我有处理网格的CellLeave事件.我已将对话框结果取消"设置为按钮.

当用户按下确定"按钮时，我想关闭表格.但是要在我写了一些验证代码的地方休假，所以我无法关闭表格.

``请告诉我如何检测按钮按下情况，我不希望电池离开.当我按下取消"按钮时，它应该直接关闭表单.

I have Datagridview control and "OK" Button control on form.

I have handle CellLeave event of grid. I have set dialog Result "Cancel" for button.

When user press "Ok" button I want to close form. but it is going to cell leave where I have written some validation code, so I am not able to close form.

''Please tell me how can i detect button press , I dont want cell leave to fire. When I press Cancel button , It should directly close form.

推荐答案

您可以从CellLeave事件中删除处理程序，但是我会有一个类级别的布尔IsClosing在Click处理程序中进行设置，然后对其他所有内容进行测试.

You could remove the handler from the CellLeave Event, but I would have a class level bool IsClosing which I set in the Click handler and test in everything else. It''s a lot clearer, and very simple to implement.

要解决此问题，只需将验证码从CellLeave事件移到ButtonOK_Click事件.

To resolve this problem, just move validation-code from CellLeave event into ButtonOK_Click event.
