Selects will not open a dialog on only one page

Selects will not open a dialog on only one page

            I have a multi-page document in which I have several dynamically populated selects, and although the source appears identical between each of them, only one pages items does not open the <a href="#ddlName" > dialog. The dialog href is properly named and all other items I could check against working examples seem consistent. However for these broken large selects - Instead the dialogs appear over the current page and I can read the text of and interact with the buttons in the page as if the dialog was not even there.

The differences between the sets of selects are as follows:
Working version - located inside of a table that is a User Control, populated on the initial load of the page. Always visible when on that page

non-working version - located inside of user control that is basically a div wrapper set for structure and visibility. This starts inside of a style="display:none" div and shows as visible on a button press in the page. This select is populated on a postback to the server in which the values of the select are populated.



      Is this a situation where the initial page load sees the selects as empty and thus it does not create the structure for the dialogues even when they are filled? (I had assumed a full submit style postback would allow that structure to rebuild, as they are filled before the response from the server and all the data is available)

It may be something else, small selects work perfect on this page.


*If I am unable to fix this, I assume I can change the dialog source to simply have an href of '# 'and the large selects will work like the small ones do (not showing the buttons behind), but I would prefer to keep separate page dialogs going if possible.
