初学.Net，问题可能很白痴，希望大家来帮忙！问题是response.aspx中的button控件如何可以点击后触发.cs文件里的btnOK_Click事件。点击按钮没有起作用。还有一个问题就是form的action为什么改不掉呢，修改控件里的action属性也改不掉。没搞明白，代码如下：

这是response.aspx中的控件代码：

  <div>
       <form id="Form1" method="post" runat="server" action="~/chapter2/welcom.aspx">
        姓名：<asp:TextBox ID="txtName" runat="server"></asp:TextBox>
        <br />
        性别：<asp:RadioButton ID="rbtSex1" runat="server" Checked="True" Text="男" GroupName="sex" />
              <asp:RadioButton ID="rbtSex2" runat="server" Text="女" GroupName="sex" />
        <br />
        <asp:Button ID="btnOK" runat="server" Text="确定"/>
        </form>
    </div>

这是cs文件里的代码

        {
            Response.Write("<h1>在页面中输出数据</h1>");
            char c = 'a';//定义一个字符变量
            string s = "Hello World!";//定义一个字符串变量
            char[] cArray={'H','e','l','l','o',',','W','o','r','l','d'};//定义一个字符数组
            Page p = new Page();//定义一个Page对象
            Response.Write("输出单个字符");
            Response.Write(c);
            Response.Write("<br />");
            Response.Write("输出一个字符串"+s+"<br />");
            Response.Write("输出字符数组");
            Response.Write(cArray, 0, cArray.Length);
            Response.Write("<br />");
            Response.Write("输出一个对象");
            Response.Write(p);
            Response.Write("<br />");
            Response.Write("输出一个文件");
            Response.Write(@"D:\dotnet\WebApplication1\WebApplication1\chapter2\WriteFile.txt");//读取不出来
            Response.Write("<h1>页面跳转并传递参数</h1>");
        }

        protected void btnOK_Click(object sender, EventArgs e)
        {

            string name = this.txtName.Text;
            string sex = "先生";
            if (this.rbtSex2.Checked)
                sex = "女士";
            Response.Redirect("welcom.aspx");
       
        }
    }
