I have a modalpopupextender and a Jquery plugin, ALS(http://als.musings.it/), the elements of the scrolling list is populated dynamically.
Since, the dynamic elements are heavy and needs database transactions to occur, the flicker at page load is quite evident.
To counter the flicker, I tried setting the display to none, style="display:none" in the panel containing the popup, but doing this, the scroller vanishes.
I am unable to make the scroller work and stop the flicker at the same time.
Any help is appreciated.
