验证单选按钮 [英] Validation for radio buttons

问题描述

我是使用c#的asp.net的初学者. .

在我的项目中，我使用了一个带有Input(Radio)的gridview控件.如果我选择了1个单选按钮，则单击选择"(它是一个按钮).然后，所选的单选按钮详细信息将显示在以下文本框中.然后我可以对其进行修改并将其存储..

我的问题是假设用户如果不选择单选按钮，则直接单击选择按钮，而不在网格视图中选择单选按钮，就会发生错误.

然后我的问题是如何为该按钮单击设置验证.

请帮助我..我不知道..是对还是错..

您可以使用javascript函数检查

You can use javascript function to check

function GetRadioButtonValue(id)
{
    var radio = document.getElementsByName(id);
    for (var j = 0; j < radio.length; j++)
    {
        if (radio[j].checked)
            alert(radio[j].value);
    }
}
