Using ModalPopupExtender in ASP.NET Repeater

Question

When using ModalPopupExtender inside a repeater, when the page loads, ALL of the popups appear without being called ( one for each item in the repeater) and then rapidly dissappear.
With this, the popup works , but the problem is these popups being showed at the beginning. The popup is an OK/CANCEL popup, that triggers a postback when OK is clicked and does nothing when cancel is clicked. It is loaded on page load so that it exists when the user clicks on a linkbutton on the repeater. When the user clicks on the linkbutton, our intention was taht the popup appear directly without doing a postback, and this was achieved , just that small problem that random parade of popups at the beginning!thank you in advance!

Answer 1

I was not able to answer until now, sorry. Turns out the HTML code and the CSS had conflicting codes and that made the popup appear!
