问题描述

我想在第二次单击时取消选中(单选按钮). (例如，我单击一次，它会打一个勾号-我再次单击它会删除它).

I want to uncheck a (radio button) on the 2nd click. (e.g. I click once, it puts a check mark - I click a second time, it removes it).

推荐答案

嗨
您可以使用相同的复选框.为什么要使用单选按钮.有任何特定要求吗，请在这里告诉我们.

Hi
you can use check box for same. why you want to use radio button for same. is there any specific requirement then please let us know here.

这将滥用众所周知的预期UI行为.正如Keyur Satyadev正确指出的那样，这是一个复选框行为(已可用).

(即使有人需要这样的东西，您的责任是拒绝它，解释为什么要这样做-沟通并调节情况.发生这种情况.)

This would be abuse of well-known and expected UI behavior. As Keyur Satyadev correctly put it, it''s a check box behavior (already available).

(Even is somebody required something like that, your responsibility is to deny it, explain why it should be done -- communicate and regulate the situation. Such things happen.)

我会建议您使用Checkbox控件，您可以在其中实际执行所要求的操作.
但是单选按钮只是您要使用的参考以下代码:

I will suggest you to use Checkbox control where you can actually do what you have asked.
But radio button is only that you want to use refer following code :

bool blnState;

public Form1()
{
    InitializeComponent();
}

private void radioButton1_MouseDown(object sender, MouseEventArgs e)
{
    blnState = radioButton1.Checked;
}

private void radioButton1_MouseUp(object sender, MouseEventArgs e)
{
    radioButton1.Checked = !blnState;
}

其中radioButton1是您正在使用的单选按钮的名称.
我已经使用了此控件的mousedown和mouseup事件.

where radioButton1 is the name of the radio button that you are using.
I have used the mousedown and mouseup events of this control.
