I'm trying to get my treeview control to work where a user clicks on a parent node. The node will expand.Then, the user clicks on another parent node and that node expands while the previous parent node stays expanded. My problem is that when I expand one parent node, another expanded parent node collapses.What am I doing wrong?

I am writing a programming using Tree View. I have created the Tree View object and have added a node for the root called Favorites. I want the user to be able to enter a value in a text box and once clicking on an add folder button, an event fires that takes the text that was entered in the textbox and creates a new node under the root node of favorites.
I am having a problem with my program in that the user is not able to click on the Favorites root note in order to create another node underneath of it. Favorites is simply displaying on the screen, but they cannot click on it to select it. What do I need to add so that the user can select the node to which they want to add a child node to?
