1.您需要使用此示例中显示的数据网格的CurrentRow

1. You need to use the datagrid''s CurrentRow as shown in this sample

Textbox1.text = datagridview1.currentrow.cells(i).value
'where i is the poistion in the row that you want get out

关于2，到目前为止，您还没有提供有关如何处理数据的任何详细信息?您正在使用数据层吗? tableadapters?

in regards to 2 you haven''t given any details on how your handling your data so far? are you using a datalayer? tableadapters?

使用分页在DataGridView中添加，编辑和删除 [^ ]
检查一下，自己尝试尝试一下，如果卡在某个地方，然后再找回.

Add, Edit, and Delete in DataGridView with Paging[^]
Check this out, try something on your own, and then get back if you are stuck somewhere.
