ASP.NET Web窗体单选按钮

它是一个输入控件，用于接收用户的输入。它允许用户从选项组中选择一个选项。

要创建RadioButton，我们可以将其从Visual Studio的工具箱中拖动。

这是一个服务器端控件，ASP.NET提供了自己的标签来创建它。下面给出示例。

< asp:RadioButtonID="RadioButton1" runat="server" Text="Male" GroupName="gender"/>

服务器将其呈现为HTML控件，并向浏览器生成以下代码。

Male

该控件具有自己的属性，如下表所示。

例

在此示例中，我们将创建两个单选按钮，并放入一个名为“性别”的组。

// WebControls.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebControls.aspx.cs" 
Inherits="WebFormsControlls.WebControls" %>

背后的代码

// WebControls.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace WebFormsControlls
{
    public partial class WebControls : System.Web.UI.Page
    {
        protected void Button1_Click(object sender, EventArgs e)
        {
            genderId.Text = "";
            if (RadioButton1.Checked)
            {
                genderId.Text = "Your gender is "+RadioButton1.Text;
            }
            else genderId.Text = "Your gender is "+RadioButton2.Text;

        }
    }
}

对于此控件，我们设置了以下一些属性：
