C＃：WinForm容器焦点事件

Question

I'm making a Windows Form as seen below. When I click on a row in the DataGridView , the details of a person is transferred unto the TextBoxes at the side. When the user click the Edit button,the entire Panel to the right becomes editable; the TextBoxes and CheckBoxes are Enabled and allows the users to edit a person's name, birthday, etc. After which, the changes are saved to the database. I don't want the user to click a different row while editing and thus want to detect when a user leaves the Panel so I can prompt him/her.

How do I detect if I've lost focus of the Panel ? If I'm going about this wrong, please respond with the appropriate answer instead.

也许当用户开始在Panel编辑记录时，可以将DataGridView的Enabled属性设置为False ，而当按下Save按钮时，可以再次将Enabled属性设置为True 。
