注意：此字段在 .NET Framework 2.0 版中是新增的。
表示包含 Web 部件控件的页的默认显示模式。此字段为只读。
命名空间:System.Web.UI.WebControls.WebParts
程序集:System.Web（在 system.web.dll 中）
Public Shared ReadOnly BrowseDisplayMode As WebPartDisplayMode
Dim value As WebPartDisplayMode
value = WebPartManager.BrowseDisplayMode
public static readonly WebPartDisplayMode BrowseDisplayMode
public:
static initonly WebPartDisplayMode^ BrowseDisplayMode
public static final WebPartDisplayMode BrowseDisplayMode
public static final var BrowseDisplayMode : WebPartDisplayMode
BrowseDisplayMode 字段引用一个自定义 WebPartDisplayMode 对象，该对象由 WebPartManager 控件创建，并包含在该控件中。因为这是一个静态对象，所以可以通过 WebPartManager 类直接引用它，而无需该控件的实例。
默认情况下，包含 Web 部件的页在首次加载时处于 BrowseDisplayMode（浏览模式）。如果用户只是像在正常网页上那样进行浏览，则该页应保持为浏览模式。如果用户希望对某一页的页面布局、控件、外观或行为进行个性化设置，则必须将该页切换至专用显示模式之一，这些专用模式可通过 SupportedDisplayModes 属性获取。
下面的代码示例演示如何以编程方式使用 BrowseDisplayMode 字段。此代码使用受支持的显示模式（在此示例中是浏览模式和设计模式）填充一个下拉列表。注意，在 Page_PreRender 方法中，代码会检查当前 DisplayMode 属性是否设置为 BrowseDisplayMode。如果是，则 Label1 将可见；否则 Label1 将隐藏。

默认情况下，在浏览器中加载页后会处于浏览模式。注意，页上的标签指示您正处于浏览模式。使用下拉列表控件将页切换至设计模式。注意，由于 Page_PreRender 方法中的代码，该标签现在处于隐藏状态。
