asp.net ajax 的一个问题，高手请进...

我想实现 像迅雷看看那样，在播放电影的情况下 点击 左侧的“喜剧” 便可以在页面上长生一个层 ，而且这个层肯定接受了一个参数 所以层中才会显示 “喜剧“的内容。我初步设想用 asp.net ajax中的 modalPopup 扩展框，可是发现无法传递参数进去，谢谢大家帮帮我改如何做？

  1.   

    用datalist里嵌套GridView也可以啊，不过要配合脚本，默认隐藏GridView，点击以后触发脚本方法，展开GridView。
      

  2.   

    不知道迅雷的界面是怎样的。不过，我从来不使用asp.net ajax toolkit，我不太愿意用它（如果真的需要很好的客户端编程我建议你使用asp.net的<asp:Silverlight>控件并且使用silverlight编程）。下面我贴一个以前在csdn上贴过的demo，你可以在你的ajax enabled网站上创建一个aspx，然后把下面的内容覆盖到aspx上，看看结果<%@ Page Language="C#" %><script runat="server">   
        protected void Button2_Click(object sender, EventArgs e)
        {
            this.TextBox1.Text = this.TextBox3.Text + " 被后台处理";
            this.TextBox2.Text = DateTime.Now.ToLongTimeString() + " 被后台处理";
            this.Label2.Text = this.DropDownList2.SelectedValue;
            UpdatePanel3.Update();
            this.Panel1.Visible = false;
        }    protected void Button1_Click(object sender, EventArgs e)
        {
            this.Panel1.Visible = true;
            this.Label3.Text = TextBox4.Text;
        }    protected void 省修改了(object sender, EventArgs e)
        {
            this.DropDownList2.Items.Clear();
            switch (this.DropDownList1.SelectedValue)
            {
                case "北京":
                    this.DropDownList2.Items.Add("小张");
                    this.DropDownList2.Items.Add("老王");
                    this.DropDownList2.Items.Add("狗剩");
                    this.DropDownList2.Items.Add("浑沌");
                    this.DropDownList2.Items.Add("甜甜");
                    break;
                case "上海":
                    this.DropDownList2.Items.Add("柠檬");
                    this.DropDownList2.Items.Add("城隍庙");
                    this.DropDownList2.Items.Add("外滩");
                    break;
            }

    看看如何编程处理事件，相信你会在第一时间写出实用的程序，以后再慢慢改进。

    什么叫发现"无法传递参数进去"?
    页面加一个ModalPopupExtender
    加一个Panel,Panel中放GridView或DataList,
    GridView或DataList的数据来自" 点击 左侧的“喜剧”的id,
    这路子很正宗呵,哪来什么"无法传递参数进去"!!!
