few days back i spent alot of my time in
googling about bindable controls creation on runtime but whatever
tutorial/article i follow fail me to achieve my purpose mostly at 99%
which makes me crazy coz this doesn’t happen with me only 1 or 2 times 
so i decided then when i will achieve this functionality i will must write blog about it and solution as well 
finally today i ‘d like to talk about dynamically controls creation
in asp.net which i found quite easy but for newbie it become quite
hectic because to create control at runtime is not an issue but to
persist them after post back is an issue even u keep their
EnableViewState property true :), solution is quite simple but that
depends upon scenario/need. if you need to create such controls e.g,
gridview, datalist, repeater,.. which need to bind then simply follow
following steps:
- create controls in Page_Init event
- bind controls in Page_Load event
thats it :) its a matter of two steps but drive you nuts if you
don’t know coz those controls which created on Page_Init doesn’t
persist after postback if you just create them in Page_Load and in Not
Postback condition coz it will be created once when first time page
loads afterwards it wont be created so u wont be able to see it again
but if u don’t put Not Postback condition then everytime it willl be
create suppose if you create edittable grid (or any control) and u edit
something and press update button next time but on page_load event it
will create all controls again and somehow bind as well if u r binding
then ur modifications wont remain anymore so …………… :s that was just a 1
scenario so if you bind again and again your modification wont persist
and if you don’t create control again and again on each postback ur
controls wont persist 
so the solution is to create controls in Page_Init event without
putting condition of Not postback and bind your controls in Page_Load
event under condition of Not Postback …
few solutions i would like to write which are somehow out of the
scope of this article but you might get whilst working on asp.net
binding controls …..
sometime when we want to bubble event means we use datalist and in
datalist we put button and button will fire event of datalist which can
be capture in Item_Command event of that datalist, WONT BE FIRE if you
write databinding code of datalist in Page_Load event without or out of
condition of Not Postback so keep your databinding code under Page not
postback condition.
you can’t rebind your code from bubble event means if you have any
button/linkbutton/image button or any such control which cause postback
and fire event of datalist don’t try to rebind your datalist in it ..
coz it wont happen from there 
may be some time you found problem of getting some events fired twice it happens when your AutoEventWireUp = true so keep it false (good practice)
i will post couple of sample code very soon or you may post comment with your email id to get sample codes via email
