Tree View Control Object Creation [ Urgent Help Needed ]

C#

In my tree view in each node am calling a new form . After that when I am navigating away from that form and come back a new object is created, that is consuming a lot of memory.
I want to use the object created when I first clicked the node

Architecture I am following is CSLA

Say

I click a Node [Node A] then new form gets invoked [form A] and also an object [obj A] created .

When I click the next node [Node B] the same process happens.

But once if I went back to [form A] a new object [obj A2]gets created . here I want use [obj A] itself.

How can I achieve this?

I am a rookie. Please Help.
