CascadingDropDown and IsPostback

Med
Hi,

Is it possible to populate CacadingDropDowns if !IsPostback and preserve the
content in postback senarios?
My two CacadingDropDowns call my WebService and get populated regardless of
IsPostback condition.

i.e. I only want to populate the child CacadingDropDown when its parent's
index has changed, like convesional dropdown.
Kind Regards

Hi Agian,

Sorry guys, as soon as I posted my question I realised I should have moved
my Cascading drop-downs out of the ajax Update panel and it worked.
