Hello pardeepkgupta,

We have several methods that can be used to find certain node(s) by value, text, index etc. They can be used to find both parent and child nodes of the tree. You can view them and read short description here - http://help.infragistics.com/jQuery/2012.1/ui.igtree > Methods

On the tree DOM elements you can of course use all available jQuery methods.

Inform me if you have additional questions.
