介绍Introduction
DataPager类用于对数据进行分页,并为实现接口的数据绑定控件显示导航控件 IPageableItemContainer 。The DataPager class is used to page data and to display navigation controls for data-bound controls that implement the IPageableItemContainer interface. (实现接口的控件的一个示例是 ListView 控件。 ) (An example of a control that implements the interface is the ListView control.)
您可以 DataPager 使用属性将控件与数据绑定控件关联起来 PagedControlID 。You can associate the DataPager control with the data-bound control by using the PagedControlID property. 或者,您可以将控件放在 DataPager 数据绑定控件层次结构中。Alternatively, you can put the DataPager control inside the data-bound control hierarchy. 例如,在控件中 ListView ,可以将 DataPager 控件置于 ListView.LayoutTemplate 模板内。For example, in the ListView control, you can put the DataPager control inside the ListView.LayoutTemplate template.
通过更改属性,可以自定义为每个数据页显示的项目数 PageSize 。You can customize the number of items that are displayed for each page of data by changing the PageSize property. 还可以通过设置属性来更改向服务器提交页面的方式 QueryStringField 。You can also change the way a page is submitted to the server by setting the QueryStringField property.
页导航字段Pager Fields
为了使 DataPager 控件能够显示导航控件,必须将页导航字段添加到控件中。In order for the DataPager control to display navigation controls, you must add pager fields to the control. 页导航字段派生自 DataPagerField 类。The pager fields derive from the DataPagerField class. 下表列出了可以使用的页导航字段类型。The following table lists the pager field types that you can use.
| 页导航字段类型Pager field type | 说明Description |
|---|---|
| NextPreviousPagerField | 允许用户一次在页面上导航,或跳转到第一页或最后一页。Enables users to navigate through pages one page at a time, or to jump to the first or last page. |
| NumericPagerField | 允许用户按页码选择页。Enables users to select a page by page number. |
| TemplatePagerField | 使您能够创建自定义分页 UI。Enables you to create a custom paging UI. |
若要以声明方式向控件添加页导航字段 DataPager ,请将 Fields 元素添加到 DataPager 控件。To declaratively add pager fields to the DataPager control, add a Fields element to the DataPager control. 然后,可以将页导航字段添加到 Fields 元素。You can then add the pager fields to the Fields element. 页导航字段将 Fields 按照它们在元素中出现的顺序添加到集合中 Fields 。The pager fields are added to the Fields collection in the order that they appear in the Fields element. Fields集合使你能够以编程方式管理控件中的页导航字段 DataPager 。The Fields collection enables you to programmatically manage the pager fields in the DataPager control.
页面属性Page Properties
下表列出了 DataPager 控件的只读属性,这些属性指定了数据页的特性。The following table lists read-only properties of the DataPager control that specify characteristics of the page of data. 这些属性通常用于对象中的绑定表达式 TemplatePagerField 。These properties are usually used for binding expressions in the TemplatePagerField object.
| propertiesProperty | 说明Description |
|---|---|
| MaximumRows | 为每个数据页显示的最大记录数。The maximum number of records that are displayed for each page of data. |
| StartRowIndex | 在数据页上显示的第一条记录的索引。The index of the first record that is displayed on a page of data. |
| TotalRowCount | 基础数据源中可用的记录总数。The total number of records that are available in the underlying data source. |
可访问性Accessibility
此控件默认呈现的标记可能不符合辅助功能标准,例如 Web 内容辅助功能准则 1.0 (WCAG) 优先级1指导原则。The default markup that is rendered default for this control might not comply with accessibility standards, such as the Web Content Accessibility Guidelines 1.0 (WCAG) priority 1 guidelines. 有关此控件的辅助功能支持的详细信息,请参阅 ASP.NET 控件和辅助功能。For details about accessibility support for this control, see ASP.NET Controls and Accessibility.
