RepeatLayout	Table\|Flow	展現(xiàn)方式：表格\|流線型

二、代碼演示

前臺 RadioButtonList.aspx

復制代碼代碼如下:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="RadioButtonList.aspx.cs" Inherits="WebControls_RadioButtonList" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "
<html xmlns=" <head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <h3>RadioButtonList（單選按鈕組）</h3>
        <hr />
        請選擇性別：<asp:RadioButtonList
            ID="radlSex" runat="server" RepeatDirection="Horizontal" RepeatLayout="Flow">
            <asp:ListItem Selected="True">男</asp:ListItem>
            <asp:ListItem>女</asp:ListItem>
        </asp:RadioButtonList>
        <br />
        <asp:Button ID="btnSubmit" runat="server" Text="提交" onclick="btnSubmit_Click" />
        <hr />
        你選擇的性別為：<asp:Label ID="lblState" runat="server"></asp:Label>

    </div>
    </form>
</body>
</html>

后臺 RadioButtonList.aspx.cs

復制代碼代碼如下:

using System;

using System.Collections.Generic;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

public partial class WebControls_RadioButtonList : System.Web.UI.Page

{

    protected void Page_Load(object sender, EventArgs e)

    {

    }

    protected void btnSubmit_Click(object sender, EventArgs e)

    {

        lblState.Text = radlSex.SelectedValue;

    }

}
