注解

如果网页上有多个 LinkButton 控件,请使用 CommandName 属性来指定或确定与所单击 LinkButton 控件关联的命令名。When you have multiple LinkButton controls on a Web page, use the CommandName property to specify or determine the command name associated with the LinkButton control clicked. 可以将 CommandName 属性设置为任何标识要执行的命令的字符串。You can set the CommandName property with any string that identifies the command to perform. 然后,你可以通过编程方式确定 LinkButton 控件的命令名称并执行适当的操作。You can then programmatically determine the command name of the LinkButton control and perform the appropriate actions.

可以通过使用 CommandArgument 属性指定有关命令的其他信息,如 Ascending 排序顺序。Additional information about the command, such as an Ascending sort order, can be specified by using the CommandArgument property.

无法通过主题或样式表主题设置此属性。This property cannot be set by themes or style sheet themes. 有关详细信息,请参阅 ThemeableAttributeASP.NET 主题和外观For more information, see ThemeableAttribute and ASP.NET Themes and Skins.
