WebPart 类

定义

用作自定义 ASP.NET Web 部件控件的基类,从而 Part 基类功能添加一些附加用户界面 (UI) 属性、创建连接的能力以及个性化行为。Serves as the base class for custom ASP.NET Web Parts controls, adding to the base Part class features some additional user interface (UI) properties, the ability to create connections, and personalization behavior.

示例

下面的代码示例演示如何创建 WebPart 控件并在网页中引用它。The following code example demonstrates how to create a WebPart control and reference it in a Web page.

该示例的第一部分包含名为 TextDisplayWebPart的自定义 WebPart 控件的代码。The first part of the example contains the code for a custom WebPart control named TextDisplayWebPart. 此控件演示如何创建一个简单的自定义 WebPart 控件,该控件允许您访问 Web 部件控件集的功能。This control demonstrates how to create a simple custom WebPart control that gives you access to the features of the Web Parts control set. 要使代码示例运行,必须编译此源代码。For the code example to run, you must compile this source code. 可以显式编译该程序集,并将生成的程序集放在网站的 Bin 文件夹或全局程序集缓存中。You can compile it explicitly and put the resulting assembly in your Web site's Bin folder or the global assembly cache. 或者,您可以将源代码放在站点的 App_Code 文件夹中,它将在运行时动态编译。Alternatively, you can put the source code in your site's App_Code folder, where it will be dynamically compiled at run time. 此代码示例假定您将源代码编译成一个程序集,将其放在您的 Web 应用程序的 Bin 子文件夹中,并在您的网页中使用 Register 指令引用该程序集。This code example assumes that you compile the source code into an assembly, place it in a Bin subfolder of your Web application, and reference the assembly with a Register directive in your Web page. 有关演示两种编译方法的演练,请参阅演练:开发和使用自定义 Web 服务器控件For a walkthrough that demonstrates both methods of compiling, see Walkthrough: Developing and Using a Custom Web Server Control.

注解

创建具有 Web 部件功能的控件时,有两个基本选项。When you create controls with Web Parts functionality, you have two basic options. 您可以创建从 WebPart 类派生的自定义控件,也可以创建或使用其他服务器控件。You can create custom controls that derive from the WebPart class, or you can create or use other server controls. 现有的 ASP.NET 控件、自定义服务器控件和用户控件均可通过在 WebPartZone 区域控件中声明它们(或以编程方式将它们添加到)来获得完全 Web 部件功能,结果是这些控件将在运行时 GenericWebPart 对象进行包装并被视为真正的 WebPart 控件。Existing ASP.NET controls, custom server controls, and user controls can all be given full Web Parts functionality by declaring them within (or adding them programmatically to) a WebPartZone zone control, with the result that they will be wrapped with GenericWebPart objects at run time and treated as true WebPart controls. 有关详细信息,请参阅 GenericWebPart 类的文档。For details, see the documentation for the GenericWebPart class. 为了加快开发速度和最大程度地重复使用代码,使用现有服务器控件可能是一个不错的选择。For speed of development and maximum reuse of code, using existing server controls can be a good option. 为了最大程度地控制控件的行为和 Web 部件功能,创建从 WebPart 类继承的自定义控件通常是最佳选项。For maximum programmatic control over the behavior and Web Parts functionality of controls, creating a custom control that inherits from the WebPart class is often the best option.

Abstract WebPart 类继承自基 Part 控件,并为所有 WebPart 控件提供基本元素。The abstract WebPart class inherits from the base Part control and provides the basic elements for all WebPart controls. 类包含一组影响 UI 外观的公共属性。The class includes a common set of properties that affect the appearance of the UI. AllowCloseAllowConnectAllowEditAllowHideAllowMinimizeAllowZoneChange 属性分别指定是否允许 Web 应用程序的用户以给定属性名称指示的方式与部件控件交互。The AllowClose, AllowConnect, AllowEdit, AllowHide, AllowMinimize, and AllowZoneChange properties each specify whether the user of a Web application is permitted to interact with the part control in the way indicated by the given property name. CatalogIconImageUrlChromeStateChromeTypeDescriptionHeightHelpUrlHiddenTitleTitleIconImageUrlTitleUrlWidth 属性确定 WebPart 控件的大小、可见性、外观和支持内容(例如标题和说明)。The CatalogIconImageUrl, ChromeState, ChromeType, Description, Height, HelpUrl, Hidden, Title, TitleIconImageUrl, TitleUrl, and Width properties determine the size, visibility, appearance, and supporting content (such as a title and a description) for a WebPart control.

