Treeview style issue

[El]

EDIT: [RESOLVED]

How do i overwrite the existing style for the RadTreeView control?
In the source i can see the rendered elements having specific CSS class e.g. rtLI rtLast
I need to adjust the height of the links decreasing the margins from the top and bottom.
Also i would like to change the text-decoration style to none, which currently is underline.

Thanks

My bad. i had some css style in conflict with the treeview. Now everything works just fine. thank you.
