选中并取消选中RadioButton [英] check and uncheck RadioButton

问题描述

我希望能够选中/选择一个单选按钮，然后取消选中/取消选中(如果他们偶然选择了错误的文件).

I would like to be able to check/select a radiobutton and then uncheck/deselect(if they select the wrong filed by chance) . Is there a way to do this in asp.net?

推荐答案

我建​​议您使用Checkbox控件在实际可以执行要求的地方进行操作. > 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.

您能解释清楚吗?

我认为，这对您使用单选按钮列表并选择True为true很有帮助.

i think, this is help u use Radio Button List and Select Autopostback true.

您是否在谈论

Are you talking about OnCheckedChanged event[^]

As said by Vinoth you need to set autopostback property to true.
