关于checkbox无法保存其状态的有关问题

关于checkbox无法保存其状态的问题
这个这个问题是刚才一个关于cookie的帖子的问题的延伸，还是另外发帖吧
一个登录的窗体，有一个checkbox，用来选择是否保存用户名密码，一个button用来提交

C# code

protected void Page_Load(object sender, EventArgs e)    {                if (Request.Cookies["travians"] != null)        {            TextBox1.Text = Request.Cookies["travians"]["userid"];            TextBox2.Text = Request.Cookies["travians"]["userpwd"];            CheckBox1.Checked = true;        }        else        {            CheckBox1.Checked = false;        }        if (IsPostBack)        {            if (CheckBox1.Checked == true)            {                if (Response.Cookies["travians"] != null)                {                    HttpCookie cookie = new HttpCookie("travians");                    cookie.Expires = DateTime.Now.AddDays(-1);                    Response.Cookies.Add(cookie);                }                Response.Cookies["travians"]["userid"] = TextBox1.Text;                Response.Cookies["travians"]["userpwd"] = TextBox2.Text;                Response.Cookies["travians"].Expires = DateTime.MaxValue;            }            Session["userid"] = TextBox1.Text;            Server.Transfer("default.aspx");        }            }

现在的问题是我把checkbox的勾子勾上以后，点button，page_load事件里认为CheckBox1.Checked 是false，所以不会执行保存cookie的语句，直接跳转到default.aspx页面了。CheckBox1的ecableviewstate属性是设成true的，望各位指点，谢谢

[解决办法]

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
if (Request.Cookies["travians"] != null)
{
TextBox1.Text = Request.Cookies["travians"]["userid"];
TextBox2.Text = Request.Cookies["travians"]["userpwd"];
CheckBox1.Checked = true;
}
else
{
CheckBox1.Checked = false;
}
if (CheckBox1.Checked == true)
{
if (Response.Cookies["travians"] != null)
{
HttpCookie cookie = new HttpCookie("travians");
cookie.Expires = DateTime.Now.AddDays(-1);
Response.Cookies.Add(cookie);
}
Response.Cookies["travians"]["userid"] = TextBox1.Text;
Response.Cookies["travians"]["userpwd"] = TextBox2.Text;
Response.Cookies["travians"].Expires = DateTime.MaxValue;

}
Session["userid"] = TextBox1.Text;
Server.Transfer("default.aspx");

}

}
楼主可以试试
