I am using the ajaxslideshowextender for a simple slideshow. I am analysing web traffic with Fiddler and I am seeing that the webpage hosting the slideshow is posting back every 25 seconds! When I comment out the slideshow code the page stops posting back, so it definately has something to do with the slideshow. Does anyone have any ideas why this could be happening?

 AutoPlay - Setting this to true will play the slideshow automatically on render.

PlayInterval - Interval in milliseconds between slide transitions in play mode.

I guess your PlayInterval is set to 25 seconds

I understand the properties, but how do i stop the postbacks? It only needs the slidedeck once.

 Hi,

You can define the following code to disable the timer to do tick.

$find('behavior')._timer.set_enabled(false);
