hello,

I want to know what are the benifits of Collapsable Panel Extender,

We can do same thing with JavaScript also ?

If I am having 5 to 6 panels on each page of my Application, then is there any Performance realated issue to be cared of ?

Hi,

Atlas is in fact using javascript/ecmascript on the client to create such behavior. The benefit of such controls is that they're easy to use and you just need to set some properties to get another effect while coding it yourself would take a certain amount of time.

Grz, Kris.

i think its easier using div with style like visibility or display than this control. Sorry but i was listening to the video who show how to use this control and its easier with javascript and a stylesheet.
