DataGridPagerStyle 类

项目
08/17/2007

指定 DataGrid 控件的页导航的样式。无法继承此类。

**命名空间:**System.Web.UI.WebControls
**程序集:**System.Web（在 system.web.dll 中）

语法

声明
Public NotInheritable Class DataGridPagerStyle
    Inherits TableItemStyle
用法
Dim instance As DataGridPagerStyle

public sealed class DataGridPagerStyle : TableItemStyle

public ref class DataGridPagerStyle sealed : public TableItemStyle

public final class DataGridPagerStyle extends TableItemStyle

public final class DataGridPagerStyle extends TableItemStyle

备注

页导航是 DataGrid 控件上的元素，使您可以在启用分页时链接到其他页。DataGrid 控件的 PagerStyle 属性使用此类的实例来表示页导航的样式属性。

有关分页的更多信息，请参见 AllowPaging 和 AllowCustomPaging。

示例

下面的代码示例演示如何使用 DataGridPagerStyle 对象来表示 PagerStyle 属性中页导航元素的样式。DataGridPagerStyle 对象设置分页元素的显示模式和对齐方式。
