Vb.net(Win) DataGirdView DataTable There is no current data to access

这个error出现是因为你处理delete方面不当
delete的时候需要用orginal
arrl_Parameters.Add(New SqlParameter("@XX", dataRow("XX", DataRowVersion.Original)))
需要整理什么时候用current，什么时候使用original
arrl_Parameters.Add(New SqlParameter("@XX", dataRow("XX", DataRowVersion.Current)))

Insert时可以使用current
If xRow.RowState = DataRowState.Added Then
arrl_Parameters.Add(New SqlParameter("@XX", dataRow("XX", DataRowVersion.Current)))

Update时可以使用original，当ID不能更改
ElseIf xRow.RowState = DataRowState.Modified Then
arrl_Parameters.Add(New SqlParameter("@XX", dataRow("XX", DataRowVersion.Original)))

Delete时肯定要用original
ElseIf xRow.RowState = DataRowState.Deleted Then
arrl_Parameters.Add(New SqlParameter("@XX", dataRow("XX", DataRowVersion.Original)))
