PageCatalogPart 类

定义

提供保留对所有 WebPart 控件(以及包含在 WebPartZoneBase 区域中的其他服务器控件)的引用的目录(用户已在单个 Web 部件页关闭了这些控件),这使得用户能够将已关闭的控件添加回页面。Provides a catalog that keeps references to all WebPart controls (and other server controls contained in WebPartZoneBase zones) that a user has closed on a single Web Parts page, which enables users to add the closed controls back to the page. 无法继承此类。This class cannot be inherited.

示例

下面的代码示例演示如何在网页上以声明方式使用 PageCatalogPart 控件。The following code example demonstrates how to use the PageCatalogPart control declaratively on a Web page. 此示例包含四个部分:This example has four parts:

  • 使您能够在 Web 部件页上更改显示模式的用户控件。A user control that enables you to change display modes on a Web Parts page.

  • 包含 CatalogZone 控件、PageCatalogPart 控件和 DeclarativeCatalogPart 控件的网页。A Web page that contains a CatalogZone control, a PageCatalogPart control, and a DeclarativeCatalogPart control.

  • 一个源代码文件,其中包含两个自定义 WebPart 控件。A source code file that contains two custom WebPart controls.

  • 说明如何在浏览器中加载页面时工作。An explanation of how the example works when you load the page in a browser.

此代码示例的第一部分是用户控件,该控件使用户能够更改网页上的显示模式。The first part of this code example is the user control that enables users to change display modes on a Web page. 有关显示模式的详细信息以及此控件中源代码的说明,请参阅演练:在 Web 部件页上更改显示模式For details about display modes and a description of the source code in this control, see Walkthrough: Changing Display Modes on a Web Parts Page.

此代码示例的第三部分是两个 WebPart 控件的源代码。The third part of the code example is the source code for the two WebPart controls. 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. 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.

在浏览器中加载页面时,请在 "显示模式" 下拉列表控件中选择 "目录模式" 以切换到目录模式。When you load the page in a browser, select Catalog Mode in the Display Mode drop-down list control to switch to catalog mode. 在目录模式下,可以看到可添加到页面的控件。In catalog mode, you can see the controls that are available to be added to the page. 添加一个控件,然后使用 "显示模式" 下拉列表控件将该页返回到 "浏览" 模式。Add one of the controls, then use the Display Mode drop-down list control to return the page to browse mode. 单击其中一个控件的标题栏中的谓词菜单(向下箭头),然后单击 "关闭" 以关闭控件。Click the verbs menu (the downward arrow) in the title bar of one of the controls, and click Close to close the control. 将页返回到目录模式,注意关闭的控件将显示在页目录中,并可重新添加回页面。Return the page to catalog mode, and notice that the control you closed now appears in the page catalog, and is available to be added back to the page.

注解

PageCatalogPart 类在 Web 部件页上提供了一个非常具体的用途:它充当页面目录来维护以前添加到用户关闭的页面的任何控件,以便用户可以将它们添加回页面。The PageCatalogPart class serves one very specific purpose on a Web Parts page: it acts as a page catalog to maintain any controls previously added to the page that a user has closed, so that the user can add them back to the page. 仅当网页处于目录显示模式时,此控件才可见,这是一个允许用户在页面上添加和移除控件的特殊视图。This control is visible only when a Web page is in catalog display mode, a special view that enables users to add and remove controls on the page. 如果希望为用户提供关闭和重新打开控件的灵活性,请将 PageCatalogPart 控件添加到页面中。Add a PageCatalogPart control to your page if you want to provide users with the flexibility of closing and reopening controls. 如果页面不允许用户关闭控件,则无需向页面添加 PageCatalogPart 控件。If your page does not allow users to close controls at all, there is no need to add a PageCatalogPart control to your page.

仅将已关闭的控件添加到页目录中。Only closed controls are added to the page catalog. 关闭的控件具有几个属性:A closed control has several attributes:

  • 它在页面上不可见。It is not visible on the page.

  • 它不会在页上呈现。It is not rendered on the page.

  • 它不参与页生命周期阶段。It does not participate in page life-cycle phases.

关闭控件不同于删除控件,而是将其从页中永久删除。Closing a control is different from deleting it, which permanently removes it from the page. 用户可以从页目录重新打开已关闭的控件实例,但在用户删除控件之后,就不能再恢复该特定实例了。A user can reopen a closed control instance from a page catalog, but after a user deletes a control, he or she can never recover that specific instance.

