Hii all Experts,

I am working on a page which contains a ListBox lstboxSelect containing details and Button btnOK which is Disabled or Enable = false by default, On selectIndexchange event of this Listbox lstboxSelect I want the Button btnOK should get enabled which is working fine.

My problem is on runtime the selectchange events fires for first twos or three time properly but then after sometimes it stops working the Button btnOK doesn't get Enable even after I select the item in Listbox..

plss help I tried debugging it but no help plss help me

Note : Autopostback property of Listbox is set true i.e. LstBox Autopostback = true
