本例實現通過RadioButton對DataList控件進行單選。你可以參考下面演示。

通過RadioButton對DataList控件進行單選實例說明

準備好一個星座對象，并定義好一個泛型List來存儲每一個星座名稱。

復制代碼代碼如下:

Constelltion.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
/// <summary>
/// Summary description for Constellation
/// </summary>
namespace Insus.NET
{
public class Constellation
{
private int _ID;
private string _Name;
public int ID
{
get { return _ID; }
set { _ID = value; }
}
public string Name
{
get { return _Name; }
set { _Name = value; }
}
public Constellation()
{
//
// TODO: Add constructor logic here
//
}
public Constellation(int id, string name)
{
this._ID = id;
this._Name = name;
}
public List<Constellation> GetConstellation()
{
List<Constellation> constellation = new List<Constellation>();
Constellation c = new Constellation(1, " 白羊座");
constellation.Add(c);
c = new Constellation(2, "金牛座");
constellation.Add(c);
c = new Constellation(3, "雙子座");
constellation.Add(c);
c = new Constellation(4, "巨蟹座");
constellation.Add(c);
c = new Constellation(5, "獅子座");
constellation.Add(c);
c = new Constellation(6, "處女座");
constellation.Add(c);
c = new Constellation(7, "天秤座 ");
constellation.Add(c);
c = new Constellation(8, "天蝎座");
constellation.Add(c);
c = new Constellation(9, "射手座");
constellation.Add(c);
c = new Constellation(10, "摩羯座");
constellation.Add(c);
c = new Constellation(11, "水瓶座");
constellation.Add(c);
c = new Constellation(12, "雙魚座");
constellation.Add(c);
return constellation;
}
}
}

在.aspx拉一個DataList控件，把RadioButton置于DataList的ItemTemplate模版內。

復制代碼代碼如下:

<asp:DataList runat="server" CellPadding="0" CellSpacing="0">
<ItemStyle BorderWidth="1" />
<ItemTemplate>
<table>
<tr>
<td>
<asp:RadioButton runat="server" /></td>
<td><%# Eval("ID") %></td>
<td><%# Eval("Name") %></td>
</tr>
</table>
</ItemTemplate>
</asp:DataList>

在.aspx.cs內為DataList控件綁定數據：

復制代碼代碼如下:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Insus.NET;
public partial class _Default : System.Web.UI.Page
{
Constellation objConstellation = new Constellation();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
Data_Binding();
}
private void Data_Binding()
{
this.DataListConstellation.DataSource = objConstellation.GetConstellation();
this.DataListConstellation.DataBind();
}
}
