buttoncolumn问题，在各大论坛问了好几天了，还是解决不了，只有50分了

我在datagrid控件里有一个buttoncolumn，在它的OnItemCommand事件中
Sub DataGrid_ItemCommand(Sender As object,E as DataGridCommandEventArgs)
dim strNum as string=e.item.cells(1).text
lblShowText.Textt=strNum
End Sub
在没有按datagrid控件的上一页，下一页时候，它是运行正常的（即可以准确获得预定的值），但当我按“下一页”时就出现以下错误了：
指定的参数已超出有效值的范围。参数名：index
出错行:dim strNum as string=e.item.cells(1).text
不知道为什么会这样，请各位高手赐教了！万分感谢

datagrid的页是从0开始的
返回给你的页数是从1 开始的

你没有判断DataGridItem的类型，不会写vb.net的代码，把你的改成C#的：

void DataGrid_ItemCommand(object Sender,DataGridCommandEventArgs e){
if(e.Item.ItemType==ListItemType.Item||e.Item.ItemType==ListItemType.AlternatingItem){
string strNum=e.Item.Cells[1].Text;
}
}

这个的分页应该没有问题
因为我把这个OnItemCommand事件的代码去掉，分页就一点问题都没有

[saucer]

because when you click on "下一页", ItemComamnd is also triggered and e.Item is refers to the Pager(?), so you should give the button a command name and check for its value in your ItemCommand

<asp:ButtonColumn CommandName="MyButton" ...


Sub DataGrid_ItemCommand(Sender As object,E as DataGridCommandEventArgs)
If CType(e.CommandSource, Button).CommandName = "MyButton" Then 'or
'If CType(e.CommandSource, LinkButton).CommandName = "MyButton" Then
dim strNum as string=e.item.cells(1).text
lblShowText.Textt=strNum
end if
End Sub
