Hello,
I have an aspx file where i've put a placeholder element. On load
(page_load) i create dynamically an html table which contains a checkbox and
a radiobuttonlist in each tablerow . The radiobuttonlist contains two items
(yes,no). Both the
checkboxes and the radiobuttonlist are NOT autopostbacked ( .autopostback =
false). When i press the submit button a sub (submit_pressed) is run. My
problem is that i can not get the selected items in the radiobuttonlists.This
is caused cos in the page_load event i call the sub that dynamically
recreates the table described above and so all values are reset (there is a
rdb.item(0).selected=true line in my
code. If i try to remove that line of code, the radiobuttons keep their
values or not,after each submit, without a pattern (at least not one that i
can see)!). I've also tried to keep the values in a collection, instasiated
in the page_load but i couldn't do so cos the table (that contains the
checkboxes and radiobuttonlists) is not recognized at the beggining of the
page_load (i guess it's not an object yet cos the sub that creates all that
is at the end of page_load)....
Anyway...any ideas on how to get the selected item ? ? ? ?
thx a lot

here is a portion of the code
in vb code
--------------------
1. create the (html) table through code
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As

end sub
3. when the submit button is pressed ,i try something like
private sub submit_pressed
dim otable as new table
dim tr as new tablerow
dim tc as new tablecell
dim chk as checkbox
dim i,displayed as int16
dim rdbDisplayed,rdbAdult as radiobuttonlist
'plh1 is the placeholder in the html code

tr = otable.controls(i)
tc = tr.controls(0)
'tc.control(0) is a checkbox
chk = tc.controls(0)
'table cell
tc = tr.controls(1)
'tc.ctontrol(0) is a radiobuttonlist
rdbDisplayed = tc.controls(0)
'****************************
'the following line always returns item(0) cos the sub

before the submit_pressed is called
displayed = rdbDisplayed.selecteditem.value
'*****************************
if chk.checked = true then
'show displayed
end if
next
end sub 4 3986
Remove the bind from your Page_Load and put into its own routine. Only call
from Page_Load if it is not a Postback. If you need to rebind, do it from
your button click after you retrieve values. Ordering of events is fixed, so
you have to be flexible.

juststarter,
I have some example code on using dynamic controls on my website: http://www.aboutfortunate.com?page=codelibrary if you go to the given page
and use the search box there to search for "dynamic" you'll get all the
examples in the search results. There are only about 3 or 4 and I think that
it would benefit you to take a look at them.

Thx both for your help,
what i did is the following :
in page_load event i added:
if not page.ispostback then
call addControlsInPlaceholder()
end if
in the submit_pressed sub i added the following line in the end of the sub
(so that i recreate the html table after i save the values of the
radiobuttonlist :
call addControlsInPlaceholder()
the problem is that the line (in the submit_pressed sub) :
otable = ctype((plh1.controls(0)),table)
is returning an error because plh1 doesn't have any controls any more.
Doesn't the placeholder retain the controls added to it, after the postback
is done, or am i missing something?

juststarter,
No you have to recreate any controls added dynamically to a page upon each
page load.
