Problems updating cookies 1

[jgd1234567]

Hi, i'm having some problems updating cookies. I have the following code when a user submits a comment:

Response.Cookies["Comment"]["FullName"] = txtFullName.Text;
Response.Cookies["Comment"]["Email"] = txtEmail.Text;
Response.Cookies["Comment"]["Url"] = txtUrl.Text;
Response.Cookies["Comment"].Expires = DateTime.Now.AddYears(1);

And then in my page load i have:

if (Request.Cookies["Comment"] != null)
{
txtFullName.Text = Request.Cookies["Comment"]["FullName"];
txtEmail.Text = Request.Cookies["Comment"]["Email"];
txtUrl.Text = Request.Cookies["Comment"]["Url"];
}

The first time i post a comment the cookie is successfully set but if i post a new comment and change one of values the cookie doesn't get updated.

I have just read the msdn documentation and it suggests that my could should work for both creating and updating the cookie but it doesn't seem to update.

Appreciate your help. Thanks

have you tried removing the cookie and adding a new one.

protected void ButtonClick(sender object, eventargs e)
{
   if(cookies["comment"] != null)
   {
      cookies.remove("comment");
   }

   object[] data = new object[] { 
      txtfullname.text,
      txtemail.text,
      txturl.text 
   };
   cookies.Add("comment", data);
}

protected void PageLoad(sender object, eventargs e)
{
   if (!ispostback)
   {
      object[] data = (object[])cookies["comment"];
      if(data != null && data.length == 3)
      {
         txtfullname.text = data[0].tostring();
         txtemail.text = data[1].tostring();
         txturl.text = data[2].tostring();
      }
   }
}

Hi, i'm a plonka. I forgot to wrap if (!this.IsPostBack) around the first part in the page load so the contents were always getting overwritten.

Actually, jmeckley emphasized an important point. Your cookies won't update unless you re-add them to the Response.Cookies collection.

It sounds like you must be doing that, but it's nice to note.
