介绍Introduction

使用Button控件允许用户以发布到服务器的页面的网页上创建推送按钮。Use the Button control to create a push button on the Web page that lets users to post a page to the server. 该控件将触发可处理以响应回发的服务器代码中的事件。The control triggers an event in server code that you can handle to respond to the postback. 它还可能会引发之前发布页面或可运行和后取消提交的页面可以处理的客户端脚本中的事件。It can also raise an event in client script that you can handle before the page is posted or that can run and then cancel submission of the page.

备注

ASP.NET 包括多种类型的按钮控件,其中每个在网页以不同方式显示。ASP.NET includes several kinds of button controls, each of which appears differently on Web pages. 它们是Button控件,它将呈现为按下按钮;LinkButton控件,它将呈现为链接; 并且ImageButton控件,它将呈现为图像; 和ImageMap控件,它允许您创建具有热点的图形,用户可以单击。They are the Button control, which renders as a push button; the LinkButton control, which renders as a link; and the ImageButton control, which renders as an image; and the ImageMap control, which lets you create a graphic that has hotspots that users can click. 默认情况下,所有按钮控件都提交时单击该页面。By default, all button controls submit the page when clicked. 此外可以使用HtmlButtonHtmlInputButton控件在页上创建按钮才在服务器代码中可编程的。You can also use the HtmlButton and HtmlInputButton controls to create buttons on the page that are programmable in server code. HTML 和 Web 服务器控件之间的差异的详细信息,请参阅ASP.NET Web 服务器控件概述For details about the differences between HTML and Web server controls, see ASP.NET Web Server Controls Overview.

默认情况下,Button控件是一个提交按钮。By default, a Button control is a Submit button. 一个提交按钮没有命令名称 (由指定CommandName属性) 的按钮和只是将网页回发到服务器关联。A Submit button does not have a command name (specified by the CommandName property) associated with the button and simply posts the Web page back to the server. 你可以提供的事件处理程序Click事件以编程方式控制的操作执行时单击提交按钮。You can provide an event handler for the Click event to programmatically control the actions performed when the Submit button is clicked.

命令按钮有与该按钮,如关联的命令名称Sort,通过设置CommandName属性。A Command button has a command name associated with the button, such as Sort, by setting the CommandName property. 这使您可以创建多个Button在 Web 上的控件,并以编程方式确定哪些Button单击控件。This allows you to create multiple Button controls on a Web page and programmatically determine which Button control is clicked. 此外可以使用CommandArgument命令按钮,以提供其他信息的命令执行,如具有属性AscendingYou can also use the CommandArgument property with a command button to provide additional information about the command to perform, such as Ascending. 你可以提供的事件处理程序Command单击命令按钮时执行的事件以编程方式控制的操作。You can provide an event handler for the Command event to programmatically control the actions performed when the Command button is clicked.

按钮的回发行为和服务器事件Button Postback Behavior and Server Events

当用户单击任何 Web 服务器控件按钮时,则将页发送到服务器。When a user clicks any Web server control button, the page is sent to the server. 这使得 Web 页以进行处理,在基于服务器的代码中引发任何挂起的事件。This causes the Web page to be processed and any pending events to be raised in server-based code. 在所有页面和控件处理已都完成,页面本身到浏览器将重新呈现。When all page and control processing has finished, the page renders itself to the browser again.

该按钮可以引发其自己Click事件或Command事件,您可以通过使用基于服务器的代码处理。The buttons can raise their own Click events or Command event, which you can handle by using server-based code. 这是不同于传统的 HTML 页中或在基于客户端的 Web 应用程序中,事件在按钮的onclick可通过在客户端中运行的 JavaScript 处理事件。This is different than events in traditional HTML pages or in client-based Web applications, where a button's onclick event is handled by using JavaScript that runs in the client. 有关详细信息,请参阅ASP.NET Web 窗体服务器控件事件模型For more information, see ASP.NET Web Forms Server Control Event Model.

当用户单击按钮控件时,页面回发到服务器。When users click a button control, the page is posted back to the server. 默认情况下,页面回发到自身,By default, the page is posted back to itself,

你可以配置要发布到另一页的当前页的按钮。You can configure buttons to post the current page to another page. 这可用于创建多页窗体。This can be useful for creating multi-page forms. 有关详细信息,请参阅跨页面发送在 ASP.NET Web 窗体For details, see Cross-Page Posting in ASP.NET Web Forms.

