{“无法删除未提交的新行。”} System.InvalidOperationException

如果我将继续并运行我的代码并在我的数据网格中写入一个新行，我将再次尝试初始化（现在我有两行，一个有数据，另一个是空的）我接受这个错误
{"Uncommitted new row cannot be deleted."} System.InvalidOperationException
{“无法删除未提交的新行。”} System.InvalidOperationException
I can't solve it, Please is there someone to assist me on that?

If Not DGV.Rows(i).IsNewRow Then
DGV.Rows.RemoveAt(i)
End If
Add this condition to your loop. Alternatively, you could also use DGV.RejectChanges() which will reset all the row status to original.
将此条件添加到您的循环中。或者，您也可以使用 DGV.RejectChanges() 将所有行状态重置为原始状态。

If your goal is to empty the row collection, you can just use the Clear method of the Rows collection:
如果您的目标是清空行集合，则可以使用 Rows 集合的 Clear 方法：
DGV.Rows.Clear()
DGV.Rows.Clear()
Hope this helps.
希望这可以帮助。