WebPart 控件在 Web 部件控件集内的上下文之间的关系是由属性(如 WebPartManager)确定的,这些属性包含对控件的关联 WebPartManager 对象的引用,而 Zone引用包含控件的 WebZoneThe relationship of a WebPart control to its context within the Web Parts control set is determined by properties such as WebPartManager, which holds a reference to the control's associated WebPartManager object, and Zone, which references the WebZone that contains the control. 每页只能有一个 WebPartManager 控件,每个 WebPart 控件的实例一次只能驻留在一个 WebZone 中。There can be only one WebPartManager control per page, and each instance of a WebPart control can reside within only one WebZone at a time.

备注

WebPart 控件可以放置在某个区域的外部,但在这种情况下,它将作为常规的服务器控件,几乎所有 Web 部件功能都将丢失。A WebPart control can be placed outside of a zone on a Web page, but in this case it functions as a normal server control and loses nearly all Web Parts functionality.

其他几个重要属性会影响 WebPart 控件的独特功能。Several other important properties affect unique features of WebPart controls. AuthorizationFilter 属性允许开发人员设置任意字符串,该字符串可在运行时用作筛选器,以确定控件是否已添加到页面中。The AuthorizationFilter property allows developers to set an arbitrary string that can be used as a filter at run time to determine whether a control is added to the page. 与功能(如角色管理)结合使用时,AuthorizationFilter 属性提供了一种用于基于定义的用户角色创建视图的有用机制。Used together with a feature such as role management, the AuthorizationFilter property provides a useful mechanism for creating views based on defined user roles. ExportMode 属性指示在导出过程中是导出控件上的所有可用属性数据,还是仅导出非敏感数据。The ExportMode property indicates whether, during an export, all the available property data on a control is exported, or only the non-sensitive data. 出于安全目的,开发人员可以区分敏感数据和不是数据的数据。This allows developers to distinguish between data that is sensitive and data that is not, for security purposes. WebBrowsableObject 属性返回对 WebPart 控件的实例的引用,以便 EditorPart 控件在该页处于编辑模式时可以对其进行编辑。The WebBrowsableObject property returns a reference to an instance of a WebPart control, so that an EditorPart control can edit it when the page is in edit mode. 最后,有几个属性,这些属性相对于页面的其余部分指示控件的状态。Finally, there are several properties that indicate the status of the control relative to the rest of the page. IsClosed 属性指示控件是否已关闭(因而添加到 PageCatalogPart 对象),或是否已打开且在该页上可用。The IsClosed property indicates whether a control is closed (and thus added to a PageCatalogPart object), or if it is open and available on the page. IsShared 属性指示控件是否为共享控件(与用户特定的控件),这意味着它对于网页的所有用户均可见。The IsShared property indicates whether a control is a shared control (versus a user-specific control), meaning that it is visible to all users of a Web page. IsStandalone 属性指示控件当前是否包含在 WebPartZoneBase派生的区域中(如 WebPartZone)。The IsStandalone property indicates whether a control is currently contained in a WebPartZoneBase-derived zone (such as WebPartZone). false 指示控件在区域内,因此具有完全 Web 部件功能。A value of false indicates the control is inside a zone and thus has full Web Parts functionality. IsStatic 属性指示控件是静态的还是动态的。The IsStatic property indicates whether a control is static or dynamic. 静态控件在网页的标记中声明,而动态控件则以编程方式添加。A static control is declared in the markup of a Web page, whereas a dynamic control is added programmatically.

WebPart 类还提供了若干方法来确定控件生命周期中不同点发生的情况。The WebPart class also provides several methods that determine what happens at various points in the control's life cycle. 例如,可以在派生类中重写 OnConnectModeChangedOnEditModeChanged 方法,以便在与每个方法的名称相对应的事件期间,提供对控件内容呈现的编程控制。For example, the OnConnectModeChanged and OnEditModeChanged methods can both be overridden in a derived class to provide programmatic control over the rendering of a control's contents during the event that corresponds to each method's name.

派生自 WebPart 的类可以将 WebPartVerb 对象添加到 Verbs 集合。Classes that derive from WebPart can add WebPartVerb objects to the Verbs collection. 谓词在谓词菜单中呈现,谓词菜单显示在 WebPart 控件的标题栏中。The verbs are rendered in a verbs menu, which appears in the title bar of a WebPart control. WebPartVerb 对象为常见用户操作(例如隐藏或最小化控件或显示帮助)提供简单的 UI 元素。WebPartVerb objects provide simple UI elements for common user actions such as hiding or minimizing the control or displaying Help.

CreateEditorParts 方法创建与 WebPart 控件关联的任何自定义 EditorPart 控件的集合。The CreateEditorParts method creates a collection of any custom EditorPart controls that are associated with a WebPart control. 开发人员可以重写此方法,以便创建专门用于编辑其 WebPart 控件的自定义控件。Developers can override this method so that it creates custom controls designed specifically to edit their WebPart control. 当用户单击 WebPart 控件上的编辑谓词时,将调用方法。The method is called when a user clicks the edit verb on a WebPart control.
