Bypassing INamingContainer for server controls on page

T

TS

Steven, i lost this message conversation from outlook express and made a
post online (see last one on this page). Please answer it as it hasn't been
yet.

thanks


The clientID of our controls have become very long since
we have 2 master
pages that our pages inherit from. Some team members at
work are thinking
they want to override ClientID for our controls (custom
controls inherited
from normal .net controls) so when the controls are
rendered, the id we
specify for the control also is the clientID. This will
minimize the size of
the response to the client.

I have tried to think of all the implications of this, but
can only think of
it affecting scenarios where there are templated controls,
mainly when doing
ITemTemplates and specifying controls in it, such as in
grid editing.

If we were using a 3rd party control and it specified a
control with a
similar id as one of ours, this control would most likely
implement
INamingContainer and thus there would be no conflict with
our control I
don't think.

If we never plan on doing in-grid editing, can anyone
think of any other
things that the proposed solution would hurt us later?

thanks

asp.nets calling the controls loadpostback data event
depends on the
rendered control id matching. another option is to make
the masters id
short (can be set in the masters oninit).

right, they have gotten them to match so the only
scenario is whether or not
we will be susceptable to other problems in the future
since unique naming
would be nullified.

what ways could break this code in the future?

thanks Bruce!

Hi TS,

I agree with Bruce. The reasonable and safe approach is
try reducing the
naming for the master page or any parent container as much
as possible. For
the ClientID, the built-in default implemention is derived
it from all the
super level NamingContainers. This is quite important when
the server
control is nested in any other parent control container or
template
container(such as those template databound control you've
mentioned). And
for such scenario, the hierarchical naming rule will help
the ASP.NET
runtime to associate the client-side postback element to
the server-side
control. Therefore, I would surely recommend not to
override it (remove the
hierarchical naming format).

Steven, you said:
"...the hierarchical naming rule will help the
ASP.NET
runtime to associate the client-side postback
element..."

we have proved that the plain clientID without the parent
container's id
prefixed does run correctly and identified correctly.
1. Are you thinking that it might not be possible or that
it is less
efficient without the hierarchical searching?
2. Like i've said it all works without the containers'
prefix, so i still
need some more compelling reasons why not to do it.

thanks

Hi TS,

I assume you're referring to this post:
http://msdn.microsoft.com/newsgroups/managed/Default.aspx?dg=microsoft.publi
c.dotnet.framework.aspnet&mid=3055846c-93b8-46b7-b8b7-9d5b2642b2c6&p=1

Steven is not in office these days, so I will work with you on this. Sorry
for the delay since your reply in the previous post somehow didn't show up
in our tool.

I've carefully reviewed the post and I totally agree with Bruce and Steven.
INamingContainer is designed to make the IDs unique on the whole page, and
the IDs will be the cornerstone of how ASP.NET engine uses them to
correctly handle states or route events.

However, I agree that your suggestion is reasonable, it's just currently
ASP.NET is not designed to let you override the ClientID.

Hope this helps.

thanks

are there any other scenarios or types of controls like templated controls,
where the unique ID based on hierarchy would need to be in place without
naming collisions or other bad behaviour?

thanks

Hi TS,

Thanks for your reply. However, I'm not sure if I fully understand your
question. It's not the template control that has this special behavior,
it's all that the interface INamingContainer matters. It's only a marker
interface (an empty interface); when ASP.NET engine generates the
ClientID/UniqueID, it will use the interface and ID property to determine
them. Currently it's better to let ASP.NET generate them and use them, if
you do change them, some built-in function may or may not work since it's
really not designed to be changed by user code.
