_ctl5:_ctl0:p1456 in webform textbox

Steve Steve

Hello

I've got a bit of a problem here!

Right, I manage my shopping basket on my shop website by just storing
the ids and quantities of the products the customer has added in the
Session - the textbox name that I use in product view to add a quantity
is a "P" and the itemid to pass to the next page - because there are
variants of the same product I have to create these rows in code but
when they submit they append "_ctl5:_ctl0:" to the beginning in the URL.
This isn't really a problem in itself as long as this remains the same
so when I come to request I can check for:
Request.QueryString["_ctl5:_ctl0:P4321"] for example to get at the
quantity value. 'P' followed by the id of '4321' so in the url I might
have expected &p4321=100 if a customer selected 100 quantity.

Right that explained - here is my problem - for the second time now this
"_ctl5:_ctl0:" has changed - this time to "_ctl4:_ctl0:" spontaneously
and it isn't the first time it's happened! That means that from a fully
functional basket all of a sudden I get server errors because the id
passed from textbox has changed.

My Question then is can this appendation be altered or bypassed
altogether so that this problem goes away?

Thanks
Steve

I've managed to fix this on my application but not to my satisfaction -
it seems the field that is causing my problem is an HtmlInputHidden
which we set server side - I create the hidden like this in html

<input type="hidden" id="recno" name="recno" runat="server">

i.e. I set no value but runat=server so I can set it in code.

When the control is then created on the page the prefix is already there
- I assume it must be something to do with running it at server?

My solution is to store the prefix in the session when a control using
it is created (from base.UniqueId) and then the Session variable is
available when I need it. The problem with this is that I'm building a
site where the Session needs to be kept to a minimum to preserve RAM as
one of the requirements and I'm loathed to add more variables to it than
needed.

If anybody knows how to remove this prefix altogether when the control
is created could you please post and then I can get rid of the extra
Session var?

I have read about someone subclassing the radiobutton they were
including and overriding the UniqueId of the control they were creating
but I'm not sure where to start with this - any insight would be
appreciated.

Thanks
Steve

hi steve, your controls are put in that namespace because they are child
controls. This is necessary to maintain unique ids through your page.

To remove the prefix you need to remove the control from within the
container(parent control) you placed it in.

Since physical appearances seem to be so important to (some) in this group,
why don't you and F*** post *your* photos ... ;p

btw, given that you, PP, are a sheeted man o' mystery, I thought that you
perhaps merited a grand tartan - a purple plaid ("PP") - and that's why I
posted this photo of you:

- nilita, who thinks she actually had a jumper made of that material once
upon a time ...

Why, Nilita, I didn't know you cared...

I don't care what I look like and certainly don't give a damn what
anyone else thinks. You, on the other hand, seem peculiarly coy while
being terribly concerned about your own and others' opinions of them.
And with all that coyness, you protect your 'secret' so poorly that
even I (who don't care) know what you look like.

In your case, you shouldn't be so concerned about your looks until you
fix your personality, which is sufficiently ugly to overwhelm mere
physicality.

There are no photographs of me.

(For some reason, they just come out as shadowy,
enigmatic forms half-hidden by dark, swirling mists...)

I saw it the first time, but as it only resembles
a *part* of me, I didn't comment on it...

Oh, all right, if you absolutely need an Image, this one might do:

(Although it's of a new member of the SPU, who was
only dead-dhrunk at the time the photo was snapped.)

And, actually, here's a candid shot of *you* in the same state:
