示例

下面的代码示例演示如何以声明方式和EditorPart编程方式使用控件。The following code example demonstrates declarative and programmatic use of EditorPart controls. 此代码示例包含四个部分:This code 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.

  • 一个网页, 其中包含一个EditorZone控件, 其中包含在区域EditorPart中声明的 Web 部件控件集中的多个控件, 以及对自定义WebPart控件的引用。A Web page that contains an EditorZone control, with several of the EditorPart controls from the Web Parts control set declared in the zone, and a reference to a custom WebPart control.

  • 一个包含自定义WebPart控件的类, 以及一个用于在WebPart控件中编辑属性的自定义EditorPart控件。A class that contains the custom WebPart control, and a custom EditorPart control for editing a property in the WebPart control.

  • 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:更改 Web 部件页上的显示模式。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名为WebPart TextDisplayWebPart的自定义类。The third part of the code example is a custom WebPart class named TextDisplayWebPart. 类实现IWebEditable接口。The class implements the IWebEditable interface. 此类中包含一个嵌套的私有类, 其中包含EditorPart TextDisplayWebPart与类关联并名为TextDisplayEditorPart的私有类的代码。Within this class is a nested, private class that contains the code for a private EditorPart class associated with the TextDisplayWebPart class and named TextDisplayEditorPart. 在运行时, TextDisplayWebPart当控件进入编辑模式时, 它在其TextDisplayWebPart.CreateEditorParts方法中TextDisplayEditorPart创建类的一个实例, 并在EditorZone控件中显示该实例以及其他EditorPart控件。At run time, as the TextDisplayWebPart control enters edit mode, in its TextDisplayWebPart.CreateEditorParts method, it creates an instance of the TextDisplayEditorPart class, and displays it in the EditorZone control, along with the other EditorPart controls.

在浏览器中加载页面, 然后在 "显示模式" 控件上选择 "编辑模式" 以切换到编辑模式。Load the page in a browser, and on the Display Mode control, select Edit Mode to switch to edit mode. 单击TextDisplayWebPart控件标题栏中的谓词菜单 (向下箭头), 然后单击 "编辑" 以编辑控件。Click the verbs menu (the downward arrow) in the title bar of the TextDisplayWebPart control, and click Edit to edit the control. 编辑 UI 可见后, 可以看到三个EditorPart控件, 其中包括用于TextDisplayWebPart.FontStyle编辑属性的自定义控件。When the editing UI is visible, you can see three EditorPart controls, including the custom one that enables you to edit the TextDisplayWebPart.FontStyle property. 如果在编辑 UI 中进行一些更改, 并单击 "应用" 按钮, 则可以使用下拉列表控件将页面返回到浏览模式, 并查看编辑更改的完整效果。If you make some changes in the editing UI and click the Apply button, you can use the drop-down list control to return the page to browse mode and see the full effect of the editing changes.

注解

类提供由 Web 部件控件集提供的派生EditorPart控件和自定义EditorPart控件使用的一组基本属性和方法。 EditorPartThe EditorPart class provides a base set of properties and methods that are used by the derived EditorPart controls provided with the Web Parts control set, and by custom EditorPart controls. 控件允许用户通过修改关联WebPart控件的布局、外观、属性、行为或其他特征来对其进行编辑。 EditorPartAn EditorPart control allows a user to edit an associated WebPart control by modifying its layout, appearance, properties, behavior, or other characteristics.

编辑用户界面 (UI) 由包含EditorZoneBase EditorPart控件的区域组成, 在网页进入编辑模式后显示。The editing user interface (UI), which consists of EditorZoneBase zones that contain EditorPart controls, is displayed after a Web page enters edit mode.

备注

只能在派生EditorZoneBaseEditorZone类的区域中使用控件EditorPart , 例如控件。An EditorPart control can be used only within a zone that derives from the EditorZoneBase class, such as the EditorZone control.

在页面进入编辑模式后, 用户可以通过单击所选WebPart控件的谓词菜单上的编辑谓词来选择要编辑的控件。After a page has entered edit mode, a user can select a WebPart control to edit by clicking an edit verb on the verbs menu of the selected control. 一次WebPart只能编辑一个控件。Only one WebPart control can be edited at a time.

