下面的代码示例演示如何在一页上Repeater使用两个简单控件。The following code example demonstrates how to use two simple Repeater controls on a page. 属性用于指定Repeater控件的数据源。 DataSourceThe DataSource property is used to specify the data source for the Repeater control. 第一Repeater种是在表中显示其项; Repeater第二种是以逗号分隔的列表显示其项。The first Repeater displays its items in a table; the second Repeater displays its items in a comma-separated list.

介绍Introduction

Repeater控件是一个基本的模板化数据绑定列表。The Repeater control is a basic templated data-bound list. 它没有内置布局或样式,因此必须在控件的模板中显式声明所有布局、格式和样式标记。It has no built-in layout or styles, so you must explicitly declare all layout, formatting, and style tags within the control's templates.

Repeater控件允许您在模板中拆分标记标记。The Repeater control allows you to split markup tags across the templates. 若要使用模板创建表,请在中包含开始表<table>标记() HeaderTemplate、中ItemTemplate的单个表行标记<tr>()和中FooterTemplate的结束表标记(</table>)。To create a table using templates, include the begin table tag (<table>) in the HeaderTemplate, a single table row tag (<tr>) in the ItemTemplate, and the end table tag (</table>) in the FooterTemplate.

Repeater控件没有内置的选定功能或编辑支持。The Repeater control has no built-in selection capabilities or editing support. 可以使用ItemCommand事件处理从模板引发的控件事件到控件。You can use the ItemCommand event to process control events that are raised from the templates to the control.

注意

此控件可用于显示用户输入,其中可能包括恶意客户端脚本。This control can be used to display user input, which might include malicious client script. 在应用程序中显示可执行脚本、SQL 语句或其他代码之前,请检查从该客户端发送的任何信息。Check any information that is sent from a client for executable script, SQL statements, or other code before displaying it in your application. ASP.NET 提供输入请求验证功能来阻止用户输入中的脚本和 HTML。ASP.NET provides an input request validation feature to block script and HTML in user input. 还提供验证服务器控件以评估用户输入。Validation server controls are also provided to assess user input. 有关详细信息,请参阅验证服务器控制语法For more information, see Validation Server Control Syntax.

数据绑定Data Binding

Repeater控件提供了两个属性来支持数据绑定。The Repeater control provides two properties to support data binding. 若要将数据绑定System.Collections.IEnumerable到实现接口的任何集合(如System.Data.DataViewSystem.Collections.ArrayList或数组DataSource )或IListSource接口,请使用属性来指定数据源。To bind data to any collection that implements the System.Collections.IEnumerable interface (such as a System.Data.DataView, a System.Collections.ArrayList, or an array), or the IListSource interface, use the DataSource property to specify the data source. 设置DataSource属性时,必须手动编写代码以执行数据绑定。When you set the DataSource property, you must manually write the code to perform data binding. 若要自动将Repeater控件绑定到数据源控件所表示的数据源,请DataSourceID将属性设置为ID要使用的数据源控件的。To automatically bind the Repeater control to a data source represented by a data source control, set the DataSourceID property to the ID of the data source control to use. 设置DataSourceID属性时Repeater ,控件将自动绑定到第一个请求上的指定数据源控件。When you set the DataSourceID property, the Repeater control automatically binds to the specified data source control on the first request. 因此,您无需显式调用DataBind方法,除非您已更改Repeater控件的数据相关属性。Therefore, you do not need to explicitly call the DataBind method unless you have changed data-related properties of the Repeater control.

ItemTemplate DataSource控件将其DataSourceIDAlternatingItemTemplate绑定到由其属性或其属性指定的数据源控件声明和引用的数据模型。 RepeaterA Repeater control binds its ItemTemplate and AlternatingItemTemplate to either the data model declared and referenced by its DataSource property or the data source control specified by its DataSourceID property. HeaderTemplate、和不SeparatorTemplate是数据绑定的。 FooterTemplateThe HeaderTemplate, FooterTemplate, and SeparatorTemplate are not data-bound.

如果已设置HeaderTemplate FooterTemplate控件的数据源但未返回任何数据,则该控件将呈现和,而不会显示任何项。 RepeaterIf the Repeater control's data source is set but no data is returned, the control renders the HeaderTemplate and FooterTemplate with no items. 如果数据源为null Repeater ,则不会呈现。If the data source is null, the Repeater is not rendered.

模板Templates

每个Repeater控件至少必须定义一个ItemTemplateAt a minimum, every Repeater control must define an ItemTemplate. 不过,下表中所述的其他可选模板可用于自定义列表的外观。However, other optional templates described in the following table can be used to customize the appearance of the list.

模板名称Template name 说明Description
ItemTemplate 定义列表中项的内容和布局。Defines the content and layout of items within the list. 此模板是必需的。This template is required.
AlternatingItemTemplate 如果已定义,则确定交替(从零开始的奇数索引)项的内容和布局。If defined, determines the content and layout of alternating (zero-based odd-indexed) items. 如果未定义, ItemTemplate则使用。If not defined, ItemTemplate is used.
SeparatorTemplate 如果已定义,则在项(和交替项)之间呈现。If defined, is rendered between items (and alternating items). 如果未定义,则不会呈现分隔符。If not defined, a separator is not rendered.
HeaderTemplate 如果已定义,则确定列表标题的内容和布局。If defined, determines the content and layout of the list header. 如果未定义,则不会呈现标头。If not defined, a header is not rendered.
FooterTemplate 如果已定义,则确定列表脚注的内容和布局。If defined, determines the content and layout of the list footer. 如果未定义,则不会呈现脚注。If not defined, a footer is not rendered.
