树形视图控件对象的创建[需要紧急帮助] [英] Tree View Control Object Creation [ Urgent Help Needed ]

问题描述

在我的树形视图中，每个节点都在调用一个新表单.之后，当我离开该表单并返回时，将创建一个新对象，这会占用大量内存.
我想使用第一次单击节点时创建的对象

我关注的建筑是CSLA

说

我单击一个节点[Node A]，然后调用新表单[form A]，并创建一个对象[obj A].

当我单击下一个节点[节点B]时，将发生相同的过程.

但是一旦我回到[form A]，就会创建一个新对象[obj A2].在这里我要使用[obj A]本身.

我该如何实现?

我是新秀.请帮忙.

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.
