Hi Aravindba,

I have implemented the same in my project once, It reminds me once you asked this question,
will paste my code for you here so that you can make use of it in your code.
container.find("#btn_CollapseAllPennyTests").unbind("click").click(function () {

container.find("#btn_ExpandAllPennyTests").unbind("click").click(function () {

I hope this would help you.

For that you should find out the child node class name or id name, with that you may do the same thing that i have done.If you check parent node then all child node under that parent node so you might use toggle() for child nodes i believe.
