在datagrid外设置一个按钮（button3）
sub button3(sender as object, e as eventargs)
dim _item as datagrid.item
dim i as integer
for i=0 to datagrid1,items.count-1
_item=datagrid.items(i)
dim thecontent as textbox=_item.findcontrol("content") //content为textbox的id
next
end sub
sub button3(sender as object, e as eventargs)
dim _item as datagrid.item
dim i as integer
for i=0 to datagrid1,items.count-1
_item=datagrid.items(i)
dim thecontent as textbox=_item.findcontrol("content") //content为textbox的id
next
end sub
用这个方法肯定不行！
