Gridview+SqlDataSource+分页+搜索[转载]
转自http://blog.csdn.net/ccp5780199/archive/2008/04/28/2337660.aspx
ASP.Net 2.0 中直接GridView加SqlDataSource 实现增删改的文章网上非常多了,这里就不重复了。
GridView + SqlDataSource 分页也很简单,直接点GridView的智能标示,然后启用分页。
加上搜索条件的话其实也不难,主要是要在GridView生成之前先设置好数据源。
否则就会导致点击其他分页又重新绑定了原始数据。
很简单,在这里我是利用GridView的PreRender事件,这个事件是在控件生成之前触发的,在这个事件里设置好SQL语句即可。
假设以Northwind为示例
