I have a Model outline as follows,

Parent - 1
-- child 1
-- Child 2
Parent - 2
-- Child 11
-- Child 22

By default Sapphire rather the Eclipse outline does not show the child noded unless we expand the parent node.

Is it possible to make the parent node automatically expanded and show the child nodes ? or alteast when the parent is selected.

Forcing tree expand on node selection would defeat whatever the native behavior is for trees on the given platform and as such would not be appropriate. However, there is an enhancement request open that requests that newly added nodes be shown initially in fully expanded state. That may partially satisfy what you are looking to address.

Can we make it to trigger at a click of of button or something, with in our action class ? So that if the user feels he wants to expand it he can .

Are you asking if you can make an action that will expand some portion of the tree? Yes, you can do that using the API that I referenced in the other thread. Of course, there are already expand-all/collapse-all buttons in the content outline header...
