问题描述

在我的c#应用程序中,我需要radiobutton,但是如果用户单击一个单选按钮,他们就无法取消它们(所以一旦他们选择了它,它就成为强制性的)。我无法取消它们。有人会提出这个想法吗?

In my c# application, I need radiobutton, but if the user clicks a radio button they can't unclick them (so it becomes mandatory once they've chosen one). I can not unclick them. can some one give the idea?
