Asp.net - Appending Strings And Link Buttons Together

I want to create a function that will make a treeView out of link buttons. Then I want to tie all the link buttons to one click event. So each time the user does somethingI will append the users name to the current linkbuttons if the user clicks one of the link buttons a click event is raised and I can extract the text of that button.

Here is an example:
Nick
...user does something...now the link string says
Nick > Jeff
...user does something...now the link string says
Nick > Jeff > Charlie
and so on.

Now I want to give the user the ability to click one of these link buttons (there are 3 in this example). If the user clicks one of the buttons a click event is raised and I can extract the name out of the text of teh link button.
