Question

我很难让gridview响应排序。通过这个论坛，我在http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.objectdatasource.sortparametername.aspx处遇到了一个MSDN示例。我复制并构建了代码，gridview显示正确，但在单击列标题对数据进行排序时没有响应。

由于某些原因，系统没有响应列标题点击，但对我的页面上的其他Web控件（如超链接和按钮）进行了正确响应。我想知道是否有需要配置的Visual Studio 2008设置，或者是否因为我在本地主机上运行它。似乎没有合理性，但我的想法已经用完了。
