dynamically populating Usercontrols

[John Ninan]

I am creating Dynamic Usercontrol in Asp.net application. In this application
I have a combobox(aspx Page). Which contains various items. Based on item
selected I am dynamically populating Usercontrols.
Problem:
When I am populating dynamic user control (ascx) page in Page_load event it
works fine for the first list item from combobox. When I change the item in
combobox, usercontrols are build properly but value will be same in second
page as first page. I debug and found that new value is assigned but in
control it is not changing. I have no idea what’s going on?

Thanks in advance for any thoughts.
