Collections and maximum Count/Length

[Dan Flynn]

I am working on a project that requires me to check the number of rows
in a table with the same HTML "ID" value.

I do this in my code with:

i = document.all(rowid).length

However, if the number of rows with the same ID is greater than 8, it
always returns 8 (not 9, 10, etc.)

Also, I am seeing a similiar response in a 2nd page when I attempt to
get the number of elements in the Form collection

i = Request.Form.Count

This also returns a value of 8 although I know there are more elements
in the collection than 8.

Is any one aware of an issue like this? Maybe some kind of setup
issue with IIS?

Please help.

Thanks.
I am hoping this is a

More than really weird. Double check the names (and this is the name
attribute rather than the id at least server side). Are they all inside the
same form tag ?

If you can't find try just the simplest code possible to see if you have the
same problem (basically a loop that renders 10 fields).

What behavior do you expect from document.all? And why do you think a
browser should tolerate such abuse of the ID attribute? When uniqueness is
the specification, violating it entitles us to little indignation.

get the number of elements in the Form collection

i = Request.Form.Count

This also returns a value of 8 although I know there are more elements
in the collection than 8.

What do you see if you dump Request.Form to the Response stream?

ex: Response.Write(Request.Form)

For that matter, are you depending entirely on the ID attribute, or are your
form elements utilizing NAME? In HTML4, NAME is required for a "successful
control":

I have never seen IIS truncate the Request.Form collection. I can only
assume the browser is not sending anything else.
