ListControl 类

定义

用作定义所有列表类型控件通用的属性、方法和事件的抽象基类。Serves as the abstract base class that defines the properties, methods, and events common for all list-type controls.

public ref class ListControl abstract : System::Web::UI::WebControls::DataBoundControl, System::Web::UI::IEditableTextControl
[System.Web.UI.ControlValueProperty("SelectedValue")]

示例

下面的代码示例演示如何在ListBox控件中选择项。The following code example demonstrates how to select items in a ListBox control. 如果在文本框中找到该项,则选择该项并显示一条消息,其中显示了所选项的名称。If the item is found in the text box, the item is selected and a message is displayed stating the name of the selected item. 如果找不到该项,则不选择任何项,并显示一条消息,指出找不到该项。If the item is not found, no item is selected and a message is displayed stating that the item was not found.

重要

此示例具有一个接受用户输入的文本框,这是一个潜在的安全威胁。This example has a text box that accepts user input, which is a potential security threat. 默认情况下,ASP.NET 网页验证用户输入是否不包含脚本或 HTML 元素。By default, ASP.NET Web pages validate that user input does not include script or HTML elements. 有关详细信息,请参阅脚本侵入概述For more information, see Script Exploits Overview.

注解

不能直接创建ListControl抽象类的实例。An instance of the ListControl abstract class cannot be created directly. 相反,此类由其他类( CheckBoxList如、 DropDownListListBoxRadioButtonList类)继承,以提供常见的基本功能。Instead, this class is inherited by other classes, such as the CheckBoxList, DropDownList, ListBox, and RadioButtonList classes, to provide common basic functionality.

ListControl类的属性允许您指定数据源以填充列表控件。The properties of the ListControl class allow you to specify the source of the data to populate the list control. DataSource使用属性指定要绑定到列表控件的数据源。Use the DataSource property to specify the data source to bind to the list control. 如果数据源包含多个表,则使用DataMember属性指定要使用的表。If the data source contains more than one table, use the DataMember property to specify the table to use. 通过分别设置ListItem.Text DataTextFieldListItem.Value 属性DataValueField ,可以将数据源中的不同字段绑定到列表控件中的项的和属性。You can bind different fields in the data source to the ListItem.Text and ListItem.Value properties of the items in the list control by setting the DataTextField and DataValueField properties, respectively. 为列表控件中的每一项显示的文本可以通过设置DataTextFormatString属性来设置格式。The text displayed for each item in the list control can by formatted by setting the DataTextFormatString property.

列表控件中显示的所有项均存储在Items集合中。All items displayed in the list control are stored in the Items collection. 通过使用SelectedIndex属性,可以以编程方式指定或确定列表控件中选定项的索引。You can programmatically specify or determine the index of a selected item in the list control by using the SelectedIndex property. 可以通过使用SelectedItem属性访问选定项的属性。The properties of the selected item can be accessed by using the SelectedItem property.

ListControlSelectedIndexChanged提供事件,该事件在列表控件中的选定内容在向服务器的各次发送之间发生更改时引发。The ListControl class provides the SelectedIndexChanged event, which is raised when the selection in the list control changes between posts to the server. 这允许您为此事件提供自定义处理程序。This allows you to provide a custom handler for this event. 有关如何处理事件的详细信息,请参阅处理和引发事件For more information about how to handle events, see Handling and Raising Events.

ListControlIEditableTextControl实现接口,以便可以在其他控件的模板模式下使用派生的列表类型控件。The ListControl class implements the IEditableTextControl interface so that derived list-type controls can be used in the template mode of other controls.
