Hide/Show TreeView Button-Help Urgent!!!!!

[aspengal]

I have a c# .net application and I have created a report which has a TreeView on the left. I enabled it via the property :CrystalReportViewer.displaytreeview = true
But what I dont see is a button on my tool bar where I can hide/show the Group Tree View. Also, I dont see a print button. In my code I have written
crvViewer.DisplayToolbar = true
crvViewer.HasPageNavigationButtons = true
But What do I write for Hide/Show Group Tree and Print Option?

Pls. help!!!!!

Hi...Thanks a lot for the idea..but my crvViewer does not have this property. When I hit a . after crvViewer, it does not show the hasToggleGroupTreeButton in the dropdown..
Anything to do with the Viewer? How Do I find what viewer my report is using? Iam enhancing the report and I dont know how to find what is the viewer..
Thanks