向页添加 PageCatalogPart 控件的最常见且最方便的方法是将其声明为页持久性格式。The most common and convenient way to add a PageCatalogPart control to a page is by declaring it in page persistence format. 与任何声明性 CatalogPart 控件一样,必须在网页上 ASP.NET 标记元素的正确上下文中声明 PageCatalogPart 控件。As with any declarative CatalogPart control, a PageCatalogPart control must be declared within the proper context of ASP.NET markup elements on a Web page. 有关如何在网页中声明 PageCatalogPart 控件的工作代码示例,请参阅本主题的 "示例" 部分。For a working code example of how to declare a PageCatalogPart control in a Web page, see the Example section of this topic. 必须将以下声明性元素序列添加到页面:You must add the following sequence of declarative elements to the page:

  1. 必须声明 <asp:catalogzone> 元素,并且必须向其添加子 <zonetemplate> 元素,以包含在该区域中声明的所有 CatalogPart 控件。An <asp:catalogzone> element must be declared, and a child <zonetemplate> element must be added to it to contain any CatalogPart controls declared in the zone.

  2. <asp:pagecatalogpart> 元素必须作为 <zonetemplate> 元素的子元素添加。An <asp:pagecatalogpart> element must be added as a child of the <zonetemplate> element. 还可能有其他 CatalogPart 控件声明为 <zonetemplate> 元素的子元素,包括 DeclarativeCatalogPartImportCatalogPart 控件。There might also be other CatalogPart controls declared as child elements of the <zonetemplate> element, including DeclarativeCatalogPart or ImportCatalogPart controls.

PageCatalogPart 类只有一个可用属性,即 Title 属性,该属性重写基属性,以便在未提供值的情况下可以为页目录提供默认标题。The PageCatalogPart class has only one usable property, the Title property, which overrides the base property so that a default title can be provided for the page catalog if no value is supplied.

PageCatalogPart 类的其余属性会重写继承的属性,但实际上并不用于呈现控件。The remaining properties for the PageCatalogPart class override the inherited properties, but are not actually used for rendering the control. 它们只会被重写,以便可以对它们进行特殊代码属性的设置,以将其从 Microsoft Visual Studio 2005Microsoft Visual Studio 2005等设计工具中隐藏。They are overridden only so that special code attributes can be set on them to hide them from design tools like Microsoft Visual Studio 2005Microsoft Visual Studio 2005. 不应使用这些隐藏属性,因为它们对呈现没有影响。You should not use these hidden properties, because they have no effect on rendering. 这一事实是,它们在 IntelliSense 中是隐藏的,Visual Studio 中的 "属性" 窗格可帮助开发人员避免错误地使用它们。The fact that they are hidden from IntelliSense and the Properties pane in Visual Studio helps developers avoid using them by mistake. 所有这些隐藏属性在各自的帮助主题中都有相应的记录。All these hidden properties are noted as such in their respective Help topics.

PageCatalogPart 类还具有几个重要的方法。The PageCatalogPart class also has several important methods. GetAvailableWebPartDescriptions 方法为页目录中的每个 WebPart 控件检索一个 WebPartDescription 对象,这使 PageCatalogPart 控件可以显示有关每个服务器控件的信息,而无需创建该控件的实例。The GetAvailableWebPartDescriptions method retrieves a WebPartDescription object for each WebPart control in the page catalog, which enables a PageCatalogPart control to display information about each server control without having to create an instance of that control. 另一种方法是 GetWebPart 方法。Another method is the GetWebPart method. 此方法根据传递给方法的说明获取特定 WebPart 控件的实例。This method gets an instance of a particular WebPart control, based on the description passed to the method.

可访问性Accessibility

默认情况下,为此控件呈现的标记可能不符合辅助功能标准,例如 Web 内容可访问性准则1.0 (WCAG)优先级1指导原则。The markup rendered by default for this control might not conform to accessibility standards such as the Web Content Accessibility Guidelines 1.0 (WCAG) priority 1 guidelines. 有关此控件的辅助功能支持的详细信息,请参阅ASP.NET 控件和辅助功能For details about accessibility support for this control, see ASP.NET Controls and Accessibility.
