推荐答案

调用您在pageload的！ispostback中的bindGrid方法看到网格绑定是否完全完成了吗?绑定网格时应该存在问题，一个或多个列一定不能绑定到网格，然后碰巧数据集将具有3行，但绑定后没有网格...

call Your bindGrid method in !ispostback of pageload and see is the grid binding completely??? there should be problem in binding grid one or more column must not be binded to grid then it happends dataset would have 3 rows but not grid have after binding...