客户端脚本中处理按钮事件Handling Button Events in Client Script

按钮控件可以引发服务器事件和客户端事件。Button controls can raise both server events and client events. 服务器事件发生回发后,以及为页面编写服务器端代码中处理。Server events occur after postback, and they are handled in the server-side code that you write for the page. 客户端事件处理在客户端脚本中,通常 ECMAScript (JavaScript),并提交页之前引发。Client events are handled in client script, typically ECMAScript (JavaScript), and are raised before the page is submitted. 通过将客户端事件添加到 ASP.NET 按钮控件,可以执行任务,例如在提交页上之前, 显示确认对话框,并可能会取消提交。By adding client-side events to ASP.NET button controls, you can perform tasks such as displaying confirmation dialog boxes before submitting the page, and potentially cancel the submission. 有关详细信息,请参阅客户端脚本在 ASP.NET Web Pages如何:响应客户端脚本中的按钮 Web 服务器控件事件For details, see Client Script in ASP.NET Web Pages and How to: Respond to Button Web Server Control Events in Client Script.

您可能还想Button控件还使用客户端脚本来执行回发 (而不是只需执行 HTTP POST 操作)。You might also want the Button control to also use client script to perform the postback (instead of simply performing an HTTP POST operation). 这很有用,如果你想要以编程方式操作回发,例如将其附加到页面上其他元素。This can be useful if you want to programmatically manipulate the postback, such as attaching it to other elements on the page. 可以设置Button控件的UseSubmitBehavior属性设置为true导致Button要使用客户端脚本控件基于回发。You can set the Button control's UseSubmitBehavior property to true to cause the Button control to use client-script based postback.

按钮控件和验证Button Controls and Validation

如果页面包含 ASP.NET 验证程序控件,默认情况下,单击一个按钮控件导致执行其检查验证程序控件。If a page contains ASP.NET validator controls, by default, clicking a button control causes the validator control to perform its check. 如果验证程序控件的启用了客户端验证,如果通过验证检查失败,则不提交页面。If client-side validation is enabled for a validator control, the page is not submitted if a validation check has failed.

下表介绍了使您能够更精确地控制验证过程的按钮控件支持的属性。The following table describes the properties supported by button controls that enable you to control the validation process more precisely.

属性Property 描述Description
CausesValidation 指定是否单击的按钮也执行验证检查。Specifies whether clicking the button also performs a validation check. 将此属性设置为false以防止验证检查。Set this property to false to prevent a validation check.
ValidationGroup 可以指定在单击该按钮时调用的页上的验证程序。Enables you to specify which validators on the page are called when the button is clicked. 如果不建立了任何验证组,单击按钮会调用所有页面上的验证程序。If no validation groups are established, a button click calls all of the validators that are on the page.

有关详细信息,请参阅在 ASP.NET 网页中验证用户输入For more information, see Validating User Input in ASP.NET Web Pages.

数据控件中的按钮Buttons in Data Controls

按钮 Web 服务器控件通常用于在数据控件中,例如中DataListGridView,和Repeater列表控件。Button Web server controls are often used in data controls, such as in the DataList, GridView, and Repeater list controls. 在这些情况下,您通常不响应直接到按钮单击事件。In those cases, you typically do not respond directly to the button click event. 相反,数据控件中的按钮将引发一个事件,是特定于数据控件。Instead, a button in a data control raises an event that is specific to the data control. 例如,在DataList控件中,一个按钮可能引发DataList控件的ItemCommand而不是引发的事件Button控件的Click事件。For example, in the DataList control, a button might raise the DataList control's ItemCommand event instead of raising the Button control's Click event.

由于数据绑定列表控件可以包含许多按钮,可以设置按钮的CommandArgument属性来指定要作为事件的一部分传递的值。Because data-bound list controls can contain many buttons, you can set the button's CommandArgument property to specify a value to pass as part of the event. 然后可以测试该参数以确定被单击的按钮。You can then test for this argument to see which button was clicked.

数据绑定到控件Binding Data to the Controls

可以在为了控制其属性设置将按钮 Web 服务器控件绑定到数据源动态。You can bind the button Web server controls to a data source in order to control their property settings dynamically. 例如,可以设置按钮的Text通过使用数据绑定的属性。For example, you can set a button's Text property by using data binding.

使用 UpdatePanel 控件的按钮Using Buttons with UpdatePanel Controls

在局部页面呈现使可能刷新不进行回发页面的部分。Partial-page rendering makes it possible to refresh portions of a page without a postback. UpdatePanel 控件使你能够将标记参与局部页面呈现的页面部分。UpdatePanel controls enable you to mark parts of the page that participate in partial-page rendering. 默认情况下,所包含的控件的行为UpdatePanel控制,包括Button控制,是执行异步回发而不是回发。By default, the behavior of controls inside an UpdatePanel control, including Button controls, is to perform an asynchronous postback instead of a postback. 这将刷新的内容UpdatePanel从回发所源自的控制。This refreshes only the contents of the UpdatePanel control from which the postback originates.

除了的方案Button内的控件UpdatePanel控件,可以使用Button控制与UpdatePanel控件在以下方案:In addition to the scenario of a Button control that is inside an UpdatePanel control, you can use Button controls with UpdatePanel controls in the following scenarios:
