DataGrid 添加 RadioButton_综合

晕哦，我刚写的没了。。。。重写

看到很多人用了好多办法写这个功能，我好久没用了，也忘了怎么写的，不过看着挺麻烦的，有个老外重写了RadioButton, 我这个类似重写DataGrid, 其实不管radiobutton还是radiobuttonlist都是让它实现单选并显示在datagird的列中，前者是在单选上写JS控制它的name,后者是在显示上写JS让它显示在DataGrid上，我选了后者，有兴趣的可以把我这个重写DataGrid。有篇类似文章，不过代码不全没看明白：http://blog.csdn.net/j99616/archive/2003/09/02/19247.aspx

有用的朋友可以copy-paste一下，感觉我的比较简单一点，找了半天没找到好用的。。。。。。

aspx上：

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

<! DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >
< html xmlns ="http://www.w3.org/1999/xhtml" >
< head runat ="server" >
     < title > Untitled Page </ title >
</ head >
< body >
     < form id ="form1" runat ="server" >
         < asp:RadioButtonList ID ="rbl" runat ="server" AutoPostBack ="True" OnSelectedIndexChanged ="rbl_SelectedIndexChanged" >
         </ asp:RadioButtonList >
         < asp:DataGrid ID ="DataGrid1" runat ="server" OnItemCreated ="DataGrid1_ItemCreated" >
         </ asp:DataGrid >
     </ form >

     < script >
   var dg=document.getElementById("<%=DataGrid1.ClientID %>");
   var rb=document.getElementById("<%=rbl.ClientID %>");
   for(var i=1;i<=dg.rows.length-1;i++)
   {
        dg.rows[i].cells[0].innerHTML=rb.rows[i-1].cells[0].innerHTML;
        rb.rows[i-1].cells[0].innerHTML="";
   }
     </ script >

</ body >
</ html >

cs文件：

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        bind();
    }

    protected void bind()
    {
        string[] s ={ "1", "2", "3" };
        DataGrid1.DataSource = s;
        DataGrid1.DataBind();
    }

    protected void DataGrid1_ItemCreated(object sender, DataGridItemEventArgs e)
    {
        TableCell tc = new TableCell();
        tc.Width = Unit.Parse("40");
        e.Item.Cells.AddAt(0, tc);
        if (e.Item.ItemIndex != -1 && !IsPostBack)
        {
            ListItem li = new ListItem("", e.Item.ItemIndex.ToString());
            rbl.Items.Add(li);
        }
    }

    protected void rbl_SelectedIndexChanged(object sender, EventArgs e)
    {
        Response.Write(rbl.SelectedValue);//这里就是radiobuttionlist选中项的值，目前是行标，你可以在ItemCreated的时候赋其他值
    }
}

代码还是用自已写的比较好。。。。。。。。
