呵呵，不是.NET的.
这几天论坛上回答问题，有人提出这个DataGrid控件的分页。
请看：
?
数据库：test2000.mdb
表：numbers
字段：Id(自动编号)，anumber(数字)
?
因为DataGrid控件我们采用直接绑定记录集来显示数据.所以分页处理我们采用了间接的办法，定义另一个记录集objrs，将分页后的记录集付给objrs.然后绑定DataGrid
'效果还不错 , 我加了详细地注释?像pagesize, AbsolutePage的用法可参考msdn
?
VB中新建工程,form中添加DataGrid控件,按钮cmdPrevious和cmdNext，文本框txtPage
