Forms and hidden fields

[Roshawn Dawson]

Hi,

Are hidden fields passed in the querystring when a form is posted back?
If they are, must the hidden fields be server controls in order to
access them from .net code?

Thanks,
Roshawn

No, they are passed in a form post which is different from a query string
(but has a similar effect)

AFAIK you can access them directly as Request["myHiddenField"] or
Request.Form["myHiddenField"]

but if you want to access them as server controls you can do that as well,
just declare them in the usual way:

<input type="hidden" runat="server" id="myHiddenField" name="myHiddenField"
value="xyz">

I always make the ID and Name the same in this case - it's not strictly
necessary but a lot less confusing.

no..not in the QueryString but if the input is of type=hidden then yes
they are passed.

Thanks guys for your prompt responses.

It seems that one of you says that hidden fields are not passed in the
querystring while the other says the opposite. Perhaps I wasn't clear
enough.

What I mean by hidden fields is hidden form fields. You know, the input
fields whose type is specified as hidden, like this:

<input type="hidden" name="227" id="227" value="stuff that is hidden" />

Are such fields included in the querystring or not?

Thanks,

Hi,

If you are using method="post" in your form element, the hidden fields will
be sent in the Request Collection when you submit the form.

If you are using the method="get", it will be sent in the query string
