Samething like the picture below.

Hi Peter Zhao,

You can modify the default ControlTemplate of the RadTreeViewItem to implement this scenario. You can find more info on how to edit ControlTemplates in Blend here. Currently the RadTreeViewItem Template Structure contains a Grid RootElement, which represents the layout root for the template. It defines two rows - in the first one is the ContentPresenter and in the second one is the ItemsPresenter for the child items. So if you change the rows to columns, you will be able to get the desired look.

I attached a sample project to get you started.

Hi Tina:

I have played with the application that you attached. it looks very nice. just one thing I need to ask you about for the tree, for the first element of each level we have the top edge, it isn't very nice. is there any way we can remove it?That will be very helpful. Please see the attached picture that highlight part.


Cheers,
Peter
