示例

下面的代码示例演示如何使用 ASP.NET 网页中PartChromeType引用的自定义WebPart控件来声明枚举。The following code examples demonstrate the declarative use of the PartChromeType enumeration by using a custom WebPart control referenced in an ASP.NET Web page. 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, 你可以将源代码放在站点的 App_Code 文件夹中, 在此文件夹中, 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.

该示例的第一部分包含名TextDisplayWebPart为的自定义控件的代码。The first part of the example contains the code for the custom control, named TextDisplayWebPart. 由于WebPart控件派生自, 因此它还继承Part ChromeType类提供的公共属性, 包括属性, 该属性使用PartChromeType枚举作为其返回类型。Because the control derives from WebPart, it also inherits the common properties that the Part class provides, including the ChromeType property, which uses the PartChromeType enumeration as its return type.

请注意, 在网页的声明性标记中, TextDisplayWebPart控件的第二个实例将其ChromeType属性值设置为 titleonly.rdl。Note that in the declarative markup for the Web page, the second instance of the TextDisplayWebPart control sets its ChromeType property value to TitleOnly. 在浏览器中加载页面后, 第二个控制实例会最小化显示。After you load the page in a browser, the second control instance appears minimized. 展开第二个控件时, 它只有一个不带边框的标题栏。When you expand the second control, it has only a title bar without a border.

注解

部件控件的PartChromeType枚举确定环绕 Web 部件控件的边框类型。A part control's PartChromeType enumeration determines what kind of border surrounds a Web Parts control. 选项包括只显示标题栏、仅显示边框、标题栏和边框, 或者两者都不显示。Options include showing a title bar only, a border only, a title bar and border, or neither.

如果在部件控件的ChromeType属性上将枚举值设置为 "默认值", 则控件会PartChromeType从包含控件的区域的属性继承其设置。If the enumeration value is set to Default on the ChromeType property of a part control, the control inherits its setting from the PartChromeType property of the zone that contains the control.
