Multiple dynamically created web controls, one event handler

Question

Hello all.. I have a table where one column has DropDownList controls. Rows are added dynamically using a LinkButton. Each new row creates a new DropDownList control. I have one SelectedIndexChanged event handler that I associated each DropDownList control with. I recreate my table from cache on each postback. The DropDownList controls do seem to call my SelectedIndexChanged event, but I cannot even assign text to a Label I have statically set on my web form. I also cannot use Response.Write in my event handler as I am told by ASP.NET that "Response is not available in this context". So I get a vague message that has no other useful information. Is there something wrong with using numerous dynamically generated DropDownLists in a table column and a single even handler to handle all their SelectedIndexChanged events? Is there maybe some referencing issue with the DropDownLists? Any help or advise would be appreciated. Thank you.
