注解

HtmlForm控件是 Web 窗体页上的服务器控件的容器。The HtmlForm control is a container for server controls on a Web Forms page. 回发到服务器的所有服务器控件都必须放置在控件的开始标记和结束标记之间 HtmlFormAll server controls that post back to the server must be placed between the opening and closing tags of an HtmlForm control.

备注

ASP.NET 仅允许 HtmlForm 在 Web 窗体页上激活单个控件。ASP.NET allows only a single HtmlForm control to be active on a Web Forms page. 如果 HtmlForm Web 窗体页上有多个活动控件,则 System.Web.HttpException 当您请求该页时,公共语言运行时将引发异常。If there is more than one active HtmlForm control on a Web Forms page, the common language runtime will throw an System.Web.HttpException exception when you request the page. 但是,可以使用 MultiView 控件,其中每个 View 对象都包含一个 HtmlForm 控件,因为 View 在任何给定时间只有一个对象处于活动状态。You can, however, use a MultiView control where each View object contains one HtmlForm control, because only one View is active at any given time.

可以 HtmlForm 通过设置控件的属性来控制控件的行为。You can control the behavior of the HtmlForm control by setting its properties. 若要为窗体数据指定编码类型,请设置 Enctype 属性。To specify the encoding type for the form's data, set the Enctype property. GET POST 浏览器用来将表单数据发布到服务器以进行处理的方法 (或) 通过设置属性来指定 MethodThe method (GET or POST) that a browser uses to post form data to the server for processing is specified by setting the Method property.

注意

默认情况下,Method 属性设置为 POSTBy default, the Method property is set to POST. 您可以将此属性的值修改为 GET ,但这可能会破坏 ASP.NET 页框架提供的内置状态和回发服务。You can modify the value of this property to GET, but this might break the built-in state and postback services provided by the ASP.NET page framework.

可以将实现接口的控件配置 IButtonControl 为发布到不同的目标页。You can configure controls that implement the IButtonControl interface to post to a different target page. 这称为跨页发送。This is referred to as cross-page posting. 有关详细信息,请参阅 ASP.NET Web Forms 中的跨页面发布For more information, see Cross-Page Posting in ASP.NET Web Forms.