以下表格EditorPart中列出了若干派生控件, Web 部件控件集。Several derived EditorPart controls are provided with the Web Parts control set, as listed in the following table. 这些控件提供大多数应用程序所需的所有编辑功能。These controls provide all the editing capabilities that are necessary for most applications. 在 Web 部件页中使用这些控件的典型方法是在<zonetemplate>元素内将它们声明为页持久性格式, 其中<zonetemplate><asp:editorzone>元素的子元素。The typical approach for using these controls in a Web Parts page is to declare them in page persistence format within a <zonetemplate> element, where <zonetemplate> is the child element of an <asp:editorzone> element. 有关代码示例, 请参阅本主题的 "示例" 部分。For a code example, see the Example section of this topic.

控件类型Type of control 说明Description
AppearanceEditorPart 编辑关联控件的外观, 包括属性, 如其标题文本、高度、宽度和边框属性。Edits the appearance of the associated control, including properties such as its title text, height, width, and border attributes.
BehaviorEditorPart 编辑关联控件的某些行为, 例如是否可对其进行编辑、是否可将其关闭, 或是否可将其移动到另一个区域。Edits certain behaviors of the associated control, such as whether it can be edited, whether it can be closed, or whether it can be moved to another zone. 仅当在共享个性化设置范围内编辑控件时, 此控件才会显示在页面上。This control is only visible on a page when a control is being edited in shared personalization scope.
LayoutEditorPart 编辑关联控件的布局特性, 例如它是处于正常还是最小化 (折叠) 状态, 以及它所处的区域。Edits layout attributes for the associated control, such as whether it is in a normal or minimized (collapsed) state, and what zone it is placed in.
PropertyGridEditorPart 如果在源代码中使用WebBrowsable属性声明了这些属性, 则编辑关联控件的属性。Edits properties of the associated control, if those properties were declared in the source code with a WebBrowsable attribute.

备注

为了提高可访问性, EditorPart Web 部件控件集中提供的所有控件都呈现在<fieldset>元素中。To improve accessibility, all the EditorPart controls provided in the Web Parts control set are rendered within a <fieldset> element. 元素对用于在给定EditorPart控件中进行编辑的相关控件集进行分组, 并为可视化用户代理 (如普通 Web 浏览器) 和面向语音的用户代理等控件中的选项卡式导航提供便利。 <fieldset>(如屏幕阅读软件)。The <fieldset> element groups the related set of controls used for editing in a given EditorPart control, and it facilitates tabbed navigation among those controls for both visual user agents (such as ordinary Web browsers) and speech-oriented user agents (such as screen-reading software).

实施者说明

若要创建自EditorPart定义控件, 必须重写两个重要的方法。To create a custom EditorPart control, you must override two important methods. 方法将编辑器控件中所做的更改应用于WebPart要编辑的控件。 ApplyChanges()The ApplyChanges() method applies changes made in the editor control to the WebPart control being edited. 方法获取正在编辑的WebPart控件的当前值, 以便编辑器控件可以对其进行编辑。 SyncChanges()The SyncChanges() method gets the current values of the WebPart control being edited, so that the editor control can edit them. 使用这两个关键方法, 可以获取和设置自定义EditorPart控件与其正在编辑的控件之间的WebPart值。Using these two critical methods, you get and set values between your custom EditorPart control and the WebPart control it is editing.

如果从EditorPart类派生以创建自定义编辑器控件, 则可以通过在WebPart控件、用户控件或EditorZoneBase服务器控件中实现IWebEditable接口, 将自定义控件添加到区域。If you derive from the EditorPart class to create custom editor controls, you can add your custom controls to an EditorZoneBase zone by implementing the IWebEditable interface in a WebPart control, a user control, or a server control. 有关更多详细信息和代码示例, 请IWebEditable参阅类概述。For more details and a code example, see the IWebEditable class overview. 此外, "示例" 部分中的代码示例演示如何在IWebEditable自定义WebPart控件中实现。Also, the code example in the Example section demonstrates how to implement IWebEditable in a custom WebPart control.
