Cookie only displayed on refresh?

Question

I have some trouble understanding this one so here it is.

I\'m trying to set a cookie and display the value on the page using ASP.NET + C#.

Answer 1

The first time, the request has no cookies (yet); it will only have them the second time around, after the response has set them. So your code has to deal with the possibility that Request.Cookies just may not have a "fontSize" entry, and provide the proper default when that is the case. For example:

HttpCookie cookie = Request.Cookies.Get("fontSize");
// Check if cookie exists in the current request.
if (cookie == null)
{
   Response.Write( "Defaulting to 'small'.");
}
else
{
   Response.Write( Request.Cookies["fontSize"].Value);
)

Answer 2

The lblChangeToSmall_Click event is fired after the Page_Load event. Therefore the cookie write won't be available on the Request until the subsequent postback.

It will be avaialable on the client immediately though.
