Hi Doraemon,
Thank you for writing back.
The expandable control that you see in our demo application is a custom control built precisely for it, which is not distributed with the suite. However, there was demand for such control, hence we introduced it. It is called RadCollapsiblePanel. You can find its documentation here:
http://www.telerik.com/help/winforms/panels-and-labels-collapsible-panel-overview.html.
Inside of this expandable control, there is a
RadListView with items in it.
As to the right hand side, there is
RadPanorama with tiles, and when a tile is clicked, a UserControl is shown.
Attached you can find a sample of this.
Regards,
Stefan
