Private Sub DataGrid1_PageIndexChanged(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridPageChangedEventArgs) Handles DataGrid1.PageIndexChanged
Dim dtr As String
dtr = "select x.cname ,x.dnum,x.sn,x.proarea,x.spec,x.elesort,x.unitprice,x.instock,x.instocktime,x.attach," & _
"x.unit,x.transact,y.avgprice,y.totalprice,y.nowstock,x.rn from intable x,maintable y where x.dnum=y.dnum"
DataGrid1.DataSource = query(dtr)
' DataGrid1.CurrentPageIndex() = 0
DataGrid1.DataBind()
DataGrid1.CurrentPageIndex = e.NewPageIndex
DataGrid1.DataBind()
' selectbutton.Enabled = False
End Sub
query是字定义方法，连接数据库返回DATASET，肯定好用的！Top

可以自己在DataGrid1_ItemCommand的事件里面写，上面已经给出了例子。
你要是想做出个性化的datagrid,这个事件是要好好下点功夫研究研究的。Top

按钮列你给它一个CommandName
例如:<asp:ButtonColumn Text="选择" CommandName="select"></asp:ButtonColumn>
然后在DataGrid1_ItemCommand的事件里面写
例如:
private void DataGrid1_ItemCommand(...)
{
if(e.CommandName=="select")
{
//执行选择按钮列要完成的功能
}
}
这样的话翻页和按钮列就不会相互影响了Top
