此可以直接通过 WebPartManager 类引用它，而无需控件的实例。

当包含 Web 部件控件的页面首次加载时，它默认处于 BrowseDisplayMode (浏览模式) 。当用户像在普通网页上一样浏览时，页面将保持浏览模式。如果用户想要对页面的布局、控件、外观或行为进行个性化设置，则必须将页面切换到通过 SupportedDisplayModes 属性提供的专用显示模式之一。
