vb.net - DataGridView EndEdit VB

Question

现在，我在离开 EventArgs 中使用 EndEdit，但是当我使用 EndEdit 时，我无法关闭我的表单。有谁知道原因？

以下是我的休假功能：

 Private Sub dgv_Leave(ByVal sender As System.Object, 
                       ByVal e As System.EventArgs) Handles dgv.Leave
            Me.dgv.EndEdit()
    End Sub

Answer 1

这可能是由于 DataGridView 中可能存在一些验证错误。您必须检查是否dataGridView.EndEdit()成功，并且您可能还需要检查您的 Cell 和 RowValidating 事件（如果存在）。

Answer 2

我找到了解决 EndEdit 问题的解决方案。然后，我可以正确结束编辑，并且可以成功关闭我的表单。
